The Start-to-Finish MSFS Livery tutorial - Blender texture painting using msfs2blend
N.B. - Many people are reporting this doesn’t work with the TBM930, your mileage may vary
EXTRA VIDEO 1: Discussing how to paint rudders (every aircraft is different, I show the A320 and the grand caravan but not how to do stencils that go on both the tail elevator and rudder)
EXTRA VIDEO 2: how to stencil across 2 parts at once. It won’t always work for every plane, but I’ll just be directing you to this for you to learn from now on. You need to adapt it to your plane/part combination, and there are too many potential combos for me to teach you them all.
