Hm, unable to reproduce so far. Any chance the submodules of your armorpaint clone did not get updated? (eg. both git pull origin master and git submodule update --init --recursive are needed)

[jcostello]

I will try and let you know

[luboslenco]

How do you create a fill layer?

[jcostello]

I drag the material into the mesh.

I deleted armorpaint directory and clone it again and update modules and seems to work but I got the same error trying to delete a fill layer. I will try to reproduce

Nice, was able to reproduce with the height map! Pushed a fix at https://github.com/armory3d/armorpaint/commit/58800f77f847f1805651e9e6b126fff22a236077. Thanks for patience.
