  1. I'm try to orient the pyramid object to follow the normals of the tube, each pyramid should face where the normal (of the primitive on the tube) is facing. Polyframe on the pyramid doesn't help. Now they are all facing the same way. The last image with the red arrows shows where the pyramids should be pointing. (there is a hip file at the end) orientation in copy to point.hiplc
  2. 2 flip objects in one sim

    Just trying to have the spherical water interact with the flip tank, but it doesn't seem to see it, it's ignoring it, have I set it up right?
  3. particle fluid tank VS Ocean Source (Type flat): Does it matter which one I use for a FLIP simulation? is it old vs new? is it standalone flip vs ocean merging? or it doesn't matter which one I use even for simulation time or other?
  4. In Houdini this is one primitive (the red line is just a drawing). I can remesh, but what's very important is to create an edge/line/split in the middle same way as in SpeedTree. I want to use it to fold the leaf. Any idea what sop would do it? is there a way to draw a line and magically an edge would be created? Or any other way.
  5. [HELP] Heightfeild to polygon terrain problems

    The simulation is it volumes (smoke), or also lava? in other words, RBD collision just for the crater or collision with scattered rocks and trees? If the sim is only for smoke going up, then your scattering should not even care about the eruption, it's as if you have a normal terrain, you scatter your stuff on the heightfield and cache it as geometry to add later. Since you have already a texture in Cops, you know you can bring in any mask or erosion result into cops with a sop import, and channel copy. About the texture it's unclear what the simulation does, does it blow up the top of the mountain? I don't see a crater on your mountain. Are you scattering rocks that will be thrown as part of the eruption? or do you plan to blow up the top part of the mountain? Maybe if you post the dynamics part, it will be clearer. or if you have a reference you're trying to replicate.
  6. This nodes seems too greedy and I cannot get anything out of it: It reaches the max RAM (32GB) very very quickly with very low res mesh, while with the same terrain a Convert Heightfield node gives me dense mesh. The maximum I can get out of it is what you see in the screenprint, (33000 polygons) completely useless, if I go higher than 0,03 in base density, it asks for more than 32GB RAM. While the detail is there and I get it with Convert Heightfield (16.7 million polygons) with no RAM issues. How do I get it to work: less density in the flat areas and more density in the detail areas?
  7. Where can I find this feature in H18? cluster pieces in Voronoi fracture.
  8. Thank you. It's not working. That one is dealing with interior detail. I need the functionality of the old "Delete Exterior Cluster Edges". I've tried the new node but it's not working:
  9. It's not the first time, but when the firewall catches mplay sneaking out to internet, it asks me whether I let it out or not. mplay being mplay, in mind should not need internet, a player. But it then refuses to work.I go to the firewall, let it out. and it works. Any idea if SideFx is doing "something" with mplay? I mean there is a separate choice in the launch screen to send anonymous data or not. Or does it need some update? (it's a daily build, fresh?!).
  10. I'm having trouble with an animated alembic, that remains static. To test I have limited the selection to "Only deforming or Transforming Primitives", and it's still there, so the animation is there but I can get it to move.
  11. Substance Plugin in Houdini doesn't work with Painter, works only with designer. Right? It accepts only sbsar files (designer files) both the "Lab Substance Material (Beta)" in Sops, and "Labs Substance Archive (Beta)"in Cops. Has anyone somehow Substance Plugin with Substance Painter? I seriously don't get it. they've done quite a lot of work, months of waiting, and they've pluged it with Designer. But designer outputs sbsar files for Painter to use it. So you bring in your designer material and texture in Painter. They've pluged houdini to Designer, but you've painted in Painter?! Am I missing something?
  12. Ground, ground, ground, ... and ground again

    This is what I mean, 2 materials mixed using a circle as mask, the whole thing is being repeated, as if I have done nothing (or hopefully I'm doing something wrong) I'm talking about a grid or heightfield converted to polygon which then gets a uvtexture node added, that will be used as the ground in the foreground. I know how to texture terrains using erosion masks, but that's not what I'm talking about. It's just that grid/heightfield to which I apply texturehaven/megascans textures in the foregraound to sell realism.
  13. Ground, ground, ground, ... and ground again

