I'm trying to set the XRay parameter of a sphere created with an ObjectPlugin.
However, it is not working in R13, R14 or R15?
Note: Changing the radius in working.Here is the code:

CONTAINER c4de { NAME c4de; INCLUDE Obase; GROUP SETTINGS { BOOL PXRAY {} REAL PPREVIEWSIZE { MIN 0; MAX 1000; STEP 1;} } } -

Some further testing showed that it is working in a TagPlugin.
Could it be that it is not working in a ObjectPlugin due to the fact that the sphere I want to xray is a virtual object? -

Hi Pim,
Yes I think the problem is that the object is a virtual object, I remember
having a similar problem a very while ago. I'll do some research about it.Best,

the node (the gelistnode representing your plugin) has to be flagged ID_BASEOBJECT_XRAY
to be drawn in the XRAY pass or the ID_BASEOBJECT_XRAY of your cached children won't have
any effect. Your code should work when you do add> node[c4d.ID_BASEOBJECT_XRAY] = node[c4d.PXRAY]
to your GVO method.
edit : FYI, you might have to add c4d.OBJECT_POLYGONOBJECT as a plugin flag to your
plugin registration to get the xray thing to show up in your description and therefore get
whole thing to work. If you want to hide it then again you have to do that in your plugins
description.INCLUDE Obase;
HIDE ID_BASEOBJECT_XRAY; -

Hi littledevil,
Sorry, I do not fully understand following lines
"FYI, you might have to add c4d.OBJECT_POLYGONOBJECT as a plugin flag to your

whole thing to work. If you want to hide it then again you have to do that in your plugins
description."I now have this code:
node[c4d.ID_BASEOBJECT_XRAY] = node[PXRAY]
preview[c4d.ID_BASEOBJECT_XRAY] = node[PXRAY]However, the whole GVO object is now XRAY, not just the preview object.
I also included HIDE ID_BASEOBJECT_XRAY;
INCLUDE Obase; was already there. -

What I meant with the quoted part is that without OBJECT_POLYGONOBJECT the xray checkbox
in Obase is hidden by c4d by default ( if I do remember correctly ), so I thought the xray pass
might also be skipped ( which does not seem to be the case from what you have described
in your latest posting ).About the current problem - I do not think there is a way around. I have written recently a little
object plugin replacing null objects. Long story short - I thought I could use the display color to
return splines with various colors to draw some stuff into the viewport and have not to care so
much about caching and speed. It turned out I could not (at least I did not find a way), as all GVO
children always do inherit the display color of the hosting node in the object manager. I did end
up drawing everything myself in Draw(). I think the same goes for the XRAY option, all children
will inherit the nodes settings and their own settings will be overwritten.And then again, I do not know 100% for sure.

Try it like this:

Thanks Scott,
I tried your code, but it XRAYS all virtual objects. and not the want I want.
E.g. I simplified the code to generate a cube with a sphere as a child.
Then I tried to xray just the sphere and that is not working.
XRAY op is xray-ing everything
XRAY just the sphere is not working.def GetVirtualObjects(self, op, hierarchyhelp) : cube = c4d.BaseObject(c4d.Ocube) sphere = c4d.BaseObject(c4d.Osphere) sphere.InsertUnder(cube) sphere[c4d.PRIM_SPHERE_RAD] = 150 p2 = op[c4d.P2] #Get the value in this gizmo if p2 == 1: sphere[c4d.ID_BASEOBJECT_XRAY]=True else: sphere[c4d.ID_BASEOBJECT_XRAY]=False return cube
