Newly found TGA exporting BUG
Exporting TGA sequences at 1280x960 does not work -- it creates a series of TGA files that are completely black. Please attempt to replicate this bug to verify this is an in-game bug, and not something wrong with my system.
How to replicate the bug:
1) Record a demo in single player Half-Life 2
2) switch to 1280x960 resolution
3) playdemo [demoname]
4) startmovie [whatever you wanna call it]
On my System this results in a series of black TGA files being produced. Regardless of the host_framerate setting or any other settings I could think of. If you must know, I am using 24fps as my export setting.
UPDATE:
After more testing I realized this error (above post) occurs at any high resolution. It is appears to be related to a memory leak if I had to guess.
After a certain amount of time while exporting a demo the process just seems to go sour -- giving you TGAs with no information in them (black images).
Exporting at higher resolutions will cause this error to occur faster in the demo sequence (once it happens, every TGA frame thereafter will be black).
Thus -- exporting at 1280x960 resulted in virtually immediate black TGAs. Exporting at 1152x864 gave me about 250 frames before going sour. Exporting at 1024x768 gave me about 400 frames before messing up. Exporting at 640x480 seemed to cause no error as I completed exporting the entire demo without incident.
YET ANOTHER UPDATE:
Turning off NVIDIA'S "8s" antialiasing down to regular "4x" aliasing seems to fix the problem completely. I just exported the entire demo at 1280x960 using 4xAA and 16xAF
Is NVIDIA'S special aliasing mode causing a memory leak?
Does the source engine have issues with NVIDIA?
Or both?
Or, is it simply the fact that using 4AA uses less memory and therefore doesn't cause the error?
Well ... those are the remaining questions that someone else is gonna have to figure out. At least I found a solution.
Anyway as you can see, this appears to related to the higher resolutions creating some kind of problem.
