  1. Procedural Potion Bottle Tool

    It's because the ramp is a float. You are saying that vector = float. If you skip the ramp and do vector hillProb = rand(seed+2); you will get a random vector.
  2. You mean you are flipbooking while simming? You could try the "Leave Playbar at Last Frame" on the flipbook options.
  3. Accessing ptnum on a wrangle

    There is a preset on the point wrangle to grab second input attribute by id:
  4. GTX 1080 may be crashing sims?

    It's actually an eighth of that, around 200 million voxels. Keep in mind the resolution of the volumes is particle separation * gridscale.
  5. Force render even if missing objects

    Set the "Missing Frame" option to No Geometry on the file cache.
  6. How find "Cracked Edge" ?

    I gave it a try, might not work on more complex geo but it works on your box . I find the unconnected points based on normals, and then put those points into the original primitives and rebuild them. I did something similar a while ago where I had lots of curves making up a tree. The branches wasn't attached to the branch before it, so I needed to find a way to connect the base point of a curve into the middle of another curve where there wasn't a point to attach to. That was curves and this is not, but it seems to work well for this too, albeit I turn the polygons to curves and then back to polygons. dv_CrackedEdge.hipnc
  7. Optmizing popwrangle

    Instead of setpointgroup you can: i@group_groupname = 1;
  8. Move in Z from camera: vector campos = point(1, "P", 0); vector dir = normalize(@P-campos); @P += dir*ch("amp");
  9. Fit vex is weird

    rand(stamp("../copy1","id",0)+0,47) You made mistake here. It should be 0.47 with a dot, not comma.
  10. Invalid Bindary Token

    What kind of primitives does the alembic contain? I've had problems with crashing alembics before if the animators include the animation controls by mistake. If you can, try and load different parts (under the Selection tab on the Alembic SOP) and try and find what makes it crash.
  11. Cook frame per thread

    Depending on what you are doing and how your geo looks like, you can also abuse compiled foreach loops to multithread otherwise single-threaded stuff.
  12. Ah nice catch! I haven't used the new sourcing system that much and didn't know about this. In the old Source Volume DOP you could use only "vel" fine even if it was consisting of .xyz scalar volumes. With the new Volume Source DOP however, it is as you describe.
