[!!HELP!!] Weight Painting Mirror Tool overwrites bones

[suenesun]

Hey guys,

I have a major problem with the Weight Painting Mirror Tool: 

When I fix the Weight Painting on one side of my character and try to mirror it with the Weight Paint Mirror Tool, it overwrites the bone-dependency of the mirrored vertices from the left bone to the right bone and vice versa (I don't know how to describe it better).

I don't know what I did wrong: I used the Bone Mirror Tool to mirror the bones from left to right. And followed @paulneale s tutorial for the rigging of the whole body (except the face). I also resetted the xForm.

I also had some problems with the rigging process of the right arm. The FK_System is weird. When I aligned the shapes they somehow stretched. I thought this was normal so I proceeded to continue the rigging. Maybe this is the problem? 

I wanted to rig the right arm again, but I have the same problem. How do I fix this?

I hope somebody can help me with this problem. I don't know what to do.

I attached the current file ( I know that I need to rename some bones ).

I don't have time to look at the file but I'm going to suggest that you watch the video again and make sure that you have checked every step. 

Why are you using those old bones and not the Max bones?

Look at the rig in the left viewport and ensure that you only see one arm and one leg. This would confirm that they are right on time of one another and perfect mirrors. 

Confirm that the mesh is mirrored in the same way as above. 

Convert all the bones to Max bones, this can be done via Max Script and a little know how. 

Lets see an image of the mesh with the mirror mode turned on in the front viewport.

Just having a look at the file. Just to note, the Skin modifier works exactly as it should. 

Your character is 175 Meters Tall!
None of the arm bones are mirrored, they are all over the place. 
Character mesh is not mirrored.

Thank you!

I will fix those problems first and then mirror the bones with the Bone-Mirror-Tool. I hope it will work.

If you do everything correctly it will work exactly as it should. You can't make a mess and then expect the computer to sort it out for you.
