Hello,

 

I have always been stuck on this one which is how to use the vertex alpha component in a mesh that has,  Position, Color, Uv, & Normals.

 

I found something that mentioned this  :

 

d3d->SetTextureStageState(0, D3DTSS_ALPHAARG1, D3DTA_DIFFUSE);

 

but it does not seem to work.

 

Any ideas ?

 

Thanks in advance .

Try something like the following:

device->SetRenderState( D3DRS_ALPHABLENDENABLE, TRUE );
device->SetRenderState( D3DRS_SRCBLEND, D3DBLEND_SRCALPHA );
device->SetRenderState( D3DRS_DESTBLEND, D3DBLEND_INVSRCALPHA );
device->SetRenderState( D3DRS_BLENDOP, D3DBLENDOP_ADD );

OH yes, but actually, thinking about it. I just want the vertex transparency without having to use vertex blending,

 

Thanks anyway.
