  1. Time-based paramater in /mat?

    Ok, I understand my bad! jeje ... Maybe creating the string as an attribute in sop and bind it in mat?
  2. Time-based paramater in /mat?

    Hi David, I'm not sure if it will works ... but have you already tried with "/my/disk/pointcloud.`$F`.bgeo" ?
  3. Birth particles on a shadow

    Buondí! If you're talking about self shadows I think you can make a dot product between normals and the difference from the points position and the light position. (if the light is a point light), something like this: @Cd = dot(@N,@P-point(1,"P",0))>0;
  4. 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!
  5. changing a parameter on everynode in my scene

    That's far easier and faster!!! Thanks!
  6. 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
  7. 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
  8. 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.
  9. 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).
  10. 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
  11. 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
  12. 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)
  13. 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
  14. 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?
  15. 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?
