  2. Hello; In a font SOP, is there any way to use "Persian" or "Arabic" fonts in Houdini? Thanks.

  4. smoke trail render

    Thanks,I will try.
  5. smoke trail render

    Could you recommend some tutorial about this?I can't find any of them.

  7. Normal Force in Dop

    Hi i couldn't figure out how i use multiple geometry vop in dop. i have two objects which have different force direction from normals but i can't get both direction force. i need help please. normalForce.hipnc
  8. smoke trail

    Thanks Andrii
  9. Bahahah, I understand. Ive kinda given up on it and I'm still thinking about how I can solve it, just seems interesting that no one's asked it. Thank you for the huge help I'll give it a go
  10. Smoke density based on ramp

    Hi everybody, I am new to houdini and i am already scared. I know how to emit pyro from colors by using ramp than a delete node with a $CR < 0.1/.5/.8. on my emitter it work but i want to control the "density" of the emission based on the gray level of my ramp/paint node. Meaning white zone = 100% emission dark zone = 0% thanks you
  11. FOUND an OPTION to rotate the Fluid Tank. It works with *Fluid Solver *fluidconfigureobject *fluidobject Only.... Dont know how are you going to USE IT IN OCEAN. I dont even have time for that right now. But you can DO SOME RND bud. Add a "fluidobject" and add a Position Node and in the Initial Data tab "Position Data Path" plug in the path "../Position". Also Rename the position node to "Position". This way is NO LONGER USEFUL since the Flip Solver is introduced. Still dont know why I'm POSTING THIS. LOL
  12. Is my GPU no longer supported? Houdini 16 works fine on my system but no go on version 17. No crash reports generated in tmp AMD FirePro D300 OSX 10.11.1 Here is a pic of what happens each launch. https://drive.google.com/open?id=1EZcH_Ea9CQ75KMTJP6wEDeYgwWc7kghX
  13. Hi Odforce, I've got this funky track that has a curve as path for this rubber-thingy. Im trying to get it to follow the path along its normals. But its not working along at obj level. Probably its something very basic. Hope someone can help me out. Thanks in advance, Marco Track Parent allong curve.hipnc
  14. Hi guys, I have trouble with selecting multiple primitive groups inside the group delete sop. I can only select one primitive group at a time where sometimes I have hundreds which takes ages to finish. I did tried to use Shift+Left Mouse Click, Shift + Space+ Left Mouse Click, Space bar + Enter and so on. But none of these works for my purpose. Please help me with that.
  15. problems with collision and alembic

    Try disabling the geometry visualization to better see if the actual collision gemetry is consistent as a first step, it is possible that there is a discrepancy betwheen the two!
  16. Cut a moving object with solver ?

    Hi Antoine, to continuously remove parts, it's more reliable to do the subtractions in a voxel field rather than immediately on the mesh. saw.hipnc
  17. Redshift users, post your tips tricks here please!

    Hey everyone, I think i need some help with volumes rendering I am building a scene which has both neon lights that create a nice neon-like foggy look and regular pyro volumes. I was wondering if it was possible to selectively activate the “volumetric scattering” options in the Redshift Rop in order to make only some of the lights in the scene create the said foggy look and still have regular volumes render as normal smokes etc. Thank you for your time Frankie
  18. Cut a moving object with solver ?

    My problem: simulate a table saw; object come to one side of the blade and ends up to the other side of the blade with material removed where the blade touched the object. My strategy: boolean subtract the blade from the object at each step of the trajectory.
  19. Genetic Algorithms in Houdini

    I am not sure if this is the appropriate forum. I recently wondered how hard it would be to implement genetic algorithms in SOPs. The particular example I was curious about was if I could turn a box into a sphere by optimizing for a target function that maintains volume but minimizes surface area. Overall, this was easier than I thought and did not involve all that much code. I ended up recording a video that explains this: The underlying motivation was to get this working in PDG but I figured I had to start with SOPs first. Let me know what you think.

  21. Cut a moving object with solver ?

    @AntoineSfx Make your box a softbody ?
  22. Cut a moving object with solver ?

    I don't quite understand your strategy or your problem. Please post a hip file.
  23. Buttons_list_add does not exist error ?

    Could you fix this error? I just installed Houdini for the first time and encountered the same error... Thanks
  24. Cut Copies

    Thanks guys I appreciate the help!
  25. I have a keyframed animated box and a cutter (a smaller box) on its path. Using solver, I don't manage to have the cutter remove stuff from the animated box using only previous frame and the cutter. I managed to do it like this, but I wonder if whether it's a good practice or not: I got the transform from the keyframed box using a matchsize to move the previous frame.
  26. I think it depends on the render you want to use. But anyway, you're going to have to use TP. With 6 million particles, it's not really a good idea IMO. Also I think I remember that it is imperative that there is at least one particle from the first frame in the alemebic file.
  27. Frozen Particles

    thanks for your help kleer001 I will apply your advice to optimize the piece. I tried to disable resize_container> Max Bounds> Clamp To Maximum. But the particles are still freezing. The only thing I try to achieve is that the particles that freeze when they reach the top fall with the others. The rest seems fine. Sorry for my ignorance, to apply the Alpha do I need a SOP VOP? How can I do to use it? This would not make disappear all the particles of the base that do not move? I try to get something similar to what Simon achieves in the second 14 of this video Thanks again
