Some thoughts and considerations for improvement In general, I think it is a good idea to have such a tool to serve as a 3D viewer and segway to 2D tools, and especially to integrate some 3D processing (not creating) into Photoshop. And initially, that works very well. Dragging a 3D file into the Photoshop canvas, getting a Smart Object layer, which can be opened, viewed and slightly edited in this Substance Viewer. Kudos for that integration !
Viewing and/or (slightly) editing 3D files using the Substance Viewer as a stand-lone tool, is less successful.
The file opens in the 3D view, stating I can "Freely move around..." Well, I tried to click and drag anywhere, but nothing happens. Ah, I spot an option in the corner of the canvas, to set my device. Should I pick 2 or 3 buttons, or trackpad" ? I have a Mac with a no-button mouse. What setting do I use now ? And as I tried to switch to trackpad, it couldn't honor my personal settings...So the device settings and gesture clues are quite clueless and useless for most Mac us
