Today Look at My Hair is on sale for a great price, I've been on the fence about picking it up. However I use Iray and I know that the renderman curves don't really work with iray. But there are some workarounds, exporting as OBJ being one and some sort of tool (catalyzer? Forget the name) that did something too, not sure if that's just a fancy word for OBJ export too though. Question I have for owners of the tool, if I buy this for use in Iray and I going to end up with crippling render times due to large OBJ files?
The price is really good so I may get it anyway just for bears and stuff but I'd like to hear people's experiences with this product with Iray in mind. Thanks!

The obj files eat a lot of memory, but render times are okay. There are some tricks when converting the hair that will help. The reason why LAMH hair doesn't work in Iray is due to some function that Iray currently hasn't implemented.
The Catalyzer works very well, but only for AM's animals. The process of creation of the settings is, according to AM, pretty time intensive and complicated, so there's no chance that you'll see wide-spread solution settings for the Catalyzer any time soon.
Saving the hair as Fiberhair from LAMH instead of an object works too.
Iray and LAMH work fine together as long as youn don't get carried away with the amount on the fibermesh.
The fibermesh in the image is right at 320,000. I found out after I can go as high as 600,000 before the scene freezes
The problem is that you really want something in the millions of hairs to look right, which most people can’t manage.
When I was experimenting with dForce on transmapped hair i found that it got kind of sparse looking but adding a geoshelll kind of filled in the gaps pretty well. I wonder if anyone ever tried that.
