Hi,
I’m happy that you found it between the cracks. I agree that there are improvements. Unfortunately, there are still some issues that I mentioned in the first post. I really hope it can be resolved and I think you will agree with me, that even lightly softened edges drastically improve realism.
Of course, I need to work on NURBS objects and manually extracting render meshes is just to demonstrate issues.
RH7 Datasmith soft edges - 2022.3dm (2.8 MB)
1. Edge Softening of Breps still not transferring to Unreal
Datasmith
Please take a close look at Breps in Rhino - they have Edge softening turned ON, but after they land in Unreal (even with import option “Import Rhino meshes and UVs”) there is no Edge softening. Extracted Render Mesh obviously does have softened edges but I can’t use them because of constant Datasmiths reimports.
Direct Link
Interestingly, there is higher chance to import Edge Softened Breps by Direct Link… But sometimes there are issues when I modify Edge Softened Brep and do not change UV mapping.
It’s really confusing and there might be some coincidences, it needs some attention.
Rhino Scene and settings
2. Issues with welding?
Please take a look at Edges of Extracted Render Mesh - it has UV Box mapping.