    I'm missing something here: blending textures/materials happens in the uv space, right? seriously, is it right? because the screenshots below show clearly that whatever is mixed happens in that uv space. Now, if I increase the uv to 5 times, whatever is mixed is increased 5 times, so basically it is as if I have done absolutely nothing. I have a simple material white, a second in red, mixed using a circle. Yes, I can use any mask I want, fine, but it will be inside that uv space. I must be doing something wrong.
  14. I've managed to make the layer composite work, but now I need to choose exactly where the second material goes. I know I can use noises, but I'm talking about drawing/painting a mask where I want material 2 to be instead of material 1 in the layer composite.
  15. Now it doesn't even load images from COPs, it's a simple color node
  16. Houdini 19 Wishlist

    Option to overlay the network editor over the viewport, just came across this in facebook:
  17. Ground, ground, ground, ... and ground again

    If you can shade a bit of light on these techniques I'll be grateful. - using procedural shaders: do you mean like create a shader without any image whatsoever? I was hoping to make use of the realism of images (Texturehaven, megascans...). - blending various textures: I've tried blending various textures but the problem is the new blended texture becomes repetitive, it's the 0 to 1 UV space that get repeated. If I use uvtransform and scale it up, by default I'm repeating the 0 to 1 uv space, and my texture is assigned to that 0 to 1 uv space, so whatever I blend (unless I'm doing it wrong) will be repeated. Is there a way to make the blended texture appear on the second repetition and not on the first for example? - texture bombing: what is this? is it legal?
  18. Thanks, but I can't use cop texture in mat context. I write op:/img/comp1/OUT_MASK it doesn't pick it up, but cop to mat for a color image works. I have to export out of cops to disk, then import to mat, which is not how it's supposed ot be. Are you able to get a mask directly from cops to mat?
  19. This is a different question than the earlier. Ok, let's assume there is no way to paint a mask , and I have to live with the noises, to use them in the layer composite. I can do that, but I do not want the composite to be in the edges, I have a blue rectangle and that's where the composite needs to happen, outside the rectangle it should be red (no compromise, it must be red), and inside the rectangle I get the composite driven by noise or whatever as long as I don't have a hard cut on the edges of the rectangle (blurred transition). But layer composite should not be anywhere near the edges. Possible?
  20. I've started learning, trying to remember its name, yes MentalRay, with Maya, Before I'm done there was Arnold, stoped MentalRay, started a bit in Arnold with Maya (started on Renderman as well)), then I moved to Houdini and found Mantra, started on Mantra, then I see people using Redshift, they say it's way faster. Now I can confidently say I do not know how to use one single rendered properly, I've been jumping from one to another, like following fashion. Before I jump to Redshift, not knowing enough about Mantra or any other renderer (Oh by the way, Mantra will go away, there is Karma coming), I'd like to know if it makes any sense at all for a laptop user with only one video card: Nvidia (GeForce GTX 675MX, 4GB)?
  21. The color texture doesn't have alpha, there is a separate opacity map (black and white). In the principled shader I can see the "use texture alpha", but that assumes that my texture has an alpha which is not the case. While waiting for Side FX to add a convenient "use opacity texture", how would you plug this texture in the complicated network of things in the kitchen of the principled shader. There is a video showing something like that, but it dates back to the shops days, I couldn't follow, the network has changed.
  22. Ground, ground, ground, ... and ground again

    Great, thanks a lot, this has really helped. Just a question: from this angle we don't see much of the repetition, as the camera moves up, the repetition is blatantly obvious, how do you deal with repetition (even seamless) in the texture map?
  23. I need adaptive polyreduce: more polygons where there is more detail, and less polygons where it's rather flat. A bit like what the remesh does when you select adaptive. Can I get the polyreduce to do that? because now it's all uniform
  24. Ground, ground, ground, ... and ground again

    Apologies. my last question was a bit vague indeed. Let me refine it: That image I attached in the beginning, a guy looking at a landscape. So there is the grid and the heightfield. I'll attach it again. How do I merge them nicely.
  25. Ground, ground, ground, ... and ground again

    How does it fit in the scene? If I understand correctly I would use a grid, and apply Megascans using the bridge (don't know how yet, but I guess that's how it's done). Now I have a grid, with lovely ground, but it's a grid, displaced, it's still a grid. HOw does that fit with the terrain, heightfield, the scene? How does the grid merge with the rest of the environment?
