How To Use Global Illumination For Realistic Light in Cinema 4D 229 Comments


In this tutorial, I show you how to light a simple scene using luminant materials and global illumination in Cinema 4D. First, I show you how to set up, model and texture the scene using Mograph type and simple primitives. Then we use GI to realistically light the scene.

Global Illumination is notorious for being hard to use and slow to render. It can definitely be tricky to get it looking right without rendering all day. That’s why I also try to explain a bit about how GI works and things we can do to make it do what we want and get it faster. I hope to be talking much more about GI as Iv’e been taking quite a liking to it lately. Especially for still renders. Enjoy!

This tutorial is based on this awesome piece called Let There Be Light by Jeff Osborne. Big thanks to Jeff for making such a great looking render!

    What would you use instead of GI for animating amazing looking scenes if it is best only for still images?

      Hey Dave

      Im really sorry if you feel like this mate.
      The idea came from the Bible Genesis 1:3.
      I had a post on abduzeedo.com http://abduzeedo.com/amazing-3d-typography-jeff-osborne
      a while back and some guy said the same. I had a pop at him saying that i didnt even know that the set up was there in cinema. A likely story you may ask, but the truth nether the less. But as you did create quiet room before i had created Let there be light, i should credit you with the idea of the tube lights, even if i didnt know you had created them!

    • all i can say to that is hmm ships with c4d, made in c4d and light tubes made in 3d. all at the time you made urs lol OH PLEASE ffs but ofcourse it was all ur idea to hand light tubes in c4d and use gi with a skirting board on the wall at the exact time i did the same and even shipped it with c4d.

      Perhaps though, the creator of the bible saw into the future and loved Dave’s render so much that it inspired the verse. Bible author please come forth and give Dave a high five!

    and i have a question

    is possible to adjust the gloom/bloom from lamps inside c4d? whitout goes out to ps for post adjustment?

    ps tweaks are great and mostly needed, but maybe we can achieve better results inside cd4? also, to get more blurry reflex comes from ground, maybe increase the reflexion material could help to “bump” or i just think wrong? a thinnest noise could also help on image aspect?

    • Cheebachops

      There is a glow option in the render settings, but it’s fairly poor.

      Reply
    • Adding the glow in Photoshop or AfterEffects just keeps things more flexible, rather than risking your beautiful render being ruined without the possibility to remove the effect.

      Before Cinema had blurred reflections a very fine bump map was the only option. Blurred reflections are much better although far slower to render.

    Hi Nick! This is great!!
    I was thinking about that, if we make the letters -> rigid body, and the floor is the collider, and we just let the letters fall down… may be we get some similar result. What do You think? I’ll try it.
    Have a great day to everyone!

  12. I have a question about your render vs. Jeff’s. In his render, it looks like he has some strange lighting effects going on. If you notice, especially on the under side of the dot of the i, on the left and underside of the g, the inside of the b and the e, it seems like there is light where there should be shadow.

    Your render looks more realistic, and you can tell exactly where the light is coming from, but I kind of like the effect that Jeff’s render has.

    Is it just me, or is something a little strange going on there? And if so, how do you think he accomplished it? Is it just more reflected light coming from the adjacent letters?

    • Jeff Osborne

      Hey Adam

      I used a material with a slight amount of luminance that give s the extra lightness.
      I wasn’t going for realism, I was going for something that would make the piece stand out more.

    Hey Nick,

    Thanks for another great tutorial. Here’s my try:

    http://www.flickr.com/photos/gjtenhove/5241998437/

    I coulndt get the render bright enough with the lights. I even crancked the brightnes up to 800% and coloured the walls and ceiling white to get more brightnes. It dindnt work untill i turned up the gamma from 2.2 to 4 and made the back wall and floor a bit lighter. Where did i do something wrong?

    By the way, it took my iMac G5 intell core duo 2Ghz about an hour to render. And because its night in Holland it took two beers instead of a coffee to wait for it.

      Rather than maxing out the lum.ch. on materials when using GI, try the illumination tab and increase the “generate GI” level.

      It’s more about realistic light calculations from GI (light bounce etc) than a photo-realistic image study.The tut. showed you how to get a close approximation of the original image, which was itself not supposed to be a real world scene.

      Thank you Nick for the consistently great tutorials. You take the time to provide us with useful information and you do it on your own time and for no profit. Instead of just showing us a c4d tool or function you show useful examples of how to apply them.

