i got a major problem…since I tweaked a material unreal keeps crashing when I try to reopen the levels.
In my material function I reconnect nodes to a diffuse output. When the swatch is open on this diffuse output node, Unreal crashes.
When collapse this output node, Unreal stays alive until I open the levels that contain this material.
All levels are crash sensitive with these material.
edit: AppendMany node is causing issues. When I do the same outside this node Unreal is not crashing. See image.
