cant animate bound joints
i made this cool alien, and i wanna make him dance to a song, but i cant get him to move. im learning c4d thru youtube tutorials, and follow the vids step by step, but mine isnt comming out right. this is what ive done:
create alien out of sphere with extrude, move points etc.
hypernurb it.
use joint tool to make skeleton. lined it up so no bones poke out.
bind to sphere and hypernurb.
weight each joint for what i want it to control.
try rotating certain joints to test the bind.nothing moves when i try to rotate any joint, then i figured maybe i did something wrong, so i opened up a new project, and extruded a cube to make an L shape, jointed, bound, and weighted it, and still came across the same problem. am i missing a step? the videos all had their models work, and i even replicated all the settings shown..

It’s possible that you’re looking at old videos? The character animation has changed considerably over the years. With the current system you need, at minimum:
* Mesh to be weighted;
* Joints;
* A weight tag on the mesh referencing the joints;
* A skin object to deform the mesh based on the joints and weighting. -
yea i get those too when i bind(the weight tag and the skin object
) but when i get them do i have to mess with them? heres the video in case he missed a step or sumthin:
https://www.youtube.com/watch?v=dniWVu55PEc and the bind steps are here https://www.youtube.com/watch?v=dniWVu55PEc and when he does it just automaticly works.Some contents or functionalities here are not available due to your cookie preferences!This happens because the functionality/content marked as “Google Youtube” uses cookies that you choosed to keep disabled.

could it be cuz i got mine hypernurbed? thats about the only difference i can see between what i see and do. but my model doesnt go to automatic weighting, i gotta do it myself, and even after i weight it, i cant move it at all

That could be the problem, depending on how you set it up. The skin object and weight tag should be applied to the mesh itself — not the HN object.
If you can upload the file I’ll take a look at it.

how do i upload it to here?
-
nevermind i figured it out(how to upload on here). here it is, binded from the sternum up, not including hands or antenna. i was just tryna make sure i could create a basic before i got all into it. if you unbind it, rebind and go to the weight tool and youll see what i mean about the not even auto weighting
-
I can confirm that there’s something strange about the file as you set it up. But when I bind it myself it works fine. One thing you do need to do is select the first joint under the root null and change the Bone type to From Parent instead of To Child.
-
exactly what steps did you do to unbind, then rebind it? i just deleted the weight tag and the skin object and tried it again, but still ended up with the same result. and should i change all the joints to be from parent, or just the first one?
-
I deleted the weight tag and skin deformer, selected the mesh and all the joints (but not the root null) and ran the Bind command.
Just the first joint needs to be set to from parent. Otherwise it throws off the position of the rig. The rest of them can be eithe way.
What version of Cinema are you using?
-
r12. and after you hit bind you can immediately start rotating joints and moving the mesh?
