Is there something I need to do before I close out a scene with MassFX or has anyone experienced this issue? I’ve set up my geometry, in this case its boxes, assigned a Dynamic Rigid Body, set as a box. Assigned Rigid Constraints to the items that need it. Save and close, come back to re-open the scene, all of the Rigid Bodies and Constraints are reset to a fraction of the size. So ultimately I have to go back and click on each part and click the Regenerate Selected in the Modify Shapes section to get the original shape back. This happens everytime I close and re-open the file.
