Wrong smoothing groups with Birth Objects - BeyondReality.de - 12-05-2019

There is an issue with smoothing groups when using Birth Objects. See images below.
Only Auto Smooth will work, but that will produce other issues. I use Vray Instances.
Any ideas?

Which version of tyFlow are you using?

Also please provide the file.

I'm using v0.16061 with Max 2020 and Vray Next.

File is attached.

It seems like a normals issue, not a smoothing group issue. The mesh appears to have explicit normals set, which are not supported by tyFlow...thus, overriding the smoothing group of 1 set on all the front trim. Since tyFlow doesn't support the explicit normals, the front trim sides/face are all being smoothed in the same group, thus you see the rounded appearance.

Ah, I see. Thanks. For now I had to look for a workaround.

Any plans to support explicit normals in the future?
