Hi guys!

Just one quick question, how would one specify multiple attributes to a loop, the attributes that are needed for my shader to operate are the following:

loop (The number of iterations is dynamic (float, cpu -> gpu), the compiler tries to unroll to infinity)
allow_uav_condition (Well, I need to read an UAV)

But for now I haven't found the syntax anywhere. Please don't say this is impossible...

Thanks!

You can concatenate attributes (remember the tesselation attributes) like so:


[loop]
[allow_uav_condition]
for (int i = 0; i < 12; i++)
{
   // blah...
}

Haven't really checked it with a sensible sample, but at least it compiles.
