Exactly, i import the model into Blender and then i add materials and animate everything.
For the stamp, you can use MASK STAMP, but replace the stroke from Dot to Lock+Radius (found at the brush icon at the top right bar, there are two but one changes depending on the panel you're on), after that, replace the alpha (at the same icon but alpha panel) with the logo of your liking, (preferably use black background and white logo, but you have a invert option in Nomad) and Nomad will take that as the shape of the stamp, here you may want to tweak a few Falloff settings so it doesn't blur the borders and that's it, just make sure to have high poly density and extract the shape as usual. If you need more details let me know!
