[ARK_3D_bureau]

Hi

Maby you already know how, but I just find a way to make those fine rainbows in the caustics



to mutch here.



thats more like it.

I just render tree same pictures in tiff format, but with my IOR in the
1 picture at 1,50
2 picture at 1,53
3 picture at 1,56

Then in photoshop I take the blue layer from picture 3, and the green layer from picture 2, and overwrite the existing blue and green layer in picture 1, and then the finish result should se the light

looks great. You can actually do it from within the render though, by using a blend material for the r + g + b and giving each material a slightly different ior.
