How to make a geoset disappear when some animations are played

[Rex.]

I recently saw a model. Like a peasant. TWhen the peasant walks, the gold bag disappears.
How to do the same thing to the other models, like making the geoset disappear in specific animations with Mdlvis only!

Open the model , press F3 go to anims, select your animation and then press the visibility butten below the geoset list. Now set yor visibility.
