So I was building a scene with several of these trees and was going to cover the ground with flowers for a video I am working on. I am trying to get everything to look as realistic looking as possible and was experimenting with path tracing. However, it is causing some issues that I haven’t been able to troubleshoot. I put an alder tree in a new level by itself so that I can troubleshoot and try to get it working right.
The picture on the left is lumen and the picture on the right is path tracing. You can see issues in the mesh and textures in the trunk and there are some leaves and branches disappearing. I tried disabling wind (though not sure if I missed disabling something), and I have been googling this issue to death and tried a few console commands for similar issues but nothing is working.
Can I get this tree to work with path tracing? What could be the problem?
