  1. Rigid Object using Grains (styrofoam)

    hey guys, is there a way to make a granular solid to be very rigid? Not cloth like. I have to simulate a detailed styrofoam breaking and it would be perfect if I could work with grains. Thx, Alvaro
  2. Hi, So I made an rbd sim where I had only 200 unique pieces. Then I made an rbd sim using 100s of each of these pieces. I cached the simmed points. After this, I want to place my unique pieces onto these points. What's the best and most optimal way to do this for the viewport and the renderer? I have seen many different techniques, I can't tell which one is the best. Should I just use Instance SOP? Should I save the first frame of the sim and use this instead? I can transform them using Transform Pieces SOP, but I don't know how to bring them optimally. Should the pieces be brought it as packed geometry, packed fragments, packed disk geo, or something else? I want Houdini to know everything is coming from these 200 unique pieces so it can show them more efficiently in the viewport and the renderer. I noticed if I save my pieces onto separate files as packed fragments, Houdini is saving the entire packed geometry onto each file that takes a lot of space. How do you do this? Thanks
  3. Dynamic RBD - Houdini to Unreal

    Would anyone know how to pre-fracture geometry in houdini, bring it into unreal engine and have it be dynamic (responsive to real-time collisions)? I know unreal has a way to do it and be dynamic, but Im wanting to be able to art direct from houdini for the area where my collision will happen in the level. I have already tried pre-fracturing with voronoi and exporting as alembic and fbx but no dice. Just wanted to see if anyone had a solution to this. Any ideas?
  4. FEM object to stay rigid

    How do i make a FEM object stay in air like its static but also take a punch and deform like its (Rigid) affected to gravity.

  8. Crowd dynamic distance ?

    Hello ^^ I always tweaking my vase scene with crowd but I have a real big problem: I don't understand why my vase reacts beforce my agents touch it :/ I don't really how to change the dynamic/bullet parameter in Crowd nodes tree :/ Please help me I'm kind of lost :/
  9. RBD and SOP Solver

    I am doing a RBD Fractured Solve. I want to use the Sop Solver through the Multi Solver to push and deform the objects to a final destination. I notice that when I transform the objects in the SOP Solver away from it's object center, it tends to do weird stuff. Like trying to still revolve around it's original pivot. Is there something I need to do to maintain a proper center pivot?

  11. Hello everyone, this is my first post here At the moment I have got a fractured geometry, a collision object that interacts with it and an animated bounding box that is activating the fractured pieces in front of the collision object. I want to have a procedural bounding box which is the collision object with a box that is plugged in at the bottom so that the bounding box adjusts on its own and I don't have to animate it. Can someone tell me how to do that please, thank you. Ground_Fracturing_B-BOX.hipnc

  13. Hello everyone I have got a sphere activating fractured geometry by going through it. I am using a foreach node with a centroid expression inside to add point to each piece which is then activated by the sphere via attribute transfer. Then I am using a point expression on a activevalue in the DOP to activate the pieces by the colour that the sphere transfers to the points. I want to know how to make the pieces that activate stay activated forever without deactivating once the sphere is gone. Any ideas? Thanks. activate_pieces.hipnc
  14. Hey everyone! I am trying to create a hailstorm effect with raining huge blocks of ice (hail). I set up a simple simulation where there is a grid and each frame a random point is selected and a hail is copied onto it, then with a sop solver it gets merged in. It all works, but after a few pieces, the simulation slows down drastically. They are packed and the DOP uses autofreeze, but still it's slow... Please somebody with experience look at it and tell me why? Thanks! Jegeso_001.hip

  16. Show what you made with BulletSOP !!! I'm creating this thread because I see that there is more and more R&D videos(mainly on vimeo) and In 2014 We can expect few great movies where artist's using BulletSOP push a limits of VFX. Of course these studio's will release breakdown's after these movie's hit Blue-ray!

  19. BulletSOP 2.0 beta_v5

    Hi, In attachment you can find fully featured BulletSOP 2.0 beta v5! BulletSOP is implementation of Bullet library 2.8(bulletphysics.org) inside SideFx Houdini. Its a plugin for creating incredible rigid body simulations. Primary it is single-thread application, but speed is very impressive. Memory footprint as well. The most important features of this release is that Its free and without limits(until now up to 5000poly objects). So now you can create real stunning massive simulations. This version is for Windows(64bit), Linux(64bit, gcc4.4) and Mac OSX(10.7), but OSX version is not stable on my system In attachment you can find example file with a lot of scenes, which are which propably the best learning resources at this moment. There is old tutorial(https://vimeo.com/57198443) for alpha version as well. I will make more tutorials for every node. And remember "Details view" is your best friend!!! Changes: - added motion blur output + example scene - faster Delete duplicity for constraints(2.6M constr. take only 4s) - fixed btLoader - added % info to btModify - few optimalization in btTransform Added new scenes: - building collapse scene(falling floor) - building scene with "snake" - high poly interior details on voronoi pieces - transform soft ropes with rigid bodies - added and changed few others examples LinkedIn group: http://www.linkedin....Houdini-4796605 Sneak Peek(alpha version): https://vimeo.com/57193837 Some info about this project: http://www.sidefx.co...wtopic&p=127978 Please, If you are interested in this project, take one minute of your time and fill this survey: http://obsurvey.com/...C4-71248188D81C Regards, Milan Suk EDIT: The latest beta v6: http://forums.odforce.net/index.php?/topic/17640-bulletsop-20-beta-v6/ BulletSOP_2_beta_v5.zip

For more info you can check my videos: https://vimeo.com/user3251535 I'm making more tutorials soon. And remember "Details view" is your best friend!!! In this release I mostly concentrated on object parenting and exploding convex and concave objects, because I received many question about that. Now It work properly! Changes: - added initial rotation for objects - added compound object(object parenting) - prepare node has many new features(padding, decomposition, ...) - fixed few bugs - ...

  22. BulletSOP 2.0 beta_v3 for Win64

    Hi, I want to introduce bulletSOP 2.0, which is new version of bullet implementation inside Houdini(surface network) for stunning rigid body simulations! It is based on Bullet phyics library 2.8. Primary is single-thread application, but speed is very impressive. On solver node is few option for multi-thread running, but its not so stable. When Bullet phyics library 3.0 will come, I will modify for GPU running of course In Attachment is fully featured beta version, There is only one limitation, you can create max. 5000 poly objects. There is no limits for other hulls(box, tubes, ...)! Full version will be completely without limits. For learning you can check this old tutorial(https://vimeo.com/57198443), but its for alpha version, so many things are different(better, easier). In attachment you can find example file with a lot of scenes(including sneak peek) which are propably best resources at this moment. I will make tutorials for every node as soon as possible. And remember "Details view" is your best friend!!! This is version only for windows 64bit. I will release Linux and OSX version in next few days! If you have problem to run this plugin on windows or its crashing, please write here. Othrewise with other problems, create new thread.
