Hi, in ps I use for(..) { output.color = ..; i = (i + 1) % N; .. } and get: "warning X3550: array reference cannot be used as an l-value; not natively addressable, forcing loop to unroll" Questions: 1. how to let shader still run in spite of warning? 2. Is there no way to output.color[L-value]? that means I have to do MRT like if(i ==0) color[0] = c; if(i==1) color[1] = c; if(i==2) color[2] = c; ... //3 is solved by: struct PS_OUTPUT { uint4 color[2] : SV_Target; uint yetAnotherColor : SV_Target2; //notice here is not SV_Target; float depth : SV_Depth; }; [solved]3. I have 3 MRTs, 2 of uint4, 1 of uint. How do I claim PS_OUTPUT? I do like this, I don't know if it's right: struct PS_OUTPUT { uint4 color[2] : SV_Target; uint yetAnotherColor : SV_Target; float depth : SV_Depth; }; Thanks! ps. hlsl warning is hard to understand, and sdk doesn't cover all. Is there any reference? Thanks! [Edited by - yk_cadcg on May 14, 2007 6:17:13 AM]
