Sorry, for create another topic about this, but my old one, stay unsolved:
forums/viewtopic.php?f=36&t=28238&sid=9 ... e835a73bbf
Still, after a year of tryings, I am close to solvation as never. I am abondon hopeless idea, to create turret by my self, so I am start exploring already exit turret&vehicle temlates. Most understandable, and suitable for my new tank model, it's UT-AT, maded by Darth Duck. So, I import his model, and start one by one replace his model parts to mine. As you can see, it works fine: Till, I replace UT-AT turret, to the turret of my tank: So, "hp_fire bug" is appear, and now, I know for sure, it's realy not connected with hp_fire node, becouse I did not change it. I am use the same odf, same msh.option, same hierarchy tree, even the same name of the turret model: "turret_top". The only difference, in turret mesh, by itself. Seems UT-AT turret, was freezed in the center of DummyRoot, and after that moved to correct position. I am do exactly the same, by clicking Transform>Freeze All Transfoms. Perhaps, it should be freezed by some other way, or edited by somehow else? Please help.

Darth Duck didn't have anything to do with the UTAT source files according to the readme.
These offset issues usually happen when you don't do things in a specific order. Move your geometry into basepose position and freeze all transforms first, then create your hardpoints/bones and position them, finally, use the Explorer to set up your complete hierarchy. Test the hierarchy by selecting and rotating your yaw and pitch nulls to make sure everything follows as intended.

Oh, my mistake: seems I looking in to te other Readme.

Thank's, I will try what you say.

-Edit

Yes, I think it works!
