  1. Hey there! I recently gave a talk to the Vancouver Houdini User Group about how Houdini can be used for making visual effects for games. It was a reasonably short lecture (~45 minutes) so I decided to record it afterward and comment the Houdini file a little so I could share it online. The lecture is targeted at film people who would like to transition into games but aren't sure how to get started. It's not a step-by-step on creating fluids or any nonsense like that, but rather a look at some of the ways you might optimize an effect for real time. If you're not familiar with who I am, I've written a little about how I got into games over on my blog: http://www.allegrodigital.com/?p=1991 Or you can go straight to the lecture which is free, and hosted on Udemy: https://www.udemy.com/game-effects-using-houdini-ue4 Hope it's of use to someone!
  2. Houdini 15 Point SOP

    You could request that you be added to RFE ID# 66570 if you'd like to help nudge them into improving the 3f vs v which was originally added by Rob East
  3. Houdini 15 Point SOP

    but v@myvec doesn't create a vector, it creates a 3f, so you need to use http://www.sidefx.com/docs/houdini15.0/vex/functions/setattribtypeinfoas well. It's not a matter of practice at this point, it's you creating more work for yourself because you want to. Which is ok, but I personally try not to exert more effort on a task than I save by doing it "the right way".
  4. Houdini 15 Point SOP

    Right but... When I test it on 100 points (which is much more likely if I'm bothering to create this particular attribute: - the point sop takes 0.16ms - the wrangle takes 0.17ms - it takes more time to type the expression than to click the option from a drop down (maybe you type much faster - Assuming I don't want to overwrite N, but create a new vector attribute I then need to either : -- write additional script to convert my edge_dir to a true v rather than a 3v -- or use an attribute create beforehand to set it up as a true v -- I also have to write a condition in there so that point 0 gets an attribute.
  5. Houdini 15 Point SOP

    Not exactly the same. Put down a point sop, and turn on "Add Edge Force" under the Force tab and take a look at the edge_dir attribute that gets created. It creates an attribute that points to the next point in the curve as opposed to a tangent. On a curve with 1,000,000 points it also takes 74ms on my computer, whereas the polyframe takes 140ms. So it doesn't break the bank in those very rare situations I've needed it.
  6. Houdini 15 Point SOP

    Yeah, the only reason I come back to the point sop now is for the simplicity of generating an edge direction attribute on curves
  7. Houdini 15 Point SOP

    My suggestion is to get away from the point sop as soon as you can. If you can learn how to do the same things either with vops, or wrangle nodes, you'll be better off. The point node is quite slow due to the time period it was programmed into Houdini, and while it can be easier to do some things with it (matching by id attribute, setting up an edge direction attribute), for most behaviour it's not much trickier and much more efficient at runtime to have it set-up in vops. I still haven't figured out what they're attempting to do with @ in the point sop, so I've pretty much just abandoned it all together (which might have been what they were going for).
  8. Houdini 15 Point SOP

    Teaching is horrible in this version of Houdini.
  9. Houdini 15 Wishlist

    Incredibly small protest.... but after decades of tutorials where people say: "Put down a geometry node, go inside, delete the file node" Maybe it's time that we just don't put file nodes down by default in geometry? If I want to immediately grab a file from disk, I always just press ` anyways since it's faster than tabbing down a geometry node and navigating to the file sop....
  10. Bring RBD objects to complete stand still

    I take that back. It works if you don't use packed objects. Packed fractured object does not work with rbd auto freeze. Non-packed fractured object does work with rbd auto freeze.
  11. Bring RBD objects to complete stand still

    Wait... so RBD Auto Freeze works for you guys with Bullet? I can very easily get it to work with RBD objects, but I *cannot* absolutely *cannot* get it to work with Bullet in either the latest daily or latest production builds...
  12. Which FX Houses have Houdini FX TDs?

    I'm happy to see Houdini growing in Montreal. I feel very hesitant to apply for work over there knowing how many people have been burned between Lumiere/Meteor/Fake Studio
  13. Which FX Houses have Houdini FX TDs?

    There's user groups in London, Toronto, LA, and Wellington! Don't be the odd man out, Oslo.
  14. Which FX Houses have Houdini FX TDs?

    every place is different, you'll just have to lookat job postings to determine what a place will be like
