An issue with Maya's weightpainting

Slapunas

Hi Polycount,

I was looking for thread like this and could not find anyone facing same issue so i'll post this here.

I am quite new to rigging in Maya and this probably is something really stupid that I did not noticed but all my weight paints get removed after I deselect the joint or toggle the painting on another joint.



It is really frustrating as I can't find a way to save my weight values.

Any help or suggestions would be greatly appreciated!! THANKS

I'm no Maya expert, but it looks like the viewport is applying shading to the model when you deselect the joint. Can you set the viewport to show the model without any shading?

Can you set the viewport to show the model without any shading?

that's not shading I am showing there. Its a weight paint values displayed on the model in black and white.

Painting weights in Maya has been historically buggy for me, especially with values over 1 and randomly re-assigning values for no reason.

I found I encountered fewer oddities if, before I began painting weights, I assigned all vertex weights to the root joint (100% influence) and made sure there were no stray values above zero on any other joint. This is easily accomplished using the Component Editor.

Note: Maya LT does not come equipped with the Component Editor, unless it was renamed...

Hope this helps

Thanks for replies guys. Unfortunately I still cannot figure how to make it work.

Hey, I've had issues like this before. The solution, most of the time, was one of these two things:

1. It looks like some skin weights are locked which is why you can't add influence from them to the foot. Try to unlock them inside the paint skin weights tool:



2. Make sure 'Maintain Max Influences' is turned off. This controls how many joints can influence one skin weight. Also "Normalize Weights" should be set to 'Interactive':



Hope, this helps.
