hi marcus,
i tested following shader, with latest catalyst driver:
// Fragment Shader
#version 440 compatibility
uniform sampler2D s_texture_1;
out vec4 s_frag_color;
void main()
{
vec4 v1 = textureProj(s_texture_1, vec3(0.5, 0.5, 0.5));
v1 += textureProjOffset(s_texture_1, vec3(0.5, 0.5, 0.5), ivec2(1, 1));
s_frag_color = v1;
}
// end of GLSL
no error was observed.
as you can see here:
textureProj & textureProjOffset are not deprecated.
so, can you share your shader that generates error?
so that i can reproduce your issue.
thank you.
regards
davy
