@Kenmo - why aren't you using Modo with Mesh Fusion for your modeling now if it generates the type of model that you need?

Right now you're trying to use a faulty toolchain basically. You're starting in MoI which has no focus whatsoever (not in modeling nor in export conversion) on making all quad edge flow based model structures and then your downstream tool requires only all quad edge flow based model data.

You're setting yourself up for a lot of pain and suffering by trying to force a toolchain together that does not connect together.

You should probably pick which side you spend the most time on (modeling or uv mapping/texturing) and swap out the other side for something that is compatible.

Modo is way too expensive for me.

I love MOI3D. it's very simple to use and produces excellent models. And well worth the money.
I also model in Silo3D and Blender 3.1.

But 3DC is my preferred tool for uv mapping & texturing. I do not do a lot of sculpting as I am more interested in modeling cars, space ships, buildings and other similar hard surfaces.

MOI3D is also a big step up from Sketchup and Form-Z for me.

Sorry I an mot complaining, just asking questions.

Hi Kenmo, I'm sorry I don't know how to explain it any better than I did above. You're trying to combine 2 tools that are each focused on totally different types of 3D model data. So it's going to be frustrating.

May be I don't understand, but if you use blender why not uvmap in blender. It is deals with ngons fine. It's my preferred uvmapping program. I use fbx export over obj, never have a problem.

I only use Blender for modeling. I am more comfortable uv mapping and texturing in 3D Coat especially since 3DC has a built in link for exchanging files & layers with Photoshop. Since I am more of a photographer, I am very comfortable in Photoshop.

I also much prefer 3DC's PBR shaders over DAZ Studio's IRAY or anything Blender has to offer. I also use e-onsoftware's Vue and much prefer 3DC over Vue's materials as well.

I use MOI3D for the same type of models that many Blender modelers go to addons Hardops & Box cutter or Fluent to produce. I have Fluent but find MOI3D much easier and a lot more straight forward.

I do think MOI3D has a place in my car modeling, perhaps not for car bodies but it appears ideal for creating car frames, wheels, tires, engines, car differentials, etc.

My initial reason to get into 3D modeling over 20 years ago was to produce assets to be used in my Vue (e-onsoftware) renders and later DAZ Studio.
