Trim Masks

This is a library of node groups to create trim masks for trim atlases with logarithmic distribution in Cycles and Eevee.

What I call logarithmic distribution is the effect of a tile along one direction being half the size of its predecessor, starting with 0.5 as the first tile size. With these masks you will be able to create trim sheets for entire PBR texture sets directly in Blender. Just play around with the examples in the file to get a hang of it!

If you use this for your art and you're sharing results online, please tag me with @narranoid so I can see what you're making! Also, if you feel very supportive, feel free to add the product link as well. :)

Recommendation

I recommend using them combined with the HotSpot Tool of the DreamUV add-on by @leukbaars. Get DreamUV from GitHub and check the Hotspotting feature in the README section: https://github.com/leukbaars/DreamUV
