Chams problem

Thanks for reply.
To Biesi : What do you mean "Creating an overlay on textures doesn't make walls transparent"?
To Void : This is my Chams code :
if((m_Stride == 52))
{
pDevice->SetRenderState(D3DRS_ZENABLE, false);
pDevice->SetTexture(0, texRed);
pDrawIndexedPrimitive(pDevice,pType D3DparamvalX,nMinIndex,nNumVertices,nStartIndex,nP rimitiveCount);
pDevice->SetTexture(0, texRed);
pDevice->SetRenderState(D3DRS_ZENABLE, true);
}

So if I understand you're saying it's sort of working? Do the characters show up to be red when they aren't behind a wall?

Yes the Chams is working.The characters show up with red Chams when they aren't behind a wall.When they are behind a wall I can't see them with red Chams.

Sorry I dunno how to post image,please click the URL thanks.

Do you mind posting all of your code?

Because he wants the characters to be different color when they aren't behind a wall. Well, that would be the case if he didn't use the same texture in both those instances.

Which game is this? In some games models are not always drawn behind walls for performance reasons. Anti occlusion can be server side or client side, if its client side then you can hack it, you need to hook CreateQuery for that (vtable index 118). You can google "anti-occlusion v2" for code example.

This is Mission Against Terror 2 CiB.Maybe MAT2 cannot.Thanks for all your reply.I will try anti-occlusion v2.
