  1. I think the cheaper way, if you have already all approved and you just want to "merge" the effects, is to "point deform" the geometry. Just put the geo to deform (the dented, simulated one) in the first input, the bending box at rest into the second input (probably a timeshift at the first simulated frame will works) and the bending box simulated into the third input. I hope this helps!
  2. changing a parameter on everynode in my scene

    That's far easier and faster!!! Thanks!
  3. changing a parameter on everynode in my scene

    Surely with a python script that can look something like this: for object in hou.node("/obj").children(): if object.type().name() == "the type you're searching for": for node in object.children(): if ... //some other condition, if any node.set... //and here you set the parameter you want the value you want
  4. Mantra Render to Disk Stops Randomly

    Good idea the RFE Another option is to manage that with thinkbox deadline, for one (and maybe two) pc is free. And you can also manage dependencies and so on ... it's really useful for me
  5. Mantra Render to Disk Stops Randomly

    Sometimes you can have a read error loading the cache, you can try selecting "no geometry" instead of "report error" at "missing frame". That way it will be rendering your frame without your geo, so you must pay attention later.
  6. Blur Volume Using Volume Vops

    You can also convert the volume to vdb and use de smooth vdb node, where you can plug a mask for the blur effect (the mask should also be a vdb volume).
  7. Texture on flip mesh using rest, rest2

    Too late, really ... but I had the same problem working with rest and rest2 from flips and using procedural textures ... the only way it worked correctly was renaming rest as rest1 and then, in an attribute wrangle, using this expression f@rest = lerp(@rest2,@rest1,@rest_ratio); which is actually from this post by Mario Marengo
  8. Upcoming Build- future AMD vs Intel

    Hi @lukeiamyourfather! Just check here, there's some interesting info: https://www.sidefx.com/forum/topic/48975/?page=1#post-222234 It seems the Ryzen has a good performance on OpenCL, like a GTX 1070, but there you have all the system memory. It sounds interesting
  9. Upcoming Build- future AMD vs Intel

    Shouldn't be the internal OpenCL from the CPU? I used the i7 OpenCL capabilities in some test and worked well But now that you say that I go to check if the last CPU have OpenCL capabilities (Y)
  10. i7 6800 or 6900k?

    A friend of mines just bought one but is waiting for the RAM right now ... I think I'll wait a week or so to see what happens
  11. Upcoming Build- future AMD vs Intel

    Not in Houdini, but there's some data (see Rendering: Luxmark CPU OpenCL): http://www.anandtech.com/show/11170/the-amd-zen-and-ryzen-7-review-a-deep-dive-on-1800x-1700x-and-1700/18 It's strange that 1700x and 1800x have the exact same performance in this case, isn't it?
  12. i7 6800 or 6900k?

    Why not a Ryzen? With that price difference (and same performance) you can buy a top GPU. The downside is that you have a limit of "only" 64GB of RAM and the CPU and system are fresh, so I can't talk about stability... Anyone has experience with them?
  13. Fluid Sim, Higher Resolution?

    It's really better if you cache out the sim using the "compressed_cache" node. It will use only the ram needed for the sim, and then only the ram needed for the surfacing. Maybe just with that it will works. 1 - "Save to disk in background" on "compressed_cache" it will start hbatch so you can close your current Houdini session 2 - Save to disk in background on "particles fluid surface" ... same as point 1 this way is more efficient.
  14. Fluid Sim, Higher Resolution?

    Can you upload the frame 137 cache? maybe the compressed_cache one 7zipped... so I can play with that directly
  15. Fluid Sim, Higher Resolution?

    Hi Atom, The distibuted sim works only if you have 2+ pc and halp exactly in this situation. So you have a rough total of ram that is the sum of your pcs ram. In this case you can't use distributed sim as you have just one pc. I think that depending on the flip sim it can be possible to split it. If the fluid is fast moving it will be very hard to set up, but for slow moving FLIPs I think it will be possible. Anyway I should try to be sure. Can you share the HIP to see if is there any optimization that can help? I'm thinking for example that the convert vdb node has and automatic partition in it, maybe you can set the partitions to higer values. Also the "VDB from particle fluid" has an option "Tile size" you can try setting the size to smaller values as that way should use less ram. I hope this can help. Cheers! Marco
