Hi,
I am not absolutely sure that this problem is caused by the SDK but i have been running
into a strange behaviour regarding ViewportSelect.PickObject(). I have a toolset of python
ToolData tools which were single object selection only until now. I wanted to extended them
with the capability to run with multiple object selections. So i added the PickObject() method
to my tools BaseClass.
But when I run any of my tools now my ram is flooded extremely fast. The speed depends on
the scene size and the size of the multiple object selection. It looks like the ViewportSelect is
allocating some memory for the object list passed to PickObject() and doesn't free that memory.
I have tried multiple variations of my BaseClass, in which the ViewportSelect is actually a class
member to throttle unnecessary re initialization of the vpselect object. Here is a version stripped
down as much as possible where the vpselect is not a class member to avoid any problems
caused by that.
Am I doing something fundamentally wrong, or is this just a bug ? Thanks for reading,
Happy rendering,
Ferdinand
Hm,
it seems that I have solved the problem for now by not making the viewportselect object a
class member, but that should be mentioned in the docs, as the only thing that keeps
vpselect from freezing the computer is the python garbage collector.
happy rendering,
