yes - that should work.

Precisely- If using a pixel shader output such as: struct PS_OUTPUT { float4 PosInViewSpace : COLOR0; float4 NormalInViewSpace : COLOR1; }; can I expect that these will correctly end up in the render targets I set, for example: SetRenderTargetEx(0, posTexture) and SetRenderTargetEx(1, normTexture)? > From: [email protected] > > I'm looking into doing deferred lighting.
