After considerable trial and error, I got this result:
It's borderline OK, but the 0.3mm corner radius and finish is pretty accurate for a machined and tumble part. However, if I try to apply a "bump" to my surface or if I ungroup my part and try to apply a spherical map to my bolt head, I lose my corner radius:
....and so I ask the community:
- How do I retain my corner radius on my part after applying a bump texture? Dialing down the bump strength to almost zero doesn't bring back my corner radius.
- How do I retain my corner radius(es) on each part of my group after ungrouping? I've tried applying the corner radius on every individual part, without success.
