Mirror Skin Weights

Hey guys, first time posting here. I’ve started using Blender recently and I’m having some trouble when I’m Weight Painting.

Is there any feature that works like Maya’s “Mirror Skin Weights”?

If that’s the case, does anyone knows a tutorial or video of someone using it? I’ve found several kind of confusing aproaches to this topic but with no luck.

here are some links to some info and tips.

i’m not good with blender so maybe there is an easy way to do it, but it’s not as easy as one would think.

Yup it is in there, can be a little wierd https://www.blender.org/manual/sculpt_paint/painting/weight_paint/tools.html?highlight=mirror
