[BUG] 4.26 crashes every time I try to vertex paint

NatCLK · December 31, 2020, 2:03am

This is driving me insane. :o

Every time I try to vertex paint anything, the engine freezes for a few seconds and crashes. This happens with both my own materials and quixel blend materials. I didn’t have this issue with 4.25 so I guess this is a new bug?

I had the same issue. I had to go back to 4.25.4 as vertex paint kept crashing the engine with 4.26

4.26.1 and still crashing with vertex painting:

It crashes with Direct X 12 and also with Direct X 11

Fatal error!

I had the same issue

Is it possible, that you have the “Modeling tools in Editor” plugin enabled? I had crashes as well when doing vertex painting and could track it down to this plugin being enabled. Unfortunately, I could not submit a bug (the submission does not work for me). Here is the link to my thread on the forum for this.
