  1. Hi - I'm struggling to find a tutorial that explains the workflow for exporting a large heightfield terrain as tiles. I'm unsure where I would use a tilesplit/splice node for example - before or after my erode node? If I have a large terrain with many voxels, the erode takes a lot of memory. Can I use a tile split node before the erode to make the computation less demanding per tile, and somehow iterate over the individual tiles, exporting each tile's maps along the way? If I try to compute the erode on a very large terrain all at once, my pc runs out of memory. I would really appreciate any tips, links or advice you might be able to offer on appropriate workflows for working with large terrains and exporting tiled maps. Thank you Bryan
  2. This gotta be a bug, right? After troubleshooting it, I just can't imagine what I can have missed that would mess it up. So it's probably something I missed. procedural.web.v02.issue.hip EDIT: Seems the dev's added a convert line SOP in H15 that splits a curve/edge into separate prim's - but I would still like to know why the carve SOP doesn't work in this case.
  3. How can you move a copy independently of the other copies without breaking the copy node ? How do you add thickness to an extruded curve ? I was hoping Depth Scale was the answer unfortunately, no What node splits an extruded curve, by split I mean edge split ? Finally for this little batch of questions, can you merge selected vertices after a copy node, instead of them, in my case overlapping ?
  4. So before I submit this as a bug I just wanted to see if anyone else on here might have experienced the same issue. Houdini Version: 14.0.444 Step 1: Read in an animated cache (from wherever, doesn't matter) Step 2: use a split node to break something apart Step 3: plug the output of the righthand side of the split into a timeshift Step 4: Does the timeshift do anything? I have recreated this several times already. Every time I read in a cache (I've tried with many different types of caches), split something and try and use a timeshift on the right hand stream of the split, it does not work. Maybe this is a version specific thing, I haven't tested the latest release of 15 with this, I'm just curious if anyone else has come across this. Thanks -N
  5. Ok, I have many objects separated into point groups by unique suffixes. I'd like to split the suffix integer value from the array of group names. Then assign that integer to a custom attribute. I'm terrible at VEX so any suggestions would be greatly appreciated.
  6. Hi everyone, I am trying to simulate a bacterial growth scene by using wire objects. In story short i am splitting a wire object every 15 or so frames and getting an exponential growth. But my problem is that, i want the new split wires to try to come to constant length (like a pressed spring). and i want them to push each other away. Please take a look at my file. Am i even in the right direction?. how can i make the lines grow back to a size? by giving them a rest position every frame? thanks in advance. bacteria.hipnc
  7. So when I started migrating to Houdini a couple of months back, I really didn't get into the really simple stuff in POPs because I just didn't think that would be a problem - now it turns out that what I thought would be really simple really isn't very simple at all. or perhaps it is and I'm just too stupid (or too locked into my TP/Pflow thinking) to see it... Lets say I have a couple of particles shooting out from one point and I want to have particles "spawn" of these particles at random frames, inherit the velocity but shift the direction a tad. Final step is just have all points create trails using a POP Replicate to spawn stationary particles - but that part I get fine. Oh, and solutions using VOPs, wrangle nodes etc. isn't an issue, any solution will do. So we're just talking about creating simple growth pattern, something that is ridiculously simple to do in TP or Pflow in Max. Like this setup I did in TP 1-2 years ago, the secondary growth patterns.
  8. Hi, guys. I get a problem maybe it was be asked before, but i can't find any tips. There is a grid polygon and i add a line on it by add SOP. Is it any way split the grid to two part by the line even the vertex number was not right. I can split it by polySplit or Clip, Break SOP, but they were not flexible enough. Any help will be appreciated! Thanks. grid_split.hip
