I am working with two different objects that are in very close vicinity to each other.
Let’s say I want to hide part of object #1 while working with object #2 in edit mode. If I switch to edit mode for object #1, “b”-brush the area I want to hide and then hide it, I have to switch back to object mode to select object #2. When I go to its edit mode, the section of object #1 i hid is not hidden.
I tried shift-selecting both objects and entering edit mode, but it will only show the vertices of object #2.
There’s also the mask modifier. Assign the vertices you wish to hide to a vertex group, add a mask modifier to that object and set it to the vertex group (maybe need to press ‘invert’).
