Houdini Indie and Apprentice » Black Refractions (eye geometry)

Hello,
I'm using Mantra for the first time and I'm having a bit of an issue getting my character's eyes to render correctly. My eyeballs are set up with the usual two pieces of geometry and the outer transparent surface turns the eyeball black. I'm using a principled shader core for the eye exterior with refractions and fake caustics turned on. I also tried using a classic shader core. The interior eye is using a principled shader with a metallic iris and subsurface turned on. I tried turning off the shadows using this tutorial: https://www.youtube.com/watch?v=xd7YMpTMZP8 [www.youtube.com]
Using the method in the video, I was able to get the iris to render correctly, but the eye whites are still black. I feel like there's a setting I'm missing like ray depth that's causing this. Any help would be appreciated, thanks!

Houdini Indie and Apprentice » Getting Renderman for Houdini to render displacement

Nice find Wojciech. I am unfortunately having the same problem. I can use the method described to apply displacement to, say, a sphere but it doesn't work with objects that I bring in. In fact, changing the radius on my object doesn't update the IPR like changing the radius on the sphere object does.

Houdini Indie and Apprentice » External guide curves for hair? Selecting individual guides?

Thanks for the help! I thought the guides weren't being selected because they weren't highlighted, so I thought it wasn't doing anything. Apparently there is no visual feedback as to which guides are currently selected when high quality lighting mode is turned on. Switched to regular lighting and now everything works as I hoped it would, which is great. Time to groom.

Hi, I'm back with more noob questions. I've been playing around with the guide curves I brought in from Blender and I'm trying to modify them further in Houdini. The hairstyle I'm trying to achieve has a lot of layered clumps so I have to be careful with how I place and adjust my guides and can't just take a screen brush to the whole thing. Is there no way to use the brushes on just the selected guides? I've been using visibility and edit nodes to modify isolated guides, but it's a bit tedious.
Oh, and another thing. Around how many guides is ideal for Houdini's hair system? I'm more used to XGen which uses a small amount of guides and I'm not sure if I have too many at the moment. Does Houdini have an equivalent to XGen's region maps or is parting handled by just having more guides?
Thanks!

Hello. I'm really new to Houdini and I picked up apprentice to see if I can use it to replace Maya and Xgen for making hair for my projects.So far it looks pretty good. The detail that can be achieved with the hair system looks really nice, but I can't seem to get as much control over the guides as I want. I've been looking through the docs and tutorials to see if there is a way to individually manipulate the guides, either through selection or a masking brush similar to Xgen IGS, but I can't seem to find anything.
I've also been looking into using curves generated from an external program as guides in the hair system. I saw this tutorial [vimeo.com] which does just that, but it looks like it uses an older fur system. Is there any way to add external guides into the newer hair system? Thanks!
