I am very new to blender and have a model (an .obj file) where I want to remove some groups. Removing the groups are no problem, but when I then import the new file into the program where I'm using the model, with the groups removed, the resulting bounding box is still the same as when the groups were there (the groups are at "the end" of the model, so the size should be smaller).
It's like if the groups are still there, taking up space. I have removed the groups by clicking on them in the scene and clicking "Delete". In the resulting .obj file I can find only the two groups that are still there. But for some reason the bounding box volume is the same as when the groups were there. Just to be clear, the bounding box is wrong in the other program I'm using. I can't find the bounding box in blender.
I have also moved the pivot point by following these instructions, and setting the pivot point to the center of the model (I think), by doing Tools -> Transform -> Set origin -> Set origin to center of mass (surface)
I have received these instructions from someone who has removed groups before, but I can't find what the last step means.
- remove groups
- move pivot
- apply all transformations and rotations
