Compute Particle system in asset section, No visual, does not seem to work

compute particle system v2.0 or 2.1 in asset section gives an error
Compute Shader Compile Results:
ERROR: /ComputeParticles/Particles/glslParticleSystem_compute:90: ‘texel offset’ : argument must be compile-time constant
ERROR: 1 compilation errors. No code generated

I wish I could fix it, but I too rubbish at GLSL, I did try.

Ok code makes no errors now, but still nothing to see, does not render anything

Probably best to post to the thread for that community post so the author can be alerted
