Mari seems to have a few gotchas. Anyway, I managed to export a diffuse texture out of it, to use in Vue. Painting was a bit sloppy, not sure how to fix that. Probably by selecting faces but selection is one aspect of Mari I haven’t quite mastered yet. Not convinced at this stage that it’s actually better than painting on the UV layout in Photoshop.
When I did the Environmental Texturing workshop with Leigh van der Byl she mentioned that she’s now using Mari more, and that was back in 2013. Anyway, it’s early days.
