Uniform sampler2D tex // illegal to put “uniform” in struct
#Glbindsamplers opengl 4.4 drivers
The bug we fixed is that we forbid this by mistake, where in previous drivers we allowed it. However, there is no restriction that the sampler can’t be in a struct which is declared as a uniform-qualified variable.
Basically the spec, in the absence of bindless texture, only allows samplers to be declared as part of a uniform-qualified variable.
#Glbindsamplers opengl 4.4 driver
The OpenGL 4.4 beta driver had a regression where we became too restrictive with samplers in structs. Is this allowed again? Is this behavior conformant to the spec? It seems a bit of a grey area… After reading the spec it seemed as that this was ‘more’ clarified in the current GLSL spec as when i implemented it first and samplers were somewhat allowed in uniform structs. I did a lot of changes in my project to remove samplers from structs (strictly used as uniform) after testing the OpenGL 4.4 beta driver. With driver versions up the the 326+ line everything worked as expected and understandable. To rule out blending or depth testing these options were disabled. However everything I tried failed to get control back in the main function to write even just a plain color. I tried to break down the ray casting function to get it to return some debug values. I know that the function is working because I write per-pixel feedback into texture images (image load store) and I can see the intersection results are fine. The problem seems to be that the shader is terminating the ray casting function but is not returning control to the main function somehow. However, with this shader code I should get blue everywhere. The problem I have is that where the ray does hit a surface I get red color and everywhere else blue. layout(depth_any) out float gl_FragDepth Layout(location = 0, index = 0) out vec4 out_color #extension GL_ARB_shading_language_include : require I have these things wrapped into a nice function so the shader does look something like this (broken down to illustrate issue): I have a fragment shader which is doing some quite complex things (ray casting a height field).
I ran into a quite serious bug with the OpenGL 4.4 beta driver which I was able to reproduce with all 326.x drivers available from the NV website.
