  1. [Vellum] Dynamically disable external collisions

    hey Geoff! Sorry but got extremely busy. That's sweet , thanks!
  2. [Vellum] Dynamically disable external collisions

    Hey Guys! maybe not too late to ask, but how would you approach allowing one of the strings to collide with one tube, and the other with the other tube only ? So Line A wibt tube A only, and Line B with tube B only? See attached selective_collision_release_Fra.hiplc
  3. Source Volume Collisions in POPS

  4. Source Volume Collisions in POPS

    Hi guys, I have done a lot of research on optimizing my collisions especially becausee with high res volume colliders as DOP objects I usually feel like it's slower than it should and sometimes also have memory issues. I was wandering if the Sourcing of Collision and CollisonVel attribute workflow can work in POPs and Grains? I Feel it should, and i can see the volume when i plug it but no collision both with the old and new volume source dop node. I can attach a simple file and maybe someone can give me a tip? Thank you Frankie ParticlesSourceVolumeColl.hiplc
  5. Sweep orientation issues

    Hi, from the picture it appears as it's just the natural way Houdini presumes what is in and what is out, if you really wanted you could selectively make a group of the faces you wish to reverse and use a reverse sop. Alternatively, you could just slightly polyextrude internaly with the "output back" option enabled, this should remove any visible backface. Best Regards Frankie
  6. Camera Projection from Moving camera

  7. Is it possible per-pieces scaling?

    Run into a foreach with this expression in the pivot translate "$CEX $CEY $CEZ" of a trasnform, or in a primirive sop with "do trasnformation" enabled . Then you should be able to trasnform each primitive indipendently! Best regards Frankie
  8. Camera Projection from Moving camera

    Hi there, I have been scratching my head about how to project a texture form a moving camera that gradually reveals the footage onto a deforming. Everyting good and easy if the camera is still, but the problem arises becasue this particluar shot has a long back dolly close to the ground so i guess i would need to project all the frames of the said plate onto it. In other words, in frame number 1 you can not see some part of the plate that you can see in frame number 100. How would i need to approach this problem? Mny Thanks Frankie
  9. 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!
  10. 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
  11. Get the pointbumber of points in a group

    Thank you guys!
  12. Hello everyone, I am trying to get the number of points in a group with the pointlist fuction, but having it erroring. If you can help me out it would be much appreciated. Thanks Francesco Pointlist.hip
  13. Custom AttTransfer With Effector in Vops

    Hello everyone, I was wandering how would I need to approach the need to trasnfer an attribute, say N, from a geometry to and identical one with an effector or some sort of object which position determines where the attribute is transfered. When the transfer is from an A to a B object, the solution is a pretty straight farward classic Attribute Transfer Sop, but how about the A to B through C scenario? I have found an easy fix with Sops: boolean substract a sphere form a grid A, copy the normal attribute from grid A to the product of the boolean then attribute trasfer from the product of the boolean to the B grid. Still this is very intricate and culd easily get superslow when dealing with more complex geomety, how could it be build inside Vops using some sort of geometry as bias/effector? I shared an Hip with what i achieved so far Thank you for yor time Frankie ATTR_TRANSFER_BY_EFFECTOR.hiplc
  14. Sop Solver Dilemma

    Victor to the rescue again! Thank you very much man! I was so close, i am missing what you changed in the SOP level tho
  15. Clusterin Pyro on the y axes

    Grazie Andrea! I will defo check out the masterclass again, i had a look at it a while ago now, thanks
