When using the knife tool, if there isn't one already, is there a way to create a shortcut that will allow you to turn the angle constraint option on and off?   Cheers  Jim

This looked fun to model, so I couldn't resist!  I've attached an updated file as well as some screenshots documenting my process.  It may not be 100% clear what I did in each step, but I didn't have time to make notes of all that.  Ask questions if you've got them.  @Cerbera's comments still definitely apply for you. https://we.tl/hRWoa7CK96 DOY-PACK- v2.c4d

here we go...    OK, I promise to burn my mac and only use PC's from now on. The CG gods are frowning on me, itunes is hubris etc.     

Hi, check that your key-frames are set to linear mode.

Currently working on an animation, with a character with sunglasses. The goal is to animate the hair a little bit with wind force. Everything works fine, except the hair comes trough the sunglasses. I've added the hair collider tag on the glasses, looked at some tutorials for the right settings but no good result.   Is there something I forgot in the settings of the collider tag, hair settings,...? In the attachments you can see my settings as reference.   best, T

I don't know about the flipping part, but I assume you also get weird 'lagging' when you play your animation.   When you work with constraints, there is the a "priority" field, it is hard to explain. But in general, you need to put them in the correct animation order, C4D looks from top to bottom in the list, or you can override it in that field.  So stuff that needs to follow another object, has to be calculated after that object it is constrained to.   This MAXON Quicktip explains it a bit better:       

Hi @Rectro, thanks for your comment! I'm sorry that I forgot to reply, I was time-pressed on this and just made a new scene where everything turned out to work well. I think the culprit was that I turned on Autokeying and then turned it off again, and that this somehow caused cinema to believe I had changed position/rotation of stuff without actually having touched anything. If I encounter the issue again I'll upload a scene here.

Hi, I have to rework some animated models for a game, and one of the things I'm doing is deleting several joints from joint chains. When I delete a joint all individual points weight data for that joint becomes unassigned - i.e. black, and I need to reassign it to another joint manually. Is there a way to assign all un-assigned weight data to a specific joint? In all my cases the unassigned weight data (from the deleted joints) should be reassigned to one single joint, so to be able to do this automatically would speed up my workflow a lot.    Also, as I'm getting deeper and deeper into joints&weights, is there any good advanced tutorials out there that covers any tricks I might have missed? I have a hunch that I'm not really making full use of these tools at the moment.   Cheers!
