  1. Unexpected result with Portal Lights

    I'm on 17.5.391. I forgot to mention that... when there's no environment map, the portal light seems to work as expected, as you've seen. I think it could be a bug... Have you tried using another HDRI as a map for the light?
  2. AFAIK, you can also use directly the Classic Shader, which has some functionality the Principled shader has not included, including, if I remember correctly, changing the reflection model
  3. I have to say now I'm completely confused about the workings of portal lights. I've been testing some interiors renderings with Mantra, and constantly getting strange results. It seems the portal lights were the problem. I have setup and uploaded a simple scene to show how I'm configuring them and to try to understand why I'm getting the opposite results to what's expected: more noise /worse sampling with the portal lights on for exactly the same rendering settings. Worse quality picture is with Portals on. I attach the scene file, hope you can help me, I'm sure this is a very trivial issue but I'm not seeing what's wrong and this issues is causing me extremely long render times in my working scene. Thanks in advance! portalTest.hiplc
  4. Refraction has been traditionally one critized aspect of Mantra. Could I take a look at the shader?
  5. As a newcomer to Houdini, I can only send big thanks to Jeff about all the helpful stuff he has put out over the years, specifically the most recent webinars!
  6. Houdini 18 Wishlist

    I agree the appearance of "modern" can be deceiving and hide a less optimal UI. but I currently use Houdini with a (kind of) flat theme and I'm pretty sure I can find anything in the UI in less time than with the default heavily bevelled and convex-like shelf tools, and find it more more legible (I'm less distracted to elements other than text or icons) and of course pleasant to the eye. But that's a subjective opinion with no measurable data to support it. just my increased feeling of comfort.

    I know, this won't be a priority and doesn't need to be, but a flat modernized UI would be a welcome little surprise...
  8. CentOS for Linux newcomer?

    Well, I've tried CentOS again with a basic nvidia 1060 GTX card... and just works! Installed drivers via the nvidia CUDA repository using the method exposed in the comments section of this thread (like 1/3 from the start): https://access.redhat.com/discussions/3672301 Everything working fine after a reboot, first tests showing a +35% performance improvement in OpenCL over Windows 10, just awesome. Next days I will install Houdini, Renderman, development tools, etc. but first impression is being really positive even with this no-for-newbies distro.
  9. CentOS for Linux newcomer?

    Well, and update on my question: I tried installing CentOS, I liked at first look, not a single hardware issue. But then I tried installing the AMD Radeon Pro Drivers (installation successful it said) and then CentOs never booted again. Funny enough, booting with the "restore" kernel gave me a perfectly working amd driver, including OpenCL (I event tested it in Houdini and all well), but I don't consider this workaround a viable situation and obviously something is really broken and didn't have the free time to try saving my CentOS installation. So yesterday tried installing Ubuntu: same issue with the AMD Radeon Pro Drivers... once installed, Ubuntu never boot again. SO: I'm officially out of the Linux camp as long as I have a shitty AMD GPU
  10. Awesome: https://www.arnoldrenderer.com/news/press-release-arnold-5-3-gpu/ Seeing news like this, and the upcoming Renderman XPU, I'm more and more interested each passing day in knowing if Mantra will be GPU-based (or accelerated at least) some day...
  11. CentOS for Linux newcomer?

    Hi everyone, I've been thinking about migrating Houdini from Win10 to Linux for a long time (because in some sense I think is more of its natural environment and of course because of performance reasons) and I think I'll finally do it next days. I'm also learning Resolve / Fusion and Renderman, so the safe bet seems to be CentOS 7, as it's directly supported by these three sets of applications. BUT i have read terror stories about CentOS regarding nvidia/amd drivers installation hell, old software, not so user-friendly as Mint, bad desktop experiencie because it is server oriented, etc. I have to say I had Linux on my main machine for a couple of years a decade ago I finally removed it because I really didn't enjoy losing time fixing things after each update (I'm not implying is always like that or anymore, lots of years have passed since then). Also, I think is worth saying this machine is meant to be used only for 3D. What do you think? Any of you working with Houdini on CentOS? Thanks!
  12. H17.5 Launch Event March 7

    People who don’t know anything about it can’t tell you what’s LOPS about and I’m afraid those who can won’t because of NDAs and stuff haha
  13. H17.5 Launch Event March 7

    The only official mention that I know is this: https://forums.odforce.net/topic/40084-houdini-17-sneak-peak/?do=findComment&comment=193679
  14. H17.5 Launch Event March 7

    Currently CPU based, but will leverage GPU+CPU on the near (?) future. They call it Renderman XPU
  15. H17.5 Launch Event March 7

    Depending on what you already know... It will be, for the first time, a real plugin, will have a very responsive IPR and all the bell and whistles it has on other platforms (except for the integrated viewport in Maya AFAIK) which will ease its use inside Houdini. I read on support forums 22.4 could be released next week including support for Maya 2019 and maybe the first closed beta (commercial users ony?) of the plugin for Houdini. But what I'm really looking forward to is knowing more about all the Solaris project stuff teased on the 17 launch event...
