Yes this is occuring in a clean project without any additional content .
Create a new blueprint project without any content, create a blueprint with a static mesh and within the tick function or anywhere else use "Paint Vertices Single Color " on that mesh.
This should work in editor . But the Dev build crashes .
isnt this only relevant for the leveleditor ?
The editor itselfe does not crash when using the vertex paint tool.
What i am trying to do is change the vertex color at runtime and the builded game then crashes when trying to do so (works in a shipping build)
I was put in charge of investigating this issue. I noticed that while testing I could only reproduce the crash when setting the vertex color on event tick or If I set the color more than once using a delay. If I set the color once using begin play the issue didn’t occur.
So to be more precise if there is already vertex color information painted using this node and you try to add a new color that is what causes the crash.
