Hi to all... always me... I have another question for you.. My vertex struct is the seguent: struct CUSTOMVERTEX { FLOAT x, y, z; DWORD color; // Diffuse color FLOAT u,v; FLOAT u1,v1; }; For some polygons i need to disable the diffuse color component.. Is it possible? I don''t want to change value in the vertex struct because i need to use the value in a second moment.. Thx, Alex

You''ll need to do:

  
pDevice->SetTextureStageState(0,D3DTSS_COLORARG1,D3DTA_TEXTURE);
pDevice->SetTextureStageState(0,D3DTSS_COLOROP,D3DTOP_SELECTARG1);

But why do you need to disable the diffuse?

Thanks works great.
I need to disable diffuse color, because for some shader i need to do different pass and in some cases i need to render polygons without considering the diffuse color component.
