  1. Does anyone know whether or not a fisheye projection is possible to write for the viewport? I'm looking around on behalf of a friend, and I think it might be possible, from perusing the HDK, but can't tell for sure. If anyone knows whether this is possible or impossible, either way, it'd be great to know. Thanks!
  2. What version of OpenVDB are you linking against, the one that ships with Houdini 16, or from Github? And there have been some HDK/OpenVDB changes in the logs; I'd try using 16.0.557 or later if you can.
  3. You need to put it in backticks, and use a single-dot for the current node: `opname(".")`
  4. Yeah more ram/HD space the better, if your motherboard can support it. For your current setup, you can totally get used to using Houdini just fine; obviously keep in mind you won't be winning any benchmarks, but for just getting started for as inexpensive as possible, you're pretty close to having something decent to start with; I would replace your graphics card with a 6GB GTX 1060, for $250 USD (I use one on a 2560x1440 screen, works great). Also, I've found that older 12-16 core (24-36 thread) workstations can be found on eBay for pretty good prices, and are a cost effective way to acquire cpus for heavier sims/renders. Often times these machines can support anywhere from 96GB to 256GB of ram too. I also use Linux Mint. Good luck!
  5. if you need to save disk space, you might find it useful to convert large particle sets / point clouds into Points VDB and saving that VDB primitive to disk in your bgeo. Haven't tested rigorously but seems promising.

  7. The initial data for DOPs simulations requires .sim files. For FLIP (and maybe some other solvers), technically you could probably use a bgeo as the source, giving it some initial velocity and such based on that frame of a sim; but you're not actually resuming a sim, you're starting a new simulation, and it may not match up very well since it's an incomplete snapshot that doesn't have the whole state of the system like the .sim files would have. *edit* what vtrvtr said
  8. Yeah that's awesome they added it; I switch between left/right handed mice/stylus and backspace its great. There is also a Left Handed Menus option, to move the menus to the left side of the cursor instead of the right side, if you prefer that.
  9. Definitely sounds like a bug, though I haven't hit it; I'd submit it pronto.
  10. Try the Group Expression SOP with: @numvtx > 4 Group features were broken up to be easier to support/expand, and to make it easier to work with groups. Many of the features crammed into the Group SOP were difficult to find/use. Hope that helps!
  11. Yep, that's what I was curious about! Glad to know it's in there! Thanks @Sepu
  12. Thanks @Atomthat's great! Does RedShift allow variations when instancing lights?
  13. I too am curious, its good to see AMD surging in the right direction
  14. That's interesting how much Active Radius made a difference on your system! I wonder what was behind that? Single proc vs dual proc? Or maybe the operating system?
  15. Thanks so much for the conversion @galagast that's great! Here are the specs for the system I ran those tests on (totally forgot to include/mention that before, thanks!): Linux Mint 18.1 2x Xeon X5670 @2.9Ghz 96GB RAM GeForce 1060 GTX I also updated the original post to clarify they were disc lights, not sphere lights.
