The T-Pose is consistent with positions being randomly set to zero, just like the environment. I notice the color overlay is also impacted, which makes sense. Though it doesn't seem entirely random, there's a pattern behind this madness... Those values come from somewhere, but I don't know where yet.
It's very difficult to troubleshoot on my side without being able to reproduce it on any of the GPUs I have access to. But if you have a few minutes to spare, we can play a game on ping-pong where I send you a new version of the drawing module and you test it for me. I've uploaded a new version at the same link: https://drive.google.com/file/d/1JDK0C7XWdVYmRBNPWErXcoVtMRglyu17/view?usp=drive...
I would be very interested to know if this version works (though the framerate may not be good). Thanks for your help! ;)
That's good news! At least you can play the game now, though I'm not ready to officially commit to this fix just yet.
So, thanks to your video I've noticed the positions of the meshes were not random at all. It felt like at least some parts of the environments were placed, scaled and rotated just like the character parts should! But on the other hand, the character parts were never scaled, despite the fact a lot of the environment is. So I assumed some meshes were drawn using the previous content of the buffer. I'm not sure why. From what I understand of it, it goes completely against the OpenGL specs, but that wouldn't be the first time a driver optimization goes wrong. My "fix" was to ask for a new buffer every single time, to make sure I start from something clean. That's completely overkill and why I was concerned with the framerate (and I do notice a general slow-down on my 11-years old GPU). There's probably a better workaround... I have a few leads if you're willing to test them for me?
And yes, the map is revealed from the start (your character already knows this place well!) and there's no marker for your current position. It was a (very) late addition to the game and I assumed the map was detailed enough that you could quickly locate yourself from your surroundings. The most important part about this map is that you can basically write on it ;)
