  1. Hello guys! Can I ask U question, Im very new in houdini. Can u help me please? Im trying to render short video of volume (smoke) in matra, but I really do not know how to set the mantra settings, because one frame is mantra creating for 43 minutes, which is rediculously long time for 250 frames. can U help me, with settings? I already increased the Volume step size, but thats all what I did, (I read somewhere its helpfull) is there any other way, how to make render time (per frame) shorter? Thanks a lot for any advices! Im looking forward to your re´s! By! advice.hip
  2. Ramp between three textures - REDSHIFT

    Thank you so much!
  3. Good evening! Can I ask U guys for advice? Im trying to create ramp between three textures (but with same uv map), defined by paint SOP on pighead testing geo. And what I want to ask U is: Does it possible to somehow assign different textures for each color, in redshift? Any advice will be very, very helpful to me! Thank u guys so much! textures_issue.hip0.hip
  4. how to reduce waves???

    Fixed! What I had to do was, just create another group of points (all points-vertex from heart) and plug this group into Struts>Geometry>Group. now it works!
  5. how to reduce waves???

    Hello guys! Short question, how can I reduce waves of the vellum structure. I wanna make a simulation of beating heart and its still very weaving. Also it looks like that the vellum struts are "under cloth"..... :/ Is there any reason how to fix that, or I have to use FEM only? Thank U hor any advices srdce.rar
  6. TINY TRAIL ISSUE

    Thank U so much, I did it with the Life Expectancy (set from default 1 to 10). Now it works perfectly as i needed!
  7. TINY TRAIL ISSUE

    Hello people, im trying to make a poly-line from series of points. Everything works perfect (picture_1) BUT every time when the simulation reaches frame 44 the lines close its rows, (picture_2) and I dont know why. Can U help me please fix this issue? Thanks a lot! ISSUE.hip
  8. fibers on surface

    Hello Houdini guys! Can U help me please to get result, something like here in the pictures down here? What I need is to get fibers (curves or poly-lines) on surface of my generated mesh. I already tried something (very short and quick), but it doesnt work very well, and I really do not know how to fix that. Mainly, it doesnt work in small parts of the mesh, and sometimes doesnt work the Ray node very well. I will be very pleased for any response, or advices! Thank U! FORUM.rar
  9. how to import point (attribute VOP)

    Hello guys! Can U help me with small problem? I dont know how to import all of the points from scatter to attribvop (to get to an same gradient for all of them)?? Can u give me any advices? Thank you so much! hip. hile in attach how_to_import_all_points.hip

  11. physarum polycephalum / slime mold PROBLEM(s)

    Ure awesome! It works! Thanks a lot Victor!
  12. Hello houdini guys, Im trying to simulate physarum polycephalum growth, but unfortunately it has some small issues. I would like to ask U on 3 main questions, if u will able to help me with any of them, it will be very helpful for me! 1. I have problem with VDB convertion as U can see on the picture, the distributed mesh (from wire extrude) is broken and VDB looks like particles. I dont know how to fix that. 2. In my file (I marked it with red network box) the small vein system of my slime mold, and I would like to connect it to the growing solver, but I dont know how. Basically I need this small veins with same growing properties like the big one have. 3. And last one is is possible to make the slime mold more "fat" on the edge? I dot hnow how to select this part of mesh? :/ ( like onreference picture) Thank U guys for any advices! Im looking forward! Bye! Physarum.hip
  13. How to Render to Disk with selected region?

    Oh! thank You so much! So easy, I didnt know that!
  14. Hello Houdini people! May I have a simple question on U? Im trying to make a render of extreme difficult scene, with a lot of lights and textures with redshift. But unfortunately I can let rendering my computer only durring the night (because durring day I need it for my work ). The render which Im trying to make usually takes almost 20 hours, but as I wrote when I need the computer I have to stop it and then start again, because the render is unfinished (in corners because the buckes didnt finish it there) and also its unusable. What I need is lets say select some part of camera view and render it (RENDER TO DISK !!), basically I will divide whole frame on small parts (each part per night lets say) and then I will put them together in photoshop. So my question is: Is possible to select region in camera view (for example like in Blender/Cycles: its Shift+b+LMB) and then render this selected region to disk (I do not want render in scene view)? Thanks a lot for any advices!! Bye!
  15. Organic Mass problem

    Ok, so let me apologize, for my stupid questions. Im sorry! I really appreciate your advices! Im quite new in houdini, and I still do not know how it works in 16 and also 17 then. But can I just ask you, how can i add wind force (the turbulence - because in velum solver i cannot set turbulences, but only one vector direction)? I tried to analise your file almost whole night but i still do dot know how to make my geo (heads) in simulation, stiffer.......
