I have aligned my images, and created a mesh (preview and high detail). Now when I do a Mask export, I get a sequence of mostly black frames. As if most of the mask is made from an area that not contains geometry. Sometimes I get a part of the geometry, but it is always kind of a random slice from the mesh.
The settings look good to me. Is this also happening after application reset (Reset RealityCapture)?
If so, would it be possible to share your dataset and project with us?
