As I posted lately, i’m trying to export a model from blender. But I get an error related to nodes. I searched a bit on the internet, and it told me that the object was “empty” (without nodes) because I didn’t select the object that I was trying to export.
I had the same as this one yesterday on one of my planes. It was created on blender 3.1 and then opened in 3.6.
One of the materials has a problem. I started to delete objects grouped by material one by one. It apparead to be the collision material in my case. I deleted it and recreated it with exactly the same parameters and it stopped failing.
Is this by any chance a model where you used decimate to create lower LODs? I got such errors after decimating, and I solved it by re-doing it again with a little less decimation. I’ve also tried leaning up lose vertices before doing that, or tried deleting by distance to clean up a little before (or as an alternative).
