Hey after a long discussion with vtastek and testing and stuff i had to replace all "Density" in my timelygodraysv3.fx with the word "dens"..we don't still know why that changed anything but hey,made it work for me lol
After some investigation, we found the shader is active in all passes. But it fails to draw rays. After getting confirmation that, he has an Nvidia card, I was sure there must be another problem.

I decided to check his old OGE logs.

It is interesting there is only one value which is reported wrongly.
"Density"
I suspected a name conflict, and suggested to rename the variable. It worked reportedly. But I have no idea why could that happen in all those variables to 'Density'. And I noticed I used saturate as a variable. There is a function called saturate, may conflict. I should changed that.
