How to get those multicolored shadows? I see in a lot of WIP-images people rendering their models untextured, but with a nice looking light. It's like there is a multicolored spectrum in the shadows. How do they achieve this? I see it in almost everyones "clay renders" (or how you call it). When I just render my model with a standard light source everything is completely monochrome.

The only way for me to achieve something like this is to add a 360-image as world background and set the light and image details to reflect in the model. I don't think this is how they do it.

Here is a couple of example on what I mean:

Those are not colored shadows, shadows don't have a color per-se, they are just e slightly colored light sources.

Just add a slight tint to your lamp objects so one has a warmer redish tone, and the other has a cooler tone towards blueish or green.

This is generally done using a Three Point Light system, which is a well know lighting technique in photography also.



Optionally if you want more realistic shadows or natural lighting use a sphericall environment map in your scene's World nodes, Ideally HDR based or as regular JPG image.
