Alright, I am attempting to make my own part, and I know how to set up the .CFG file, I am modeling the part in Cinema 4D, but after I modeled the part I got the error (in output_log.txt): ERROR: Collider node found, but no mesh in it I found out this was because I need to create a \'mesh\' named \'node_collider\', I created a separate object and named it \'node_collider\', but had no luck. Clearly I am doing something wrong, could someone give me some help?
