Shader Error, Wrong Information

On this GPU only;

AMD R9 380

But this is the code at that location and it does not match what the error is saying.  It sounds like a texture ID that used to be an "int" and now is a "uvec2" is being compared wrong but I can't find it!  @Josh Could the 0:199 information be off somehow?  Maybe it's in bytes or character stride instead of the line index?

[Josh]

Upload the shader please?

[SpiderPig]

Sent it to you.

[SpiderPig]

Sent you the updated shader and updated this first post to reflect the new errors.

[Josh]

Texture handles are a uvec2, using bindless textures. Just change line 100 to this and it will work:

	if ( material.textureHandle[ 15 ] != uvec2(0) ) {

 

[SpiderPig]

Why would this have compiled okay on some GPU's and not on others?

[Josh]

Some GLSL compilers are more strict than others.

[SpiderPig]

Ah okay.  Were you able to tell if the error messages were actually showing the correct line?

[Josh]

On my AMD 6600 this was the output:

Error: Failed to compile "C:/Users/Josh/Documents/Ultra Engine/Projects/DLCs/Materials/DynamicSky/DynamicSky.frag"
ERROR: 0:100: '!=' :  wrong operand types: no operation '!=' exists that takes a left-hand operand of type ' temp 2-component vector of uint' and a right operand of type ' const int' (or there is no acceptable conversion)

Also, there is a NULL character at the end of the file, which should not be there.

Ultra creates a shader source code by adding multiple files' contents together. It uses the #line directive to indicate what the current line and file index are, before every single line of code, since it is merging a bunch of different files into a single string.

What GPU is creating this output? It looks like it is not evaluating the #line directive correctly.

[SpiderPig]

Ah okay.  For the exact same code the AMD R9 380 said it was at 0:199.  That's going make debugging shaders fun if some cards don't give the right info

Ah yes I saw that after I gave you the latest code.  That's fixed now.
