Bindless Textures and sampler2DShadow

OpenGL OpenGL: Advanced Coding

Hi,

I want to sample a depth texture with a shadow sampler.

The texture is bindless and the homebrewed depth sampling/compare works as expected.

Now I would like to creeate a shadow sampler.

Code compiles:


		sampler2DShadow sShadow = sampler2DShadow(shadowTex);		 
		float isShadow = texture (sShadow, vec3(shadowTC, distanceToLight)).x;
		out0 = vec4(isShadow);

I tried several “distanceToLight” values but “isShadow” remains 0.

Am I missing something?
Solved:

Yes I was: The shadow sampler must be enabled.

glTextureParameteri(shadowTex, GL_TEXTURE_COMPARE_MODE, GL_COMPARE_REF_TO_TEXTURE);
glTextureParameteri(shadowTex, GL_TEXTURE_COMPARE_FUNC, GL_LESS);
