Using the mirror pose node. I tried using 2 nodes of it. One with a long blend time and another with 0 blend time. The blend transition gets some bad euler wrap corrections so i wanted to use the 0 blend version to snap the problematic ones to the target pose.
After some tinkering I realized that it was using the same blend time on all the nodes regardless of what it was set to. Suggesting the mirror pose node is a single instance and not unique
The issue is you cant use 2 mirror pose nodes and have different blend times on them. They will both use one of the blend times.
You can see this by taking one mirror node with a long blend time and another with 0 blend time, Layer the two on top of each other. say upper body and lower body. You ll see they blend at the same rate.
I ll see if i can get some videos together to make it clearer
