  1. I have found that over the years I have developed a much better grasp on when to spend time creating the "ideal" set up vs brute force "getting it done". I guess you learn to pick your battles!
  2. This is what I'm really looking forward to, efficient lighting of scenes involving hundreds of lights and assets. It's really become commonplace now, and with now pretty much all render engines having transitioned to path tracing it's now much harder to use some of the old tricks for "faking it".
  3. Hey all, Saw there was no topic for this so figured I'd just make one to see what everyone's thoughts/opinions are on it now it's been officially announced. Personally quite excited to see it out and start using it, Karma looks very interesting. Quite a lot of USD concepts to ingest, seem slike there' s a slightly different name for everything Carlo
  4. You can do some of this one with the inspect mode: http://www.sidefx.com/docs/houdini/basics/inspection.html
  5. Vellum does looks brilliant, eagerly waiting the other roadmapped features though!
  6. It's very much a temporary fix as on my machine the old libfontconfig has some other dependencies that are broken with new libraries. Essentially I'm able to use Houdini but unable to render using mantra, I'm hoping there'll be a fix soon I'm going to have to install hou on windows to get stuff rendered out in the meantime.
  7. I contacted support and they've logged it as a bug so this should be a temporary fix until it's resolved.
  8. Replying to this for completeness, I got it running again by downgrading to the previous libfontconfig, making a copy of that and putting it in a folder before upgrading back to latest so my system is not partially upgraded. I then made a symlink and used LD_PRELOAD to force houdini to load that particular library. Doing this, I was able to get houdini to boot again with some fontconfig errors but it's running and working. Hopefully I can track down the actual culprit on my system but it's a temp fix in the meantime.
  9. Just seeing if anyone might know what this issue might be, I update my system pretty much every time I boot it up but have only run Houdini today to find it won't start. I'm running antergos and it's up to date. The error is: /opt/hfs16.5/bin/houdini-bin: symbol lookup error: /usr/lib/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var I tried rolling back my fontconfig version as I noticed in my pacman.log it had been updated a few days ago but this stops my desktop from starting on boot. I've read about having various versions of fontconfig installed that can conflict but I've only got the version from the official repo.
  10. I'd probably use a ramp/gradient for the colour if it had to be one light
  11. Lovely R&D, thanks so much for the share!
  12. Here is a way using the bullet solver to handle collisions copy_to_point_without_intersection_1.hiplc
  13. If you watch a tutorial, apply it to a personal project of your own don't just recreate it and be done. You've watched a destruction tutorial on a building, now apply that to your own project with something different like a bridge etc. and use what you've learnt previously to push it further.
  14. Installed it using the package manager, I'd only manually install it if you really needed to as I've had headaches in the past too doing it that way
  15. Yep, just checked and I am running 381.22 successfully with a bumblebee setup on arch and H16.
  16. If you browse to the folder you mounted the external drive under, you should be able to access it normally just like any other folder
  17. Thanks for the reply bunker, I tried this with a default shelf tool fireball and then the shelf tool upres to test. This works great and is what I've previously been doing, but when I make the changes above I can't seem to get it to work properly. Probably just a silly mistake on my part, I've attached a hip file with it all set up if you or anyone else has a moment to spare upres_test.hiplc
  18. Hate to necro this thread but I'm just doing some upres tests and this is the only mention I can find of this, is there any chance you could elaborate a bit on the steps needed to tweak the upres solver. Just looking for another way to control my upres sim to match the low res closely
  19. I haven't even looked at getting the disconnecting working yet so nice one in pointing me towards that direction. Will keep testing I guess if I come up with anything that works I'll update it here
  20. Any chance you got this working in the end, just doing some r&d at the moment having some similar issues myself!
  21. So concise, I have lots to learn still EDIT: thanks so much for posting up the hip file, saw where I went wrong with mine and got it working in the end!
  22. Tried my hand at this one, couldn't get the last bit with the bob exactly as it is though. https://beesandbombs.tumblr.com/post/124275875509/descending dot_circle_spin_v02.hipnc
  23. Had this web page bookmarked a while ago, has some of the basic math that you're after so hopefully gets you going in the right direction! http://www.designimage.co.uk/basic-colour-correction-maths-for-compositors/
  24. You can pad out the frame numbers with zeros using a number after $F so $F4 would give you 0001. I think this is what you're missing from your filename. You can check the docs for more info http://www.sidefx.com/docs/houdini/render/expressions
