Hi guys


I am having a little problem with a loop in my pixel shader

int i = start;
	i ++;

	if(lt[i] != 0)
		color1 = shaderTextures[i].SampleLevel(SampleType, input.tex, 0)*lt[i];
		//image processing
}while(i < 8);

When i try to compile i get the error X3512: sampler array index must be a literal expression

for the line where the texture is sampled. Does this mean that I cant use a loop counter variable in the array? How can i get around this so i can prevent textures from being sampled when not necessary without going into a brute force method using a whole string of if/else statements?
