SPTool – Masked Alphas_By JROTools



Have you ever used alphas to add details to your substance painter projects? Did you notice that adding the details took 10 minutes, while masking them out and adding materials to them took hours?

This substance painter tool lets you add custom masks to use together with any Alpha, so instead of having to mask out details for every stamp you make you can now create a mask once and use it infinite times.

Included is also 30 Alphas with masks, so you can try it out right away as well as use them in your projects.

Update – Another version of the tool has been added which works with older versions of Substance Painter, 2017.1.0 and up.

 Info about file names, JRO is a short for Jonas Ronnegard and is added to make it easier to find, at the end of a brush it can say in or out, in means that the alpha is meant to push into the mesh and out means it’s supposed to push out of the mesh.

 The tool can be a bit heavy on low spec machines, best way to make it faster is to run the project in a lower resolution while stamping then increase it at export. Also make sure to turn off any GPU heavy processes before launching such as Photoshop or substance designer.

 Tool comes in two versions, one for substance painter version 2017.1.0 and up, and another version for 2018.2.1 and up.



Since this is a tool where you can use any alphas I think this is a good opportunity for other alpha creators to create masks for their own alphas and include them when they sell or share them, so for anyone interested this product will be available for a 25% affiliate, so if you want to link to this tool please contact me on facebook and I can set you up.
