  1. Thanks @ejr32123, I appreciate the response - really surprised there isn't more clearer information out there about any of this stuff but I guess people just use matchmoving software for movies so nobody really needs to do it themselves. . I'm sorry to say I don't understand what you're suggesting - I looked up the sensor size and it is 1/2.3 (which is 0.43478) and actual dimensions 6.17mm x 4.55mm but again i don't see where those numbers would make sense anywhere in these settings, they aren't anywhere close to that default recommendation by Sidefx unless I shift the 0.43478 by two decimal places. The specified focal length on the camera is "20mm (with 35mm equivalent)" - is that where you're getting the 36 you recommended? Very very confusing!
  2. Hello, I am trying to understand how to match a real camera on a drone with a 3D camera inside Houdini. I am not a photographer so only know basics about cameras and I have found previous posts here and the SideFX documentation - https://www.sidefx.com/docs/houdini/ref/cameralenses.html - listing various formulas for calculations but those confused things even more: " You can obtain a good fit between the Houdini camera and a real world camera by matching a measured lens’s horizontal angle of view, and deriving a Houdini focal length value that reproduces it with the default aperture 41.4214." I have the real camera specifications: it has a 20 mm lens, a f/2.8 aperture and a dimension of 4056 x 3040 - how does that apply? Their "basic mathematics" formulas are pretty much over my head - I really wish they would include examples of things like this in the documentation I see a few blender and maya tutorials online for similar questions so I guess I'll see if those help but if anyone can offer clearer instructions than the "help" documentation did I would be really grateful! Thanks

    Thanks for the tip, @Librarian, I'll check it out!
  4. Subdivision levels

    Okay, good to know, thanks. I'm looking at both Houdini and Blender for modeling right now and Blender has a bunch of sculpting tutorials versus houdini so will probably just use that instead.

    Hi @RTHMan, this is a good question to hear while I'm learning Houdini, but unfortunately I don't have a facebook account to see what was written. Could you please paste the answer here? Thanks!
  6. model sliced vegetables procedurally

    Thank you for the link, @Atom. The sped up timelapse does help give me some kind of idea on how I can approach it in Houdini. Right now, I guess my biggest question is whether to try doing it in Houdini or just go back to Maya where it seems more straightforward. I'll have to experiment I guess, and maybe try the quad remesher he mentions in the video. Thanks for the tip, @bentraje, I was really just looking for modeling things already sliced, but the slicing tools do create some more possibilities. Interesting!
  7. Hi there, Does anyone have a way to model sliced vegetables procedurally in Houdini? Things like pieces of lettuce, sliced tomatoes and pickles - the sort of things you put on sandwiches, etc. Basically I'd like to make a Hamburger with all the fixings I'm coming from Maya where it's pretty much all done manually and I haven't found any food-related modeling posts in the forum here to get any tips from. Thanks for any pointers you can give me! -G
