Modeling a prop that has a rotational point that is not its center.

pfunkyfize

Hi all,

I've modeled a door and rigged it so that it rotates on its hinges along the Y axis. Is there any way to model the door in Hexagon to get the center/rotational point to stay on the door edge along the Y axis and actually bake it into the OBJ. I see that in Hexagon you can change the rotational point of the object but it doesn't seem you can make that point be the center(?) or is there?

Thanks!

I notice in DAZ that some door props made for Poser come with the rotational point where door hinges would be expected and I am curious how to imitate that. The door itself can be selected in the scene tab and in the parameters tab you can open the door directly. In DAZ, so far i have only been able to make a child bone for the door 1 level below and I have to select that to open the door and not the actual door itself.

DAZ studio does not support local space pivots only world space so the door would need to actually load at the 0,base on y-axis,0 coordinates on the hinge then be parented to the doorways as a smart prop.

people get around this by rigging the props with bones and the doors unwelded mesh

There are some things like shading domains you have to do first, any problems let us know

Not true. It it true, as far as I know, that chnages have to be made in DS and the item saved as a scene or native asset.

Okay, let's make it clearer. D|S does not support importing local space pivot in an .obj.

Thanks all, so I need to do something with the prop inside DAZ and not to expect it to transfer from Hexagon to DAZ. Got it....

Thanks! I have been using the MYDART rigging tutorial and it seems to be the same way JG is doing it and how I've been doing it. I am happy to know that this is the usual way of rigging hard items in DAZ and that it can't be done in Hexagon so I won't have to waste time finding a sHexagon solution to this. Thanks all!

Have you got a link to the MYDART tutorial ?

Lets say you made the door in Hex and send it to DS using bridge. Next, select the door is scene tab and go to Tools menu - Joint Editor. Two (green and red) gizmos will appear. Position the green one in top corner and red one at bottom corner. Switch to universal manipulator tool and now Y rotation parameter is your open / close door rotation. Save the door as figure/prop (File - Save As - Support Asset - Figure/Prop Assets...

If the task is not rigging but to move the origin point:  there was a script  "Move Origin" by Delta x1 which does the job quite nicely, and there is a script by mCasuals "mcjcangeorientation" to set the rotation axis at https://sites.google.com/site/mcasualsdazscripts3/mcjchangeorientation ; (Thanks to mCasual for all the gorgeous scripts).

I think both scripts are mentioned in other Daz discussion. Both work well and there might be other scripts which will have similar effects.
For me rigging is a great method to move parts of a complex mesh-system,if you have only something like a single door I feel that moving the point of origin is quite more satisfactory.

Nice days and nice renders

Sorry, I missed this. As far as I am aware OBJ does not support recirding local space pivot of an object, at least in general (I suppose some applications may have a custom modification of the format for their own use).
