The instruction "c_updatehull" only works correctly in the "frame" number 1 in the other states of the animation is displayed incorrectly as I show in the picture, someone can tell me the reason for this?

Download the newest update, there was a bug in c_updatehull in the last new update.

I have the latest version of 3dgs 7.82.2 e tried it with another model but feel the same way, you mean download a beta version?

7.82.3 is the newest!

in the download area do not see that version, you can provide me a link? thank you very much, I have trouble navigating the forum for my low level of English.

this should be the newest version

yes,that's the version I have, according to my program registration is "7.82.2". Used directly "min_x/y/z" to mark the boxes, is the only solution, thanks anyway.
