Hi Micha,

> * mesh export for rendering in Rhino3D, Cinema4D, Modo.

Well, Cinema4D and Modo are already completely covered - use OBJ export to go from MoI into Cinema4D and LWO format to go from MoI into Modo - that's what Cinema4D and Modo users already use for mesh transfer.

They can already do this without that plug-in - just simply export from MoI to OBJ format and import the OBJ into Cinema4D. Layer assignments are preserved as material assignments into Cinema4D and you are also able to use n-gons and true welding unlike 3DM format.

3DM format is not a good way to store mesh data - it does not really make any sense to export meshes to 3DM format to go to Cinema4D or Modo when the OBJ or LWO formats are able to do it without having the limitations of 3DM format (again, no n-gons or proper welding in 3DM format is possible).

re: "why not go the first step in v3" - as I described earlier, it's because it requires some work for me to produce a 3DM mesh export, and there is not a good way right now to incorporate it into the UI in some normal way...

There are already many steps in place for mesh export since MoI v1 - I've worked hard to have very good support especially for the OBJ and LWO formats which are normally used by people who are exporting to mesh based programs already. Layers in MoI are preserved as material assignments when exporting to OBJ and LWO, and both formats also support n-gon polygons and also true welding.

Consensus is that the Rhino IO plugin for C4D is not worth bothering with. This is because it reads Rhino's display mesh, which is not very good for importing (no welded vertices, etc). It's fine for working in the Rhino viewport. Rhino itself can export OBJ files which are a lot better.

Hi Steve, so the main thing that the RhinoIO C4D plugin can do for someone is to bring over stuff that is not able to go into an OBJ file like lights and cameras.

So if someone has put in a bunch of effort setting up additional stuff like that in Rhino instead of waiting to do it in Cinema4D then that could be useful to have that stuff transferred over.

But yes just for transferring geometry only I can't see why you would want to do that.

MoI does not set up lights or cameras in it, so that aspect of the plugin won't be of any particular use for trying to use 3DM files to transfer mesh geometry from MoI into Cinema4D - that won't be gaining anything and will actually lose functionality, particularly n-gons.
