Plugins + Scripts Blender to Substance UV Helper for G2F

Helps create a model for painting in Substance Painter that looks closer/matches the look in VaM.

This should remove the need for the most tedious click-intensive part of importing to substance.

We're going from this:


To this via the script:


Tested with Blender 4.3

Export OBJ from VaM:


Drag the femalecustom.obj into Blender scene:

• Check Split by Group
• You could also try using the _skinned.obj to get closer to exactly the shape you see in VaM, I have not tested that all the way through.

Navigate to UV Editing Tab, Click New Image:



Pick a resolution to match your textures, chose type UV Grid



At this point you can enter edit mode with your model selected and select all faces to see where they are on the single UDIM tile we start out with.

Find this tiny arrow to pull out the Image tabs.



Set type to UDIM Tiles under the Image Menu



Create tiles for 1001-1008



Open the Script Tab > New > Paste the attached Python script: remap_uvs.py

Then make sure to select your model in the 3D view in Edit Mode, Run.

You should see your UV's on the Tiles specified in the config.

The last step to get into Substance is to create a combined material based on the UV assignments:


(Still a few more clicks, I couldn't get that automated)

Search the Hub for guides on Blender to Substance to Fill in the gaps after this step if you need.

Hope that saves some time & energy with your painting!
