The 3ds Max dope sheet isn't doing this. It's a 3rd party tool that's creating custom attributes. Check to see what scripts you have installed. In the dope sheep you can go to View > Filters and uncheck Static Values. This should hide them. If you want to delete them you can try this line of script: It may not delete them,…
So I tried the script in listener and it shows "0" attributes found. And unchecking static values doesn't seem to turn them off. My last option is the plugin thing. I guess I would have to go through and delete them one by one to see which is causing the issue. Thanks for the tips!
