A custom weapon that crashes the client

The short answer

A weapon that drops players to desktop is usually a texture format, a broken mip chain or a collision with another pack. How to isolate which.

A weapon that crashes on equip is doing something the renderer cannot recover from. There are three usual causes, and they can be told apart in about ten minutes.

#Rule out the collision first

Two resources streaming different files under the same asset name is the most common cause of a crash that appeared after an unrelated install. Stop every other weapon pack, restart, and try again. If the crash stops, the problem is a name and not the model.

#Then the texture format

A texture saved in a format the game does not expect for that slot — an uncompressed image where a BC-compressed one belongs, or a normal map written as sRGB — can take the renderer down rather than simply looking wrong. This is the usual outcome of a hand re-import that skipped the compression step.

The fix is to write the texture back in the format the original used. Not a similar one, the same one. If you no longer know what that was, the original pack is the reference.

#Then the model itself

A .ydr exported with a shader the game has no material for, or with a bone structure that does not match a weapon, will crash on equip rather than fail gracefully. This is a model problem and it needs the model rebuilt, not a texture edit.

  1. Reproduce on a clean server with only the weapon resource running.
  2. Swap the .ytd for the original, unedited one. If the crash stops, it is a texture.
  3. Swap the .ydr for another weapon's. If the crash stops, it is the model.
  4. Check the client crash log for the asset name it died on.

Questions

Why does it only crash for some players?
Texture format problems are driver-dependent. A file that one GPU tolerates will take another down, which is why a weapon can look fine on your machine and crash half your server.
Does editing a texture risk this?
Only if the format or the mip chain changes. Writing the edited image back into its original dictionary in the original format, with the mips rebuilt to the same number of levels, does not.
Where is the client crash log?
In the FiveM application data folder, under crashes. The asset it died on is usually named in the dump.
