Strange Phong/Smoothing in 2.5

OS: Windows 7 Pro 64bit
App: Maxon Cinema 4D R11.532 64bit
Plugin: 2.5.0 R11.5
M~R: 2.5.0

Simple scene - camera, MR Scene object, sphere, default grey MR material applied to sphere.
Remove phong tag from sphere.
Export scene to mxs.
Open in studio.
Sphere seems to be faceted.
Click it, it has "Smoothing" activated and set to 60.

Another testing: all objects from Cinema have "Smoothing" set to 60 regardless how you set it. I do not know if it is valid for other platforms, I do not know if it is plugin or "core" related.

If is someone interested in testing it, I can upload scenes somewhere.

Can anyone reproduce/explain it please?

This is the expected behavior.

That means that if you click 'Recalc', the normals will be recalculated using 60°. It does not say anything about the object itself.

As mentioned above, this is not telling you what the smoothing is 'set' to, it is telling you what will happen if you click Recalc. There is no 'smoothing angle' parameter contained in the MXS file, there are only normals, transferred directly from the modeling application.

:oops:

I did not know that... OK, I understand. Thank you very much JDHill.

I had some object in Cinema without Phong tag that seemed to be smoothed after render. So I wanted to check the settings in Studio. When I let the object render to higher SL there is really no smoothing.

My fault - sorry...
