mesh changes

[bgarneau]

Is it possible to make edits to a mesh and re-import geometry changes in substance painter 8.3.0, at all?

This was possible in earlier versions

Basically, I want to take an existing model, an do a damadged destroyed version.

Thanks

Hi @bgarneau,

I've delete my previous message to avoid spreading misleading informations.

Here, Substance Painter uses three elements to reproject the textures correctly:

1. The brush strokes (all the strokes made in the viewport are saved in the project file).
2. The camera position of every stroke.
3. The bounding box (which is basically an invisible cube which encases the entire model)

When you reimport a 3D model, Painter takes the first stroke made in the project, and based on its camera position reapplies the strokes on the bounding box. It then repeats this process for the second stroke, the third, and so on.

The great thing with this workflow is that UVs are rarely an issue for reprojection, even with UVs that are strictly opposite – though this isn’t the case for masks made with UV islands, or strokes painted in the 2D view. Therefore, if your masks have been made with baked maps, or have been painted in the 3D viewport, everything will work as it should.
