CAD, Alias, Rhino3d, SolidWorks, CATIA, and other NURBS proffesional 3D software do not export in triangles. Are much better tools than Blender and Maya becuse make good reflection surfaces and has more control on the surface but do not creates triangles FBX.
We need a CAD IGES Importer and convert to FBX. That alowed to make UV unwrapping, flattening/unrolling of all UV meshes and tree merge fixing of the objects. To be rebuilt the 3D object to triangle meshes. So that we can use better assets inside Substance Painter and then return back to that particular software or send it to Unreal or Unity.

Allegorithmic’s Modo integration provides the useful "Bake to Disk" function, that allows saving baked image files of each effect layer to disk.

I’d like to have a feature "Bake to new Material" that essentially bakes the images clips to disk in the first step and secondly bakes a new autonomous material in Modo:

• The effect layers of the new material should be linked with the baked image clips
• The material should inherit the properties of the original material
• It becomes an independent Modo material without pointing to the substance integration

This feature should be available for all material types in Modo (default, Unity, Unreal, glTF).

Currently you have to this manually which is very time consuming.
This feature would open new possibilities for the workflow and make it easier to export textured meshes.

DAZ Studio Pro is a(n amazingly free) figure creation (and animation) tool made by DAZ3D, utilizing paid content to create 3D scenes and figures. It uses the Iray rendering engine. It normally uses pre-made texture libraries created by and available through DAZ3D's online store, but it also allows end-iusers to create, use, and even package and resell their own textures, shaders, materials, and libraries. That's where Substance Designer (and Painter) could step in. If there was a Substance plugin for DAZ Studio, we could drag and drop our substance files into DAZ, and have them instantly converted into DAZ Studio style shaders. The DAZ Studio software itself is free, and their Dev Kit comes with it. Their scripting and C++ development API is wide open. As is the documentation for it online. Their shader mixer is pretty straightforward. There are no roadblocks to doing this. I think it'd be a wonderful idea.

Modo introduced its glTF material shader this year and I’m looking forward to a "Substance in Modo" integration with glTF material support!
Currently this is a missing link in the glTF workflow.

It could be implemented similar to the existing Substance support for Modo’s Unity, Unreal and default material shader.
Modo’s glTF materials however require a single image clip with channel-packed maps for Occlusion, Roughness, Metalness (ORM workflow).

In the course of the ORM workflow, it’d also be nice if the "swizzling" option is set to active and to the corresponding RGB channel in the glTF Material when creating an Output layer with the plugin. But that’s just a detail.

Rhino3d or .3dm files are the only way / best solution to flatten / unroll a surface for my needs in card modeling. But when converted to a rhino nurb to use all the flattening/unrolling functions all UV information is destroyed and needs to be rebuilt. Using anything else such as pepakura designer will work but the quality of the end results are poor to say the least. Once the object is flattened you are extremely limited and have to resort to a vector program to texture your card model. The best way is to paint in Rhino3d on the rhino nurb, flatten the object, then export directly to print ready format. We need to either be able to read a .3dm file in substance painter or have a 2 way bridge to Rhino <> Substance Painter