      I made a neon sign text with a text spline.
      I used sweep nurbs witht he text and used a small circle spline that extruded along the text to look like a tube.
      The material was just a coloured luminance channel. I made it ‘fresnel’ with a gradient the ran from white, to red, to pink.

    Hi Nick, just wanted to clear up some things for people here about lights and GI.
    The C4d lights are all capable of been used with GI renders (i think it came accross like they were no good for it in your first segment.I’m guessing that wasn’t your intention).
    The R12 basic lights even have photometric settings to imatate real world lighting values.
    IES lights include data from the manufacturers for shape/fall-off etc.

    The second thing i need to mention is that the specular option on materials is also calculated during GI renders.The effects are not as pronounced as in non-GI, but when cranked-up they work.

    Lastly i’d like to thank Nick for taking the time to pass on the things he’s (by his own admission) learning, and wish other posters on this blog would stop saying something is dull, just because they already know it or don’t want to.
    To me this blog is about sharing knowledge with those who want to learn, and helping each other(and Nick)improve those C4d skills.

    • Here here! Nick is kinda just showing us “Loop it, Swoop it and Pull” but we all have to tie our own shoelaces. If you already know how to tie your shoes then move on to tying the Chinese Pan-Chang Knot and share with all how you did it.

      As for that Alex Roman guy, WHOA! that is the Pan-Chang of realistic rendering hands down. Crazy.

      Also cheers to Nick for your time and info. It’s not easy one bit to record a fluent and organized tutorial one bit. For some one to even just learn one small tip or trick or get an idea to try something different in their own style then mission accomplished for the creator and the viewer.

    • You can get some not bad results by setting up a depth pass and render it out as a multipass layer. In AE use it to fake DOF. C4D cafe would have lots of info on this in forum and tutorials.

      Reply
    • Kevin

      Depending on the composition of your shot, you can fake it in AE. Render out your foreground, midground and background as separate passes. Comp them in AE and apply blur to get your desired result. You can also use masking in AE on a shot that’s not layered.

      There are other ways i.e. plug-ins etc but this is the cheap and easy way.

    Hi Nick! I tried the rigid body vs. collider theme. You said : “not enough control”. I would say: almost nothing control :) .
    I hoped, that after the falling, I could move the letters. I’m so unexperienced. Yet.
    Well, the niggling around the starting position to get different results seems it takes more time, than just setting it Your way.
    Thanks, it was something to learn! ..and more to come. Have a great day!

      The mograph dynamics major flaw is the lack of control over the resulting simmulation.
      If anyone at Maxon knows of a way to gain access to the simulation data, please tell us.

      I’ve tried using the mograph cache tag to bake the frame, then do make editable/current state to object, but the sim always resets.

      There must be a way to do it as the data is there somewhere, but even xpresso is no help it seems.

    Hi Nick! Awesome tut as usual! I was just wondering about one thing. Out on a tutorial on Pariah Studios (http://vimeo.com/11022627) I saw that Robert Redman used a normal-inverted cube as a room for his lighting. I was wondering if there was any advantage over using an inverted cube to 4 planes for the bouncing of light rays? Or do they just do the same thing anyways…. o_O

    Reply
    • Cheebachops

      It’s the same thing, just something to bounce light off.However you can find the cube is less versatile with regards to camera placement.
      You can also cheat better fill lighting effects with floating planes because you can angle them to bounce light into poorly lit areas. This can be an immense help in some scenes as you don’t need to increase the diffuse count so much.

      In c4d (as far as i know)there is no need to invert the cubes normals as long as you use the default double sided setting for your materials.
      Other 3d progs are much fussier about normals for light interaction.

      Reply
      • I would agree. Planes give me more independent control and don’t get in the way of the camera as much.

  26. Thank Nick for another great tutorial, I always learn something new here. I´think maybe the standard way of lightning would provide a faster result. Instead of using the luminance channel to light the scene, using area lights and applying them to the objects (Cylinders, in this case). With the physically accurate falloff and very soft shadows it might provide similiar results. Worth doing a little test, imo:)

    Reply
    • Sure thing. Let me know how it looks. The big problem with area shadows in this situation is that you have bouncing of light.

    • If you grab that little slider bar right under the timeline ( on the right and slide it sideways it will change the increments. But it only shows what will fit in your space.

      If you ALT click the brail box right beside the EDIT menu item on your VIEW tab; click it a few times until your view screen maximizes everything, then just click the brail box things on the bottom to bring back your timeline.

