bright red objects

When i use retextures or replaces, i can see some red objects. Can i fix it? With what it can be connected? this is definitely the fault of OR. when i off OR - all ok

In general this happens when the texture replacement package (or the relative mesh) is not correctly made.
OR is not able to detect it correctly while the vanilla game is able.
Wait for the new version that will be out soon, probably it solves the problem because all the shaders have been rewritten.

Thanks for the answer! i'll be waiting
