Caustics

Unity Engine
1

Hi all,

I was wondering if anyone has any suggestions/tips/recommendations for making caustics in Unity?

I have a basic knowledge of what caustics are, but need a push in the right direction for doing this in Unity as I don’t have experience with Shaders.

Thanks in advance.

I have that, thank you.

I’m just not sure how to interpret that to Unity, how do you write shaders in Unity?

For example in Cg, see this wikibook:

Use a projector if your caustic light recieving geometry is not too complex.

EDIT: There is also the free Caustics generator program which outputs animated textures of caustics. Search google.
