Colored Shadows

[tomhanks]

I tried to find out about it on this forum but I really didn't find any answers to it.

In other 3D packages is very easy for you to force some color on the shadows, you just have to specify it´s color and that´s it.

I know that mantra is a very powerful render engine and some things that you can do with it they are amazing but some are a little trickier like colored shadows, it doesn't have a option ready for it, besides that I am new to Houdini, so I am just beginning to understand how it works.

Does anyone knows how to change a shadow color for a specific light?

Thanks, and sorry for the bad English.

Thanks for the tip.

I got a solution that works on the shader that´s applied to the object that is receiving the shadows, I just use the shadowmatte VEX SHOP inside the material to add colors to the surface using the shadow alpha, but that is a solution for some cases, what I didn't get was a solution for the entire scene.

There must be a way to replace all the materials from the scene at once without to have to set all the materials one by one, so that way I could make a shadow colored pass, but I don't know how.

Anyway I am posting my solution if you want to take a look.

Again thanks for the tip.
