Hello. I have converted my project from 3.2 to 3.3 and now every single object including particle systems are pink. the textures are in their place, everything is setup but nothing can be done since there are at least 1 thousand objects in a single scene of the same type. Is there anything I can do? It’s about Years of work gone down the drain if were talking about the damage.
Pink rendering normally means Unity is using a warning shader. Perhaps you have shader compile errors?
Lesson One - keep a backup. Especially true when about to upgrade a project. I hope you have such a backup
Sounds like the materials got disconnected. I had this happen so much I wrote this script to help: unifycommunity.com
Sorry to bring up and older topic, but I too had the same issue.
I was able to solve it by going into the texture resource, in the inspector change the textureformat, then changing it back to what it was and pressing apply. This returned each texture to its happy self.
