I don't have any other holograms at this time.

Just fabricated a grand projector in order to test for the problem.
Same exact issue exists: pink opaque square where the hologram should be.

I don't see any errors to do with my mod here, did you send the logs after you encountered to problem? (So, installing a projector, clicking on it and changing what hologram it should have etc). If not please do that and send me the logs

Yes, I sent the logs after I encountered the issue. I can select the hologram and access the buttons for the options like color, etc. but instead of displaying the current projection, it shows a dark blue box with an X in the middle.
When I try to choose a different projection, a shadowy box pulls up, but nothing else.
It's almost as if the mod cannot access the images files, because everything else seems to work. I can change the color, switch between light and darklight, and cycle the modes.

Ah, found it! It seems the new shader I've written isn't compatible on your GPU, what GPU are you using?

(Also make sure to update your graphics drivers!)

MD Radeon Pro 5500M 8 GB
Intel UHD Graphics 630 1536 MB

As far as I see, everything is updated.
Is it possible to make it compatible or do I have to unsubscribe from the mod?

I've just uploaded an update that might solve the issue, let me know if that's solved it

Your mod disappeared and I couldn't access it. Steam said the link was wrong or whatever. I had to search for it in an unconventional way to be able to reply. Not even the Workshop would show it.

Just saved and exited the game. Steam updated Rimworld. Launched and loaded my save game, but the same issue persists.

Okay, just updated and that should have a fallback shader working now.
It won't look as good without having my custom shader but it won't be a bright pink square at least!

(Also if the mod disappears it's because Steam has to verify a mod after it updates, whilst it's verifying the mod is hidden)

No idea why but this mod suddenly made my pawns start to do weird things. When they hunted they would try to shoot through walls and my guns did barely any damage. No logs cause it never generated an error, but removing this mod from my save fixed the issue instantly.

I'd love it if you recreate the problem and send the huglib logs regardless as it contains more info than the in-game console
