Hello everybody! First excuse me for my poor english.

Here is my problem: If I use an alpha textured skin in a model at MED it seems to be all ok, but when I render the world at game engine the "Zorder render" of all the alpha textured meshes goes crazy. I have read about people with the same problem using other moddeling software and they solved it using no alpha textures but mask textures. I ask if somebody know how to use alpha textures correctly with MED or some alternative.

I hope somebody could understand me and thanks!

I seem to be having this problem as well.

if i add a targa texture of 32 bits with alpha channel my model becomes partly 'see through'.

what is the correct usage of alpha.

hoping for a quick response.

sincerely yours,

I was investigating hard this problem some days ago, and this is the best info I found (from FAQ page of 3dgamestudio):

Q. "I have problems with the sorting of transparent entities or alpha channel textures. For instance, I'm trying to make a tree by crossing two sprites like a 'X. When using 32 bit TGA sprites, the first sprite is always drawn before the second sprite. This doesn't happen when I use PCX or BMP or 24 bit TGA sprites."

A. "Transparent entities (meaning entities with TRANSPARENT flag or with an alpha channel texture) can not write into the z buffer. Thus the engine sorts them according to the distances of their origins. Nevertheless, transparency causes visible errors when objects intersect or when a concave mesh consists of transparent polygons. You just have to think a little to avoid those mistakes. For instance, make your 'X' from 4 connected sprites rather than 2 intersecting sprites, and separate a transparent mesh into convex parts."


In my case I have a bone-animated concave mesh, and I need to use transparent textures but I have no idea of how to separate my character mesh into multiple parts. I hope somebody could show me some hints to do this with MED or 3DSMAX (the software I'm learning to use now), or show me some usefull links. thank you all
