Help me with this Wire Constraints Example file from the tokeru site!

[Ronald Ruiz]

Hi! Ok here is the thing, I understand almost everything about the file BUT there is a thing that is driving me crazy and is happening in the "SOP Solver" inside the DOP Network, there is a merging sop using the constraints from the previous frame and adding new ones that are created by the distance between the points of the wires, the weird thing is that there is no accumulation of constraints happening, what I expected from this merging is that the constraints number will increase over time but for some reason they are deleted and recalculated in the next frame. So I tried a few thing with the file and found that if I "by pass" the wrangle node that animates the "pin" constraints things go as I expected (constraints accumulate over time and the for that reason the sim slowdown) WHY!! Even if didn't bypass the node and only change the range in the fit operation calculated in the wrangle from (... 1,0) to (... 0,0) making it "0" all the time killing the animation the sim work as before and deletes the constraints (no accumulation) but if I delete the whole fit operation and replace it with a value of "0" directly the expected accumulation goes on (you can check this if you run the sim being inside the SOP Solver). So maybe someone can help me to understand why this is happening, I think the Accumulation of Constraints prims is the correct behavior (at least is what I expected) but the sim runs smoothly if the constraints dissapear so... WHY

 

Here is the example File (I modified it a little bit: Geo name and a red sticky next to the node you want to bypass) HOUDINI NC 16.5
