I am probably mising some connections --again!--but I can not understand why there is a problem?
(I generally,other times, save as n-gons to use in Carrara)

In this instance, after "softening" in Carrara I can do this easily.
Is that what is wanted?

Hi Brian, different polygon apps can work in slightly different ways.

If the polygon smooth shading ends up crossing over what should be a sharp corner, it can make some kinds of shading artifacts.

Some programs may automatically manage polygons to cluster them by angle to decide where to make shading breaks, and some programs may need for it to be specified manually.

Hi Michael,

> ...is there still a "normals" tag in C4D...

That was it. Deleting the Base Tag [Normal] and the aberrations disappeared.

Moreover, I did not follow your suggestion posted somewhere, sometime ago, "It is not necessary to use Riptide to import into C4D." Riptide adds three tags exacerbating the problem. Strip those out plus the normal tag and the Riptide import is fine. But, you are right, Riptide is unnecessary.

This has been about working within the overlap of two modeling apps and how well Moi plays in C4D's environment. Tweaking remains but Moi's mesh is good to go.

Thanks for all the help, Michael.

No problem Leonard, I'm glad that you are getting the results you wanted now!

Yeah with that normals tag still in place, it was basically trying to use the shading information from the original imported mesh which did not match your edited result any more.

Re: Riptide - if I remember right, there is some stuff that Riptide supports that the stock OBJ importer does not... I think it might have been reading in the material colors from the companion .mtl file.

So although Riptide does not seem to be necessary for bringing in the basic geometry, if you want to bring in all materials on a more complex model where you may have a few dozen styles set up in MoI, then it may be more useful.

Michael, it seems every time you help someone out, you expand my knowledge about the subject. The Riptide comments you volunteered explained some of the how and why of Riptide that no other source has provided. Also, no fragmented odds and ends from you; you always provide the full explanation. You are a one and only. Thanks again.

BTW. If you could harvest the nuggets you, and others, have provided here it would make one hell of a manual or six. Coming from you, the manual would certainly be more useful than most.
