Thanks, that seems to free resources.
The way I figured it, with voxels, is to import from the folder (startup voxel option) and pick one of my meshes, then universal scale up to a specific number (150), select close meshes and hit apply. Then add another branch on the voxel tree and with 'param' options still visible, select mesh, pick another .obj, apply. Repeat and rinse. Every mesh will pop in correctly. Then I can enter the retopo room and go at it.
Is there any way to pick a less bright shader when importing .obj "as reference mesh"?
Thanks very much,
Brandon