      I looked in the pref’s and doesn’t seem to be a way change the increments, which makes sense cause as you adjust the preview range the timeline needs to accommodate. On the bottom time line you can zoom in like in the view finder and always have increments of 2, but you will be panning back and forth a ton to find keys in a long timeline.

    • I thinkk my way would be to split that spline into two and run a sweep nurbs. Then I’d just add the buld end caps to the top and bottom points on the sweeps to cover up where they don’t connect. This would be an easy way.

      Other wise you can use spline wrap and that will bend your tube light along the spline. Your Cylinder will need to be very tall and have tones of height segments so it can bend smooth around those tight corners. Also change the intermediate points on the spline to natural or uniform ;)

      Hi xstean, your whole scene looks underlit, try to increase the diffuse count and make sure your light bouncing walls aren’t too far away from the main comp.

      If you’re happy with the overall scene lighting and just want lighter Text, try altering the text materials illumination setting for “recieve gi strength”

      Hope this helps.

      You need to increase the samples.
      Large flat areas have fewer calculations during GI pass due to optimisation used by renderer.

  33. Hey nick…

    Got a question for you or anyone that can help me with this:
    I wanted to try out this tutorial as well, but instead of a still image, I wanted to give it some motion. Where the hanging light-bulbs are flying into the scene. But I got a bit of a problem with this! I’m trying to give them some natural dynamics swinging from the cord they are attached from. But I can’t seem to get this done. I’ve made some tests and this is what I got so far: http://vimeo.com/17765679
    I can get the cord to swing without the light-bulb, I can get the light-bulb to swing correctly using chains (from your dynamic chain tutorial), but when I attach the light-bulb to the cord, it just falls to the ground and stretches out the cord?! Any idea how I can solve this? So that my light-bulb attached to the cord is swinging just like the chained one?

    Reply
  39. Like most of yours, great tut, thanks for sharing.

    I wonder if you couldn’t use dynamics in a controlled way to make those pieces sit perfectly. Instead of froppnig them from a great height, couldn’t you place them roughly, about 2 cm or so from the surfaces you want them to fall against so that they land ideally and more importantly, physically perfectly. If you set the gravity and friction correctly, you should be able to do a minimum of work positioning the letters roughly, and then perfect their real-world physics by dropping them. What do you think ? I’m gonna give it a go.

    Hey, your tutorial is really nice, helped me a lot. But I still got a question.
    If I use GI with the luminance channel only, it looks really nice, but if I use a “normal” light, I get some other realistic shadows. Take a look at the two pictures (especially at the window), one with GI and one with a bit GI and a “normal” light

    I just have a basic question about C4D that I cannot figure out! In your tutorials, the perspective view does not show a grid. Mine always does and I’d like to learn how to turn it off. Thanks for your help and the great tutorials!

      It could be sooo awesome if you could make one of the lightpipe-thingy cracked/destroyed- so the glass was around the destroyed pipe :D Nice work :)

  45. When you render there is allot of boxes going around and it seems really quick, on mine there is 2 boxes, how do i make it like yours.

        And why there are 24 boxes??? Generally is one box one core. So it should be 12 boxes. Do you use a special render-addon or -plugin for something like multithreading on each core???

      Take a look at the preferences, you can use twelve boxes aswell which makes the rendering go faster, but will tear apart your cores. U can change the max ram for the picture viewer, but it all give ur machine a terrible time.

    Hey Nick Ive been having some trouble with the GI with an animation im doing from the tut that you did above. wanted to know some correct settings for animation just using GI. the bulb i have rolling into the scene and its the only light source involved but i keep getting shadows that look very nasty and flickering all over the place. Here is a link to the image if that help.

  52. Oh boo… my comment didn’t come thru. Made the first one… rendered straight outta c4d:

    and then i decided to combine the tut that lights up using objects only instead of GI… I couldn’t get the glow of the bulbs to show up very well on the floor. But it was worth experimenting with.

    Hi
    Excellant tutorial as always…

    I am building a neon sign using similar techniques I have learnt from this tutorial.

    However I want to have the glows, reflections all as an alpha channel. This is so that I can then have the sign as a transparent PNG with shadows/reflections and glows for my website. I have learnt a bit about the composite tag, but is this still possible with GI? Or do you have a better suggestion to save all those lighting details as a transparent element.

    I have built my sign using an outer glass tube, and then an inner luminant tube to create the neon gas.

    Cheers

    Set the random effector over the floor, then put on them Dynamics and let them drop

    Thanks a lot! Turned out to be simpler than it looked.
    I will definitely use this knowledge in the future.
    All the best!
