Magically Inflaiting Tire
show user profile  Aurel
Can someone PLEASE explain this to me? I've been using 3D Sutdio Max since I was 14 (well over a decade and a half) and I simply don't understand what the fuck is going on. I'm currently in v 2015, I have a VERY simple 3D model of a car, I've re-set Xform and used a skin modifier, gone through and zeroed out all of the bones weights (why isn't it like this by default?) and am going back through and assigning them by hand. When I assign a value of 1 to some parts, they do this. It is infuriating!

Is it an imported mesh or taken from another source?

If all else fails, use Attach ( inside the Edit Geometry rollout thing of an Editable Poly ) to attach it to another poly object ( one with all the verts deleted first so it's empty ), then go from there.. I had a similar problem recently skinning an FBX imported from C4D..

"gone through and zeroed out all of the bones weights".. did you freeze transforms on them? I havn't seen this in a while, but I'm pretty sure it's because xyz scale is not 100, or the bones already have animation on them?

-or- something in the bone hierarchy wasn't reset/frozen

Thanks for the quick responses guys (Love these forums).

The model is an original work of about 30 seconds. I'm making tiny cars to be crushed by mechs in my UE4 game.

I built the parts separately but attached them to the body which had no transforms applied to it, so I thought I'd be fine. The other doors and tires worked fine, but then I got to this one which apparently decided to inflate. This is after re-doing the rigging a few times to prevent said problem using a reset Xform.

I'm familiar with the trick you mentioned ScotlandDave (thanks to these forums!) but thought I'd be good since I didn't apply any transforms. My god the Skin modifier needs some love. Has it been touched since the DOSS days?

Digs: I've forgotton what 'freeze transforms' is. Please remind me. No animations on the bones yet.

alt right click u can freeze transforms, zeroing out transform data (it will erase animations on an object and remove any constraints, fyi) - i just tried to recreate your problem but i can't get it to happen - im using max 2016 with sp1 that included some bug fixes and features to skin mod, but yea, no luck recreating : ( will be happy to hear the solution

I'm not sure exactly what it was, but something has fixed it. I wasn't aware of the freeze transforms thing Digs, so I think that might have been it. I did that and re-ddi the skinning from scratch (which was doable in my case because of how simple this project was)

Sorry for flipping out, but sometimes 3DS Max seems to just lose its shit for no reason at all, and I have nowhere to turn but these forums. I very much appreciate the help, as usual guys. I wouldn't be where I am now without the timely and knowledgeable help from these forums.
