Hello, according to my previous post here, I unfortunately still have the problem using Microsplat with MM2. You can see the screenshots of the error on that post here: https://forum.unity.com/threads/released-mapmagic-2-infinite-procedural-land-generator.875470/page-36#post-7750713 and I also made a video to show you when it happen https://www.youtube.com/watch?v=Fzp4TIfkJok&ab_channel=MichaelSimard
It is not just when texturing via a spline. An error seems to happen if I add 2 time the same Microsplat texture. but also I start to have some problems when I use many different ones.
