Hey guys, I sort of know how to create shadows from triangulated objects etc.. But I have some textures quads with multiple textures per quad and one of these texture layers is the shadow. Currently the shadow is nothing more than a texture with a positional offset. Is there a "standard" method for projecting this texture layer on the scene so I get a "real" shadow which takes the lighting position into account and possibly even the type of light? (spots) Am I looking at a projective texture? (and how to project it regarding the light(s) ?). I'm using directx, any ideas, links even :) ?

Yup, sounds like it. What you're looking to do is to set up your texture coordinates such that they're the vertex's world-space position projected into the light's view frustum (i.e. you build a view + projection matrix from the light's point of view).

Thx SP, I think i'll manage that, any way to have it "wrap" around objects behind it?

Techniques to use?

The dumbass that I am just realized that its just shadowmapping i'm looking for :)
