How to use 3D Materials optimized for Dimension (PBR textures + .mdl) with Substance Painter
Backstory: after a couple years of making do with Adobe Dimension for quick and dirty texturing, I recently took the plunge and am now subscribed to Adobe Substance. I have nearly 100 3D materials that I licensed through Adobe Stock which, as far as I can tell, are only compatible with Dimension and cannot be easily imported for use in Substance Painter (each of these 3D material assets, once downloaded, consist of PBR texture maps and .MDL file - see pic below).

Question: basically, I'm trying to figure out the best way of using these materials with Substance Painter. Is there a streamlined way of importing these materials into Substance Painter / converting them into Substance materials? Do I need to rebuild them as Substance .SBSAR materials using Substance Designer / Sampler?
I've searched high and low online for an answer / workflow for accomplishing this conversion, but haven't found much - if anyone has found a solution or could recommend a good workflow, it'd be very much appreciated!
