Can I change a superclass for an node? I’m making a basic mesh object but don’t want the user to ever convert it to something or make it renderer.
I guess what would be nice is make a object then change it to a helper. But have it in the “Create Geometry” panel.
Or would be similar to the FumeFX object that is.
"----Class Of----------------------"
FumeFX
"----SuperClass Of-----------------"
GeometryClass
3ds max will not let you convert it to editable anything and the fume grid does not render.
Any thoughts
I guess it would be nice if there was a SetRenderable to work with IsRenderable() on the object level
Return an empty mesh from GetRenderMesh.
Also return FALSE from CanConvertTo.
so what should I feed GetRenderMesh() not to make it render and what do I need in the third spot something about a View?
BOOL Delete = FALSE;
ip = GetCOREInterface();
TimeValue t = GetCOREInterface()->GetTime();
INode* node = theRender.ip->GetINodeByName(_T("Object001"));
ObjectState os = node->EvalWorldState(t,TRUE);
GeomObject *obj = (GeomObject*)os.obj;
Mesh *mesh = obj->GetRenderMesh(t, node, ?, Delete);
I have not looked at the Don’t Convert yet
Oh, I assumed you control the object source code, I didn’t realize you’re trying to do this for existing objects.
I might be going about this in a dumb way.
I have a Geometry plugin that makes a LOGO on creation. Say like multiscatter plugin would do. I want there to be no way the user can convert the logo into an editpoly or any item. I also don’t want the logo to render.
So I guess I’m not really doing this the correct way…
here is where I make it
int Render_ObjectCreateCallBack::proc(ViewExp *vpt,int msg, int point, int /*flags*/, IPoint2 m, Matrix3& mat ){
if ( ! vpt || ! vpt->IsAlive() ){
DbgAssert(!_T("Invalid viewport!"));
return FALSE;
}
if (msg == MOUSE_POINT || msg == MOUSE_MOVE) {
switch(point) {
case 0: // only happens with MOUSE_POINT msg
ob->suspendSnap = TRUE;
sp0 = m;
p0 = vpt->SnapPoint(m,m,NULL,SNAP_IN_PLANE);
mat.SetTrans(p0);
theRender.EditObject(); <- here is where I edit my new Logo
ExecuteMAXScriptScript(_T("max modify mode"), 0, 0); <- didn't find the c++ yet
break;
}
}
return FALSE;
}
Not sure if i will get away with this but…
I have changed this
virtual SClass_ID SuperClassID() { return GEOMOBJECT_CLASS_ID; }
to
virtual SClass_ID SuperClassID() { return HELPER_CLASS_ID; }
Max now thinks its a Dummy Object and does not render it.
Oh, so you are in control of the code. In that case you should do what I suggested earlier.
I’m not sure what the problem is, just override CanConvertTo and always return FALSE.
hahaha, I didn’t understand how the Object Plugin class worked. I started with a basic class that didn’t have them when I started.
Object* MYCLASS::ConvertToType(TimeValue t, Class_ID obtype){
//return SimpleObject::ConvertToType(t,obtype);
return FALSE;
}
int MYCLASS::CanConvertToType(Class_ID obtype){
return FALSE;
}
Mesh* MYCLASS::GetRenderMesh(TimeValue t, INode *inode, View& view, BOOL& needDelete) {
Mesh *nmesh = new Mesh;
return nmesh;
}
What you told me was right on the money.
Thanks for your help
