Ok, so you probably know how to get proper GI effects using point clouds, right? If that's not the case or you think it is a bit hard to set up, then you have to take a look at the new GI tab in 3Delight for Maya 6.0.
First, you need this scene:
Now, create a render pass and render that scene with default values and persp camera. You'll get this fantastic image in i-display:
Well, now let's put some magic there. Select the render pass and open the attribute editor. Go to "Global Illumination" section, open and select "Point-Based Full Global Illumination" from the "Effect" drop down menu:
That's great, isn't it? We didn't use any volume/surface shaders or pre world mel!Ok, there's something in the shadowed areas that doesn't look great. It is because we are using 8 bits to display this, let's change that and render again (we will be using multi layered exrs to render this, anyway ;) ).
That was easy, fast and looks rad!
I won't spoil the fun with boring stuff but it is a good idea to read the fucking manual, which is very complete and will help you get nice renders in time.
