also, be sure to check all of your pointers.. for example, if you have.....

BaseObject * op = BaseObject::Alloc(Osphere);

make sure you have

if (!op) return False; or something like it.

ye, i'll try the thing with GePrint.. used it before. Sometimes i just dont see the wood because of the trees

pointers are all checked. the strange thing is that it just happens when rendering. the object itself works and i can convert (using c) and this works too... only rendering crashes...

cheers,
ello

btw, how can i know in an object plugin if the render has been called??

In GetVirtualObjects() check the HierarchyHelp's GetVFlags() method.

ok, i managed to find what is causing the crash now..
Here is the relevant code:

  
PolygonObject*  baseMesh = static_cast<PolygonObject*>(bc->GetLink(BASEMESH,doc));  
if (!baseMesh) goto Error;  
...  
op->NewDependenceList();  
op->AddDependence(hh,baseMesh); // <--- this is causing the crash

can someone point me on how exactly i can check if GetVFlags() contains VFLAG_INTERNALRENDERER or VFLAG_EXTERNALRENDERER ?? it returns 18(if rendered in editor) and 20 (if rendered in the image manager) but if i try this:

if((hh->GetVFlags()!=18)&&(hh->GetVFlags()!=20))op->AddDependence(hh,baseMesh);

it still crashes...
if i comment that line out, it doesnt crash anymore, but i need that line for performance reasons

thanks and cheers,

GetVFlags() returns a bit mask. You have to mask the bits you want to check (single & and single | operator).

  
if (GetVFlags() & VFLAG_INTERNALRENDERER)  
{  
 //editor rendering  
}  
  
else if (GetVFlags() & VFLAG_EXTERNALRENDERER)  
{  
 //external rendering  
}

thank you! than it must be something other.. if i use the following line and render in the editor, it crashes:

if (!(hh->GetVFlags() & VFLAG_INTERNALRENDERER))op->AddDependence(hh,baseMesh);

if i comment the whole thing out, it renders with no problem.

any ideas what could cause this strange behaviout? why does commenting works, but disabling when rendering doesnt??

and to make it even more strange, rendering in into the image manager works, but rendering in the editor doesnt work:

Bool editing = TRUE;  
if (hh->GetVFlags() & VFLAG_INTERNALRENDERER) editing = FALSE;  
if (hh->GetVFlags() & VFLAG_EXTERNALRENDERER) editing = FALSE;  
if (editing) op->AddDependence(hh,baseMesh);  
else GePrint("rendering...");

any ideas?

Can you post a simplified version of your GetVirtualObjects() method that shows the problem?

edit: i updated the code and with using the GetVFlags, it works now, so i guess it must be something other in my code where i am creating the clones (i'll double check the whole stuff again)... nevertheless if there is something generally wrong with how i use the dependeceList, it'd be great if someone can point me to it.
