Hi people
Suddenly I noticed my scene was responding very slowly and its size increased from less than Imb to 70Mb.
I found out the culprit : in the Out network, the “mantra_ipr” had been duplicated more than 700 times.
In the edit menu, I noticed a lot of items called “auto create ipr rop”.
Deleting all these nodes took forever.
So what does create automatically IPR rop's? The render region?
Thanks
Gz

Happens to me too sometimes. not sure what causes it.
Someone suggested it may be the cat in an earlier thread lol

Could you point me to this cat? I want to have some words with him.

I narrowed down the problem, it's when I'm dealing with bones. The simple action to select a bone will make about 100 “Mantra IPR” nodes appear…
