I don't know if HunoPPC will answer (here or anywhere) but I just want to give you some informations.

First, I post here without asking him if he is ok with that.

Second, I know him since many years (decades), I visit him time to time and I can confirm he works on Doom 3 since 2 years and a half or more (he showed me Doom 3 before covid-19, so).

I talked with him about this "drama" yesterday and he explained me and showed me why his debug is similar : he looks where there are VBO and shaders "problems" to correct them, so it's normal and logic that he wants to have a debug like this. Shaders don't work out of the box and the compiler, even on OS4 and their 3D driver.



KennyR : Did you take a look at his others developments ? What you wrote is not useful and that doesn't help...
