I would like to create a dynamic door that is able to resize but keep the height of the top and bottom bar, same for the width of the left and right bar.
What I have done so far (in Blender) is to create six vertex group (H_TOP, H_MID, H_BOT & L_LEFT, L_MID, L_RIGHT) and associate them with six bones in one or two armatures.
If I have two armatures (and consequently) two modifiers, I am be able to scale only H_MID (only z direction in blender) and L_MID (only y direction in blender) and get the expected result. The problem is that if I export the file to Babylon, there are two separated skeletons (two modifiers), but the door can have only one, and I can only H_MID or L_MID (depends on the order of the modifiers)
If I try to merge the two armatures into one (and consequently only on modifier) the weight seem to be normalised (even though they display 1,1,1,1) and the door gets distorted.
Thank you per advance,
