Working GI sample

[rdb]

I don't speak for tobspr, but I might be of some help. I hosted the missing sample files here:
http://rdb.name/tobspr_renderpipeline_demoscene.7z

You will also need a patch for the GI to work on non-NVIDIA cards, tobspr hasn't committed it yet:

Thank you for that ! But it seems that it isn't working. I have enabled global illum in the .ini file, but I always have a white screen when I isolate the GI pass... Another problem, but it's just a warning :
:display:gsg:glgsg(warning): Program undefined behavior warning: Sampler object 0 has depth compare enabled. It is being used with depth texture 26, by a program that samples it with a regular sampler. This is undefined beahvior.

NB: it's an NVIDIA Quadro K2000 card with the latest drivers...

GI has to be enabled first in Config/pipeline.ini, and you need my shader fixes. Did you apply the patch that I linked?

[cedricp]

No, as you mentionned that it's for non-Nvidia cards

[rdb]

It may apply to NVIDIA cards as well, and it certainly doesn't hurt to
apply it. In any case, even without the patch, you still have to enable GI
explicitly in pipeline.ini.

I've applied the patch, it's the same, if I disable/enable GI, only the bottom of the curtains are affected

[cedricp]

enableGlobalIllumination is already set to True by the way in pipeline.ini

[tobspr]

Hey, I will commit a patch for the global illumination soon, however, your issue seems to be that you enabled useHardwarePCF, which enables depth filtering. With that enabled, a depth texture cannot be sampled in a normal way, thus the GI does not work properly. Try disabling the PCF, and see if it works then. I'm working on a fix for that!

Btw, thank you rdb for hosting the files 👍 I'll think of a way to include them in the repo

[tobspr]

I've committed a fix, including rdb's patch, lemme know if it works for you!
