Well i am trying to alter the vertex color in my game , and this is working great in Editor.
For testing purposes i used the node “Paint Vertices Single Color” on a simple static mesh.(new project)
And as stated in the question this causes the game to crash in a Dev. Build.
It does not cause the game to crash in a Shipping Build.
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)
Even at runtime you will still need to ensure the material can accept vertex color data. If you add the vertex color node to a material, do you see a difference?
Do you have a sample project this is occurring in you’d be willing to share or steps I can take to reproduce this on my end? I’ll be happy to take a look and see what may be occurring.
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.
