Just wanted to share my personal experience with LAMH and maybe suggest an alternative hair solution:
I bought the plugin last year and as of DS4.6, at its current build(LAMH 1.5), I still find it cumbersome and unstable - at least on my system. Crashes are frequent, I feel like I have to tiptoe around the plugin when working with it due to the underlying fear that it can crash at any moment. Saving the hair doesn't always work, I've lost 40 or so minutes of styling work more than once, and I've had one occasion where my save became corrupted and could not be loaded.
Furthermore in 3Delight I haven't been able to find a good setting to make the hair look realistic when rendered as Renderman Curves. The hair always looked better when imported as OBJ, but still never looking the same as the one previewed in LAMH, hence you don't always know what you'll get. When I have lots of hair on my model going the OBJ road has always been risky, most often DS would just crash moments after importing, and I've also been having placement issues (rotation and translation errors) and inconsistencies with the number of fibers imported. My first attempt at rendering LAMH generated OBJ hair in OCDS 1.2 resulted in a crash, and I completely stopped playing with LAMH from that point on.
Since then, if I need a fiber based hair solution I've been turning to ZBrush's fibermesh imported into DS via the GoZ funcionality. In my experience it's worked really well, it provides a fast workflow, it's stable and handles well when parented to the model in DS - with LAMH manipulating the model can have unpredictable results.
Also ZBrush exports the converted OBJ hair much more accurately than LAMH, I used TonySculptor's Hair shader with the fibermesh and when rendered it always looked very close to the hair when rendered in BPR in ZBrush. What's more, it renders fast in OCDS 1.2 and TonySculptor's hair mat only requires slight tweaking for it to look realistic. For illustrations or stills, this is my preferred alternative for now. I haven't tested with the 2.12 build though, I was hoping that by now it can finally render Renderman curves which would open more workflow options... but apparently it ain't so yet.
This isn't a value judgment against LAMH, I've heard some people have better luck with the plugin, maybe I'm just one of the unfortunate few who don't. I hope this'll change in future builds because I do like the potentials of LAMH, intuitive interface and all.
There was a mention a while back about t_3 being in talks with Alessandro, the LAMH author. I wonder what became of it...
