  1. Underwater Caustics

    There is an option to periodically loop over a set duration of time. With that shelf tool, it's possible to create ocean surfaces without simulation. The ocean spectrum / ocean eval SOP node combo are sidefx's implementation of the HOT plugin https://code.google.com/archive/p/houdini-ocean-toolkit/.
  2. Underwater Caustics

    The ocean tools I've found work best to create a nice rippling surface http://www.sidefx.com/docs/houdini/shelf/smallocean It's possible to tune it to look like a small pool and not an ocean by doing things like taking out directionality of waves.
  3. Reveal old ForEach SOP?

    -> optype /obj/geo1/foreach1 Name: foreach1 Op Type: foreach Op Type Label: "For-Each Subnetwork" Net Type: SOP Script Directory: sop Net Type ID: 1 Table Name: Sop You can use the optype command to get more info. You can see here the operator label has been changed, but it is still the OG foreach node.
  4. Reveal old ForEach SOP?

    Doesn't it still show up as for each subnetwork? http://www.sidefx.com/docs/houdini/nodes/sop/foreach
  5. velocity fields for grains

    popadvectbyvolumes isn't working for you, or are you trying some other method?
  6. More than 1 DOP network

    You can use the brain icon in the bottom right to select which DOP network the shelf tools target. http://www.sidefx.com/docs/houdini/dyno/manage
  7. Vdb to vray quality

    The biggest issue with getting Vray to match Mantra, is that Vray doesn't scale the of voxels by their size. Every voxel is treated like a 1x1x1 (unit) cube. This means that anytime you change the resolution of a simulation or volume, the opacity (and intensity if fire/emissive) will change. The higher the resolution of the volume the more dense/opaque it will appear. This is a very frustrating aspect of using Vray to render volumes.
  8. Houdini 16 + 2017/16 MacBook Pro

    Yes, I tried the first production build of H16 but couldn't get OpenCL to work. I haven't tried newer builds of 16, but maybe it works better now.
  9. Houdini 16 + 2017/16 MacBook Pro

    osx 10.10.3 mid 2015 mbp AMD Radeon R9 M370X VRAM (Total): 2048 MB still using h15.5
  10. Houdini 16 + 2017/16 MacBook Pro

    It works ok, there is only one MBP model that has dedicated GPU though. You would have to get the most expensive 15" I think.
  11. Smoothing Voxels (at render)

    http://www.sidefx.com/docs/houdini/render/volumes#volume-filter
  12. Saving H16 geo with H15.5 Compatibility

    HOUDINI15_5_GEO_COMPATIBILITY This setting will enable the saving of .geo/.bgeo files compatible with 15.5 versions of Houdini. If this is not set, files with polygons or tetrahedra saved in Houdini 16.0 or later will not be loaded properly in Houdini 15.5 or earlier.
  13. Vector / 2D rendering ?

    use the wren output driver to render vector images
  14. 2D dynamics

    Yes, I've done this before. It's a good way to do it. You can set it up with a position dop, sop solver or geometry wrangle depending on the object your simulating.
  15. Python load geometry as packed disk prims?

    primitive = node.geometry().createPacked('PackedDisk') primitive.setIntrinsicValue('viewportlod', 'box') primitive.setIntrinsicValue('unexpandedfilename', 'default.bgeo')
