Can't get components to spin well, anyone?

Postby dayvids on 07/14/2012, 10:09 pm

Hey guys, I've been crusing through the blend swap site, just pulling down whatever models I can find and exporting them out, but I can't seem to be able to animate things that should be perfectly symetrical.

Is there a way to force compoenents with the same materials that are symetrical to animate around their center? Any help would be appreciated.

Thanks!

If things aren't spinning symmetrically then the anchor point probably isn't perfectly centered. It's probably something that would have to be edited and fixed in the 3D software. Then you can bring it back into Element and animate.
Just trying to learn!

I tried that, I put that anchor point smack dab in the middle (using blender) and it was a zero joy sort of situation where it just spun off center still. Maybe something about the way that Blender is exporting it?

Anyone else using lender been able to get a good spin?

I was finally able to get one that would spin well, but not terribly...

I had some problems creating a helicopter (seperate rotors). It seems that all elements/objects share one central pivot point of the biggest object in that group. only way I could solve it was to save the rotors as seperate objects.

same here.

Can't get the "seperated by material" objects to have their own axis.
they always seem to inherit the axis/center of the entire mode.

I am somewhat inclined to think this is an issue with blenders OBJ export. I could be mistaken, but I think so...

Ok I had the Blender spin issue, with things wobbling.
Never used any 3d software, including Blender, before I started using Element3d, so my Blender tips may not be the easiest way, but here it is....

The 3 things I did resolve it (assuming rotation on a coordinate axis, not a random line!)
Obviously delete all meshes that arent part of what you want to spin....

1) Make sure all (symmetrical) objects that are on the spinning axis have 2 zero coordinates, eg 0,0,10 (not 0.01,-0.13,10)
2) Make sure all large "mirroring" objects are mirrored about the axis. Eg if one rotor blade is at 10.3,5.2,0 then the opposite will be -5.2,-10.3,0 for example, not -5.1,-10.305,0
3) Finally add a cube centred on 0,0,0. Then scale it up so it encompasses all other objects. Assign it a unique material so you can hide it in Element3d

Now export.

Not sure which steps were mandatory (eg I vaguely remember skipping step 2 on some)

This worked for me. Here is my first example vid after doing a..wait for it...chopper.

Hope this works for you!
