This seems to behave much better when you set “Reference Matching” to 0. I think maybe there's some weird interaction with the non-1 spatial scale there. I'll look into that.

Yeah it should be pretty easy for us to implement such a thing.

I think you could even hack it yourself by setting a different clumpid primitive attribute value on each object's guides. Then you can control the inter-object blending using the Clump Crossover parameter on the hair generate object.

I'm still planning to implement something that actually pushes apart the guides when you use the Part Guides SOP. Just haven't gotten to it. It's pretty straight forward to do it now though with the Guide Bend SOP and it's ability to take a direction attribute, just not a one-click solution yet.

I'm guessing the fact it took longer without args is just a coincidence? Did you run multiple times?

Did you run that first, maybe? Could be disk caching.

Just to throw in some more numbers - HairSOP2.hiplc took 16.75 seconds on my i7 5960x. It seems like we're having some trouble on threadripper - or maybe on windows. I'll see if I can find out more.
