Texture lights breaks on some screen's

[xdedeone]

Hi. Im having an issue using chimera in 2 diferent screens. One is my laptop screen, and the other my secondary screen. When i opens halo with splited screen, some texture's breaks lights and get dark zones

the texture can be showed making light reflection (flashlight or explosions)

This only happens when halo game starts on screen 1 (laptop) only screen 1 or splitted screen makes dark zones, starting game only on screen 2, textures can be showed as expected.

Also, with game minimized started on screen 2, returning to split screen, game looks fine on screen1 (lol)

So, idk why is happening. Maybe an bug or something? My laptop is an Acer Nitro 5, mi 2 Screen is Samsung.

So, the reason this is happening is nothing to do with your system or graphics hardware, or a bug specifically in Chimera.

The issue is the map itself and Halo PC being incompatible the the "p8 bump" bitmap format.
This map contains a tag formatted in p8 bump format (Xbox), but because Halo Custom Edition had broken shaders, no one noticed.
Now that Chimera fixes bump map rendering in shader_environment tags, the invalid texture is causing the ground to render incorrectly. This would have always happened if the shaders in Halo Custom Edition worked as intended.

The real fix would be to implement software decoding of p8 bump in Chimera, so it would render as it would on Xbox.
A workaround would be to have Chimera dereference bump map tags in the p8 bump format, so it will use the valid default texture.

The map could also be changed to use an uncompressed bump texture (as was intended on PC), but you are unlikely to get people to agree to use the fixed version over the originals.
