  1. Best GPU for Render man and vray /stand alone

    I should've checked the date. My bad. Thanks!
  2. Best GPU for Render man and vray /stand alone

    What? There are tons of options out there. This is a moot point with the dynamic frequency scaling (Intel calls it Turbo). I regularly see above 3.0GHz on 2.2GHz chips when in "Turbo" mode for single threaded tasks. Mantra is one of the best renderers out there and there are many great CPU options that are reasonably priced. I think you're writing it off too easily and not really doing the research. If you must use a different renderer I'd do more research on them and really look at all the costs involved. GPU renderers look nice until you add up the cost of multiple high end GPU along with software license costs. These days a single GTX 1080 Ti is going for $1,200 because of crypto currency mining craze. Add up a few of those and now you can get some pretty freaking sweet processors for that kind of money.
  3. RAM cleanup

    Just ignore it. The cache manages itself and when it's out of memory it'll free some up. The cache helps performance so utilizing all of the memory for cache is a smart thing to do. Always having memory free and doing nothing is a waste of memory. It might also be the operating system level cache rather than the Houdini level cache. Same deal there, just let it do it's thing.
  4. Quad Sphere ?

    That's definitely more elegant and faster than what I posted. I like it.
  5. Quad Sphere ?

    A subdivided box will get pretty close but not perfect. From there there are a lot of ways to make it perfectly spherical if it needs to be perfect (example attached). quad_sphere.hipnc
  6. Mantra - Glitch / Flicker Error

    If you're using the Principled Shader it's on the displacement tab. If you're building your own shader it can be added there or changed at the object level per object with a parameter.
  7. Mantra - Glitch / Flicker Error

    It might be the displacement bounds are not big enough so neighboring buckets end up missing geometry that should be displaced into them. It's hard to tell from the compressed movie though.
  8. Slow network hip save

    That buffered save variable is nice. I didn't know about that. Besides that it sounds like the network storage is using synchronous writes. There's no reason to use synchronous writes for multimedia and content creation. It only makes sense where a silent failed write would have drastic consequences (like things dealing with money or sales). If the file server can be setup so it does asynchronous writes it should improve performance. The outcome is the same either way just one way tells Houdini to buffer and the other tells the file server to buffer.
  9. That's the issue. There aren't any laptops that will provide desktop like performance. Not even close. The ThinkPad P51 would be my first choice but it's still really slow compared to a desktop of equivalent value (note the P51 replaced the P50 model).
  10. I wouldn't buy a laptop if the primary use is going to be Houdini. They simply don't have the hardware to make it worthwhile. Not enough memory, not enough cores, lower end GPU. Get a workstation or at least a desktop form factor machine where it can have more cores and more memory (and more power and cooling for all of it).
  11. Enviro variables

    Houdini uses environment variables in a Unix like way and if the environment variable is set before launching Houdini then it'll use it. See the documentation on it if you haven't already. http://www.sidefx.com/docs/houdini/basics/config_env.html The short answer is yes, if you define PATHA variable as "/1" then any time you use $PATHA it'll get replaced with "/1" in the text. Beware using variables that look like $PATH because that's a critical system wide environment variable. Ideally it would be something not close at all to existing variable names to avoid any confusion. https://en.wikipedia.org/wiki/PATH_(variable)
  12. You're completely missing the point. It's a licensing restriction. SESI doesn't want people using the Apprentice version or Indie version to do major commercial work. That's what the more expensive commercial versions are for. If it was easy to convert the file types then it would be easy to break the license agreements. It's supposed to be a pain in the ass and controlled by only a few so the licensing agreements can actually be enforced. It's the same situation with the Orbolt assets too. If you buy the Indie version of the Orbolt asset it won't work in the commercial versions of Houdini. I think SESI will do a one time conversion of files (but probably not Orbolt assets) if a commercial version of Houdini was recently purchased. Other than that one time situation the different scene formats don't intermingle or convert.
  13. Houdini Multiple Session in Mac OSX

    There's an application for a Houdini terminal. It's a normal terminal but setup for the Houdini environment. Running the commands in a normal terminal won't work. Be sure to use the terminal in the Houdini folder. I don't have access to a Mac to give more specific info that that.
  14. How much memory do you use?

    There's nothing wrong with starting at 64GB of memory as long as you buy modules dense enough to allow room for future expansion. For a visual effects workstation I would go with 128GB of memory. For a general purpose workstation 64GB of memory is sufficient in my opinion.
  15. Hardware setup workstation

    The Ryzen Threadripper 1950X is by far the best value in that range. To get discernibly more performance than that price jump is significant.
