Shadowmaping solution

[isaac]

Hi, Truevision does a formal solution for shadowmapping? (with alpha or skinning)

thx

If I understand your question, you are asking if TV6.5 features a built-in solution for shadowmapping. The answer is: no. TV only has a built-in system for stencil shadows (which are slow).
But there are some great examples on the forum (with source) which show how to implement shadow mapping by shaders.

      this is a formal solution for my.

Which of these do you recommend?

Toaster's shadowmapping

Zaknafein's shadowmapping

They're not alternatives to each other. Toaster's is for point lights and Zak's is for directional lights.

i can opt to use directional or positional lights in my project depending on how effective their shaders are. anyway, both shaders looks great

[Zaknafein]

I should say that my solution is not a "reference" directional shadowmapping implementation. It's complicated because I set myself the constraint of not overriding the landscape splatting shader.
So I use per-chunk shadowmaps that map to SetCustomLightmap()s and try to keep as fast as possible.

In short, if you want to override the landscape shader, there are much simpler (and better) ways to get fast shadowmapping.
