[0.4.0] [Blood] Some voxeled pickups appear blue

Post by markanini »

Raze vs Fresh Supply

Some but not all pickups appear with a blue tint.

This has been reported before, unfortunately I haven't been able to reproduce it myself so currently I have no idea what goes wrong. It surely picks the wrong palette but I cannot say what causes it.

It happens to me too, under palette emulation mode.

oooo-kayyy.
That little tidbit was missing before.
And that makes more sense because the voxels cannot use palette emulation - it needs to be disabled for them. I thought I had it working, but apparently some pieces are missing.

It happens even without palette emulation, 99% of times I ran into this was without it.

Me thinks it's memory corruption/undefined behavior, kinda reminds me of a bug Cheogh had back in the summer on Linux which caused him to occasionally display in brown :v.

Yeah, it somehow picks the wrong palette on occasion - if I just knew how to reliably trigger it...

Well there's the issue - it doesn't seem possible to reliably trigger it. Sometimes it's there, sometimes it's not.

The easiest way would be to just keep starting the game and warp to a map with plenty of ammo and voxels around until It Just Happens(TM) E1M7 was the easiest for me. I think it might also help first starting on a map, and then warping to another, just a gut feeling that it breaks when transitioning between levels.

A texture for voxel is converted to 32-bit only once, using the current palette. With non-default palette, e.g. underwater one, the glitch will appear.
A good example is the first map of Cryptic Passage. It has flare boxes in water and on ground near the staring location.

I've seen completely black voxels (the flare ammo and the exploding barrels) in e1m2. Is this the same issue?

It's a related bug. If some voxels are visible when player enters the game for the first time in the current play session, they will appear black.
Global palette contains zero at the moment of texture processing. E1M4 or E1M5 can be loaded to trigger this issue.

This issue also appears to affect Shadow Warrior as some of the key lock voxels in the train level of Last Warrior were completely pitch black. Hopefully fixing it in one game will also fix it in the other...

I did a complete rework of the texture generation for voxels. This code was still operating under assumptions that are no longer true in Raze - mainly that the original code flushed all textures on a global palette change. As a result it had no means to keep textures with different global palettes around.

Let's hope this works, but I can confirm that I saw the same voxel both underwater and above water in the same map and both looked correct.

The previously black voxels at the start of e1m2 look like they are supposed to.

Unfortunately it's still there in 0.4.1

The fix was after 0.4.1.
