What about importing from Blender and exporting to Blender? The scale is 1:1 ?

it's me again lol. You bake as emission channel (Color) and you activate the Normal layer too (set as Bump). For the AO effect, you use a Solid Color Layer with a mask that use the previous Emission image as the mask. I missed something else?

oooh ok I already know the dude's products, so you are using his heightmap brushes and with Ucupaint you bake them into the bumpmap channel. Correct?

Hi, how did you made those grayscale textures?
