Problems with shadows and trees


05-08-2008 05:36:02

I setup up a paged scene with caelum, and I use the shadow technique SHADOWTYPE_TEXTURE_MODULATIVE and it works but there are these weird "things" (shadowy square quads) over some of the trees that should not be there. This is a shot of it:

Also when I set it to other shadow techniques, the "weird quads" don't exist.

What could be the problem?

in the tree material you have to set the alpha rejection parameter

My understanding is that SHADOWTYPE_TEXTURE_MODULATIVE does not support transparency and alpha channels.

I don't know a whole lot about Ogre shadows, but I think you have to set up the shadows to use transparency, and you also might want to disable self-shadowing on the trees if you can.
