Hello Why normal map looks good when the render start than it become bad? [n2] [n]

I haven’t had time to check yet.

That first image looks wrong too…would it be possible to get the model?

Yes [image] Bugatti Type 57SC by stunner2211 Model of a Bugatti Type 57SC. Thanks Poupediepapedie for the model and the permission to publish it. I only repaired it and make it printable. It has no special scale and should be printable. If anything is wrong with the files, contact me. +++…

I found the problem, and I have a fix ready for this. Essentially I’m writing the normal pass more often than necessary. You can follow here: RH-63236 Normal channel looks incorrect

PR is cooking. Should be in the next 7.5 SRC.
