View Full Version : Made Bones, but Can't Make Mesh Move

Hi Everyone!

I'm banging my head against a wall; I'm hoping that I've missed something simple. I just can't seem to make my bones move my mesh at all.

Here's what I've done so far:
- I have the object open in Modeler and drew the various skelegons for it. I made sure the skelegons were in the same layer as the mesh.
- I named the top two skelegons 'Head' and 'Upper_Neck'
- Created 2 new weight maps named 'Head' and 'Upper_Neck.' Each one has a series of points in the mesh set to 100% (They're glowing red when I view them through the "Weight Shade" setting while the rest of the model is green.)
- I clicked on my 'Head' skelegon, and then clicked on Skelegons>More>"Skelegon Weight..." In the box that came up I typed in "Head" as the name of the weight map. (Then did the same with the 'Upper_Neck' skelegon & 'Upper_Neck' weight map.)
- I saved the model and switched over to layout where I loaded the model.
- In Layout I went Setup>Add>"Cvt Skelegons" The message says 25 bones created.
- I note that Setup>General>"Enable Deform" IS on.
- I click on the Head bone, open the properties panel, and click "Use Weight Map Only." Strength is set to 100%, and I doubled checked that right weight map was listed next to "Bone Weight Map" (I also did the same to 'Upper_Neck'.)
- Now when I select the Head bone and try rotating it... nothing happens!!!

I've spent the past several hours trying every different setting I can find but nothing has worked. I've gotten the mesh to deform, but not using the weight maps.

Can anybody tell me what I'm doing wrong?

Read up on resting bones. That has to be done.
And make sure they are active.

I just finished searching the Modeler & Layout documentation for "resting bones" but I didn't get any results. The only thing I could find that seemed close was resetting the resting positions of bones if you're doing Motion Capture.

Could you maybe give me another hint? or point me to a good source of info about them?

Thank You!!! :)

Hold on... I think I found something on page 327 of the Layout manual. From what I'm reading it sounds like I have to "rest" my bones before they can be used, but I'm not sure how I do that. Is it something in the bone's properties panel?

I'm trying again... this morning I clicked on "Rest Position" and "Rest Rotation" in the Properties panel for my "Head" and "Upper_Neck" bones, then clicked "Ok." I reloaded my object into layout and did this right after I converted the skelegons to bones. Also I double checked, "Bone Active" has a check mark for both of them.

My mesh still isn't moving though.

I also notice that if I set the "Falloff Type" to Inverse Distance (rather than Inverse Distance^16), then my mesh will move, but it's very distorted, as if the bone wasn't using the Weight Map. Any ideas? Did I not set the rest position correctly?

I don't have the manual with me to point out where to find resting bones....

But this should help you.

Select a bone of your mesh, with the middle mouse button made a marquee that enclosed all the bones of your character to select them quickly.

Press 'r' on the keyboard to rest them.
