Windows 10: 3D Builder saving as .obj file with blank .mtl file - Textures/colors not saved?

I'm trying to make simple 3D objects with 3D builder. I have no trouble saving as .3mf but I need to save as .obj. When I do that, the .mtl material file that goes with it is blank, so the textures and colors I put on it are not saved. Is there a solution to this? How do I get the proper .mtl file?

3D Builder issue. No textures

Hello

I have created a .obj file in photoshop. I have the texture files and the .mtl file but 3D builder does not ask for them when I import my model, giving me a blank model. How do I tell 3D builder to use the .mtl file and textures?

Many thanks

Exporting OBJ files using 3D Builder

Is there a way to simplify the OBJ export feature in 3D Builder for Windows 10? At present I’m importing GLB repair and export. When exporting as OBJ I have many file save prompts - first OBJ, then MTL, then literally 100s of PNG baked texture files. Is
there any way around these 100s of save dialogue boxes please! Here is a video link demonstrating this issue and the many save screens I’m trying to avoid -

How to make Windows 10 3D Builder automatically load .mtl material when opening OBJ 3d files with textures?

When I open an .obj file in Windows it helpfully uses 3D Builder, and it also "understands" how to load texture files.

The way that wavefront obj 3d files work is that they use material files to define reference texture files.

This is a really simple case where at least three files correspond to one 3D asset. An obj 3d model file, a nearly trivial mtl file that references the texture, and the texture file which is a jpg.

All of these files are in the same folder.

When opening the obj, 3D Builder does not realize that the mtl is in the same folder. And it prompts, requiring us to "Proceed" to search the filesystem for the mtl and then subsequently all referenced image files.

THEY ARE ALL IN THE SAME FOLDER!

The flow is slightly better when using the 3D Builder's Open -> Load Object menu, this remembers the directory that you opened the .obj from, at least, but I have to manually navigate to the .obj file to begin with in the UI as well.

I wonder if there is any configuration that can help improve this horrible workflow. I guess maybe if the obj/mtl files used absolute paths to reference the file it may work the way I want it to.
