  1. Hey guys. Is there a way to use heightfield erode on a geometry or VDB. Let's say if I have a box, and I would like to apply erosion, how would I do that? Cheers!
  2. Hey guys. I'm trying to make a similar rock formation like in this video. At 11:30, the guy explains how he displaced edges with computing tangent. Can someone show me how this is done? I kinda replicated the process up until this point. Here's my hip file. Cheers! rock3.hip
  3. Redshift Proxy Workflow in Houdini

    I have a question about materials. You need to setup those before you do a RS proxy render, right?
  4. Hey guys. I have small simulation of a building collapsing. Before rendering, I switch to high instance pieces and when I try to render current frame with mantra, it's pretty fast and it doesn't use that much RAM. But, when I try to do the same render with Redshift, my RAM usage goes to the max (16GB), and it takes forever to render one singe frame. Why is that? EDIT: found the answer here:
  5. Is there a Hoduini wizard, who could explain, how the process on the picture below is done. Cheers!
  6. I'm not an UV expert, but I made this quick hip file. Take a look, maybe it will help. VDB_rock_autoUVs.hip
  7. If you have a high poly mesh, you do your UVs on a low resolution/poly mesh. You can make a low res. mesh by converting your high res. mesh into VDB, and then convert it back into polygons. I also use GameDev Auto UV, but sadly it doesn't do a good job every time. Check out the videos, maybe it will help. https://www.sidefx.com/tutorials/houdini-game-dev-tools-auto-uvs/?collection=48
  8. At 23:30 in the video, he also talks about grouping points with cluster points node, so he can cut the geo for the UVs. He said, he found the edge for each cluster, by looping over? How did he do that?
  9. Camera question

    What about a different lens? Like changing the focal length. Will this work?
  10. Hey guys. How can I make objects appear bigger in camera? I mean, I don't want to scale up the objects, thus losing the details. Cheers!
  11. Group edges

    I've been searching now about this, and I couldn't find anything. I'm guessing there is a way with writing some code to detect in what direction the edge is facing, bud sadly I'm not there yet. EDIT: I think somehow you must do a for each loop, where it will to check each edge for it's direction.
  12. Group edges

    Hold down SHIFT + A and middle mouse click on each edge. Once you have all the edges selected, press TAB (while your mouse is still in the viewport) and add a Group. That's it.
  13. Hey guys. How could I delete all outside or random pieces without manually selecting them after a assemble node? Cheers!
  14. Thanks! I will try do apply this onto the cube, and the try to erode it the way anicg showed.
  15. Thank you. I was looking into heightfield project node, but what if you want to erode a more complex geo, like this cube?
  16. When I make a FLIP sim, and when I add a particlefluidsurface node, the colour changes into blue. Why?
  17. Hey guys. I have a small scene with 2 cameras. When I do a redshift IRP render in Houdini render view, and when I try to switch from cam1 to cam2, nothing happens. Shouldn't the render view auto update when switching the camera? I also linked ROP in IPR node, and still nothing. Cheers!
  18. Anyone? When I load my exr displacement into RStexture node, the geo just get bigger a little bit. EDIT: Looks like forgot to add UVtexture node at the end of the low-res geo. Silly me
  19. So I baked out a displacement map in .exr format and also tested it in Mplay, and it looked fine. When I set up everything like in the video, the displacement map does not show up. But when I plug in RSnoise into displacement, the geo gets displaced. Are there any specific settings that I need to change in the bake node when baking for redshift?
  20. Unified Noise - Static

    Ok, I think I got it with the ray and edge fracture. Can you please show me, how to do implement the attribute noise into this, and also how to do it with findShortestPath. Here's the hip file. Thank you! unifiednoise_static2.hip
  21. Hey guys. So, I'm doing a Unified Noise - Static in the VOP node. Now my question is, why are these weird lines and big grey areas coming up (see the picture)? Also, here's my hip file. Cheers! unifiednoise_static1.hip
  22. Unified Noise - Static

    I'm trying to get like "clean" lines, without any grey areas, like on the picture.
  23. Cleaning up the geo

    Yeah...there is a trade off.
