I've got a referenced character with a character set and clips that has been instanced to a particle grid. I'm trying to get a certain clip to play when an object (psphere1) gets within it's range. However I keep getting this error, and I have no idea how to fix it. I've tried looking at Maya's mel reference, but it isn't helping. Hopefully someone has an idea of how to fix this.The error I get is:
// Error: Must select a single character or a clip library. //
