How constraints Z position in 3D world

[hungseparate]

Hi,

Yes, this solver is set to 2D mode. I had no issues replicating the setup in the video, by using a flat mesh and binding a 3d model to it.

Can you give more details? What problems have you encountered? What did not work well for you?

Tks for you respond, look like its my mistake, i do it again in you demo scene and it working fine, may be i did some wrong setting !
