Maybe, but in the post above..
"...SP ran the path, threw the errors as per log file above invalid preset artistic1 etc....
The shelf shows the alphas, procedurals generators etc... but NO brushes, particles or tools. No smart materials either, even though they DO exist in;
C:\Users\Ewol Drive\Documents\Allegorithmic\Substance Painter\shelf\allegorithmic\smart-materials..."
At this stage I have started Sp1.5.7 and it's running as I can see the alpha's etc.. but there is no brushes...AND this is with items in the program files area, not in documents.
Also whilst I don't state it. In the post ...last ditch attempt...
I have SP running as again, I see the the alpha's generators etc, as mentioned, but they are in program files not documents..
Now just to offer some more..
I have SP 1.3.1 installed on my surface pro that is running Win10. It sees everything, that is alpha's, generators, brushes, tools, particles, smart materials, all shelf items! and these are located in the users/ documents/substance painter/shelf/allegorithmic, OK, it crashes a bit, but why does the shelf work? Unfortunately 1.3.1 does not have an ability to see the directory path in settings, so can't confirm what's happening there via SP on the surface pro.
What I've done now is recreated the EXACT same directory layout that exists under the surface pro with SP1.3.1 moved the files into these. that is the shelf directory is ;
C:\Users\Ewol Drive\Documents\Substance Painter\shelf\allegorithmic. It still will not show up the brushes, particles, tools, smart materials. Even though with the surface pro, SP at ver 1.3.1 the same directory structure will.
Personally I think there is some lingering version identifier somewhere that is telling 1.5.7 that the data in the shelf...//presets is wrong and it throws those errors and does not display the items. As at this stage, the ONLY way those items in the presets exist is via the downloaded installer. Whilst I have moved them, as discussed above, they have not been copied from an external disk or other older source.
