Hi, how can I find out if an object is being affected by a deformer or not.

Check this out:

BaseObject* BaseObject::GetDeformCache();

I'd say if it's not NULL, there has been some deformation going on

Cheers,

While that is correct, GetDeformCache() may return NULL for other reasons (and the object in question still be affected by a deformer) such as cache not yet built.

A better approach might be to see if the object's children are deformers as an additional test:

Bool deformed = (obj->GetDeformCache() != NULL);  
if (!deformed)  
{  
  LONG info;  
  for (BaseObject* child = obj->GetDown(); child; child = child->GetNext())  
  {  
      info = child->GetInfo();  
      if (child->GetDeformMode() && ((info == OBJECT_MODIFIER) || (info == OBJECT_HIERARCHYMODIFIER)))  
      {  
          deformed = TRUE;  
          break;  
      }  
  }  
}

Thanks all. The only problem with checking for deformers as children is that a deformer can affect it's parent object and the hierarchy below that parent, which means I will have to traverse the whole hierarchy from the top level parent, which I was trying to avoid.
