  1. Creating water tight meshes from low-quality geometry

    Depending one the shape you can also do shrink wrap, or a bounding sphere and a ray sop for low poly. The logic required for hard surface poly reduction to be the equivalent of simplygon is pretty complex so you generally need a complex HDA for that. Some of the processes to run are : Small part reduction, shape preservation, optimized triangle use, fuseing below certain thresholds, best fit scenarios for different simplified shapes like plane, box etc, Attribute copying, etc. The poly reduction sop has come a long way in H18 so I would recommend starting there.
  2. Houdini 18 Wishlist

    This is Karma ^. Mantra will be retired once Karma becomes full featured. You can start to use it now within the Stage context in H18.
  3. Houdini 19 Wishlist

    This is 100% needed.
  4. SeaHUG Winter Showcase

    XBOX is hosting the Seattle Houdini User Group's : Winter Showcase. Join us at Microsoft's main campus in Redmond, WA at Studio B Today Dec 3rd, 2019 from 6pm-8pm Please RSVP for more details. [https://www.meetup.com/Seattle-Houdini-User-Group-SeaHUG/events/266499858/](http://meetup.com Seattle Houdini User Group) Join the SeaHUG group for better than last minute announcements
  5. FBXoutput

    Here is a file with three ways to do it in sops, tops, and in python. There are a lot more ways to do it too as Twan has mentioned to game the system too. There are RFE's to have this option too added at some point... FBX upgrades are not common. They actually just made the code open source for the FBX rop. fbx_sequence.hip
  6. VAT soft body import to Unreal loop drops a frame

    You need to adjust the shader to handle the texture lookup differently for Padded by Two. I have not looked at the unreal shader in a while, but unless there is a check box that changes how the lookup works internally then it won't work. You should submit a bug to SideFX to fix the issue.
  7. Houdini UI broken on new Dell XPS 2-in1

    What is the graphics card? It is possible it is a not supported one. The second thing I would suggest is what you have already done by deleting your preferences. Another alternative is to reinstall Houdini. If it's the graphics card issue there isn't much hope for you.
  8. FBXoutput

    This has been a long time design "feature" of the fbx exporter in houdini. To get around it you can use a foreach loop in sops, a python for loop, or tops with each task split separately.
  9. If the admins put it on your system you should talk to them as it would be unrelated.to Houdini. If you are trying to crack Houdini I would say you will get yourself into a lot of trouble.
  10. Move Houdini to another drive

    On install of Houdini just change the path of the install location. For personal preference set this variable before start. $HOUDINI_USER_PREF_DIR/ https://www.sidefx.com/docs/houdini/ref/env.html The integration is to complex to post move the main install by hand. However, you can easily copy your personal preference.
  11. Issue in RGBA Heightfield Export

    You said you were exporting heightmaps earlier. For those certainly use .exr, anything with 16 bit data scope. EXR are little large for general use everywhere, and most game engines always by default expect them to be data maps as the information is lossless pixel value for pixel value. I still can't believe unreal can't handle .tiff how many decades before they fix that... As far as TGA Houdini is not necessarily exporting it wrong, and Substance is not necessarily exporting it right. Their default exports and options are designed for two different use cases. Houdini default was not intended to create textures through tga. tga has not been used in other industries besides games in a very long time. You can export out of Houdini with out doing the premult and the other effects you are seeing, but you would need to share a simple scene file. There are many workflows to export and ways the data might change so it's hard to tell you specifically what setting too change with out giving a very vague list. PNG should have a separate alpha channel. I would have to see your example file to explain why your having that issue.
  12. Issue in RGBA Heightfield Export

    .tga by default is premultiplied by it's alpha and it has and sRGB look up to it. You best bet is to use a linear texture format such as .exr which is linear by nature and is loaded by most engines. I know Unity and Unreal do now load 16 bit of the data. Look at these documents for more info. https://www.sidefx.com/docs/houdini/render/linear.html TGA is a really outdated texture format and I would highly recommend to discontinue use of it in production.
  13. Houdini 19 Wishlist

    None of the above are smaller wishes. I wouldn't worry. These wishlist have been around for well over a decade for each major version. Plus as noted this is non-official, for actual BUGs, RFEs, and Question they need to be submitted to support in order to be considered. SideFX staff may be lurking on Odforce, but they do not actually monitor outside SideFX.com forums. Mostly these threads are for ranting, venting, and once in a while a collaborate group hive mind for features that should exist. Also a lot of re-directions for features that do exist, but are obscure in the Houdini lexicon of terminology like the past and thankfully dead Cookie Sop...
  14. Houdini 19 Wishlist

    Short answer... H18 will be coming out soonish. Around their typical Halloween time period. Long answer... SideFX typically releases at three different points in the year around Fall, Winter and Summer, closely tied to Halloween, a month before GDC, and at Siggraph. On average with a minor release a major.minor version release cycle last about 200+ days. A little more than 7 Months+, with a few exceptions that are notable due to the technology they release in those non-average years. So theoretically we could see a 18.# at Siggraph based on those trends, or if they have some cool stuff that was not ready to release around GDC. This is what happened to TOPs the last release cycle, almost but not quite ready for 17.0 but big enough to garner it's own minor version. The farther out it gets harder to predict because there is a +/- of a few months. Plus even though we are in a period of major and minor .5 releases they don't need to follow that in the long run. We due know from Siggraph that the next one would be H18. Also there has never been another minor release number besides .1 and .5. For a side project I had Houdini analyze Houdini for these trends. At a certain point prior to a release it makes no sense to continue adding wishes that we will not be able to be full filled. As I recall someone else started the last wishlist kind of early too?
