hi,

i am facing performance issues. while my object plugin is parametric there is a HUGE editor slowdown. i know why (because the object is rebuilt everytime something changes within the editor, nomatter if it belongs to my plugin object or not)

within the BaseObject *MyPluginObject::GetVirtualObjects(PluginObject *op, HierarchyHelp *hh)
{ ... Part i have placed all the generating code (which can easiely get quite complex due to high counts and much calculations)

So i wonder how i can prevent this and just have the object to be rebuilt when some parameters or childobjects have changed..

thanks for any help,
ello

Really, you should use the search-function of this forum. Just the keyword 'cache' helped me to find an entry within a few seconds. Hope it helps

edit: now i get memory leaks, they are related to this:

`

Free the objects you allocated before returning the cache

yes, but if i have one of my plugin objects as a child and i change its parameters, the change is only visible when i change a parameter of the other pluginobject (where the object is linked via IN_EXCLUDE).

Didn't you use the dependency list?

`

the first lines are there to make the animation possible. i guess there is a more elegant way, too..

if i put those AddDependence Lines into the if(!dirty) condition the objects only get invisible when changing parameters
