“Straight on the surface” I meant the pivot point of each object would be on a surface, not behind or above. I did it as it’s suggested in that thread.
Depth slider don’t make each object imbedded equally on my side. You have to actually adjust it for each mesh separately.
I am not sure it depends on dimensions. For most objects it works just fine as it would be pivot based most of a time. But sometimes they come hovering or buried. I can’t find any specific reason.
Just tried to merge all subtools into a single one and then split them all again by hand so I guess they should share the same pivot. No difference. Being used separately with a single insert mesh brush they are ok and always on a surface.
ps. There is a Pistone mesh in the IMM ind.parts brush. That "pistone"and “Philips type1” also come always hovering while other parts are ok. Guess it’s someting wrong in the meshes itself
