  1. Edge Fracturing

    Hello houdini people, Im relatively new to the houdini scene coming from traditional modelling background so go easy on me! I came across a webinar from 2016 with Mike Lyndon in which he talks very briefly about applying a secondary frracture to already fractured pieces around their edges. I've attempted this with what very little skills and understanding i have in the software to this point but just can not seem to figure out how to contrain the secondary fracture to just the outer edges of each piece. I figured an approach would be to bevel the pieces and create a new group for this beveled area and apply the secondary fracture to only this group however i am not getting the desired results. I've attached a file with the approach i took and how far i got Any suggestions on achieving the effect would be much appreciated! Cheers guys and girls! Edge Fracturing.hip
  2. Hi guys, Im doing a simple fracture sim with rbdpacked object and constraint network and breaking few constraints dynamically. so endup with clusters of pieces as usual. Is there any way to get an id attr per set of pieces constrained together after the sim? Thanks in advance.
  3. Hi there! I have been given an animation to work on and I wanted to parent constrain a sphere between two objects so that it would stay in the middle of them during the animation. However, in order to parent constrain I apparently need to create a constraint network and I'm finding it really hard to find any resources for that. I just have no idea how constraints work so any help would be appreciated!
  4. Hey, In maya there is a parent contrain. It parents the rotation and transformation from one object to another. How do you do that in Houdini? I am confused, I see you can parent objects together and use the shelf tool blend. But they don't work, because the transformations are not at object level. Whats the point of having all these different constraints if your transformations are going to be made in sops and not object level? I am just trying to contrain a null to an alembic cache. Is it better to do animation a object level the geometry level? How can I get geometry level transformations into object level? Thanks
  5. Hi everyone I applied a cone twist constrain to an obj, and then when i'm trying my sim I can't play in the right way with the parameters. everything I touch my fracture just "bounce" instrad of breaking. I tried to change also the Physical parameters of the object, why this is not working? Thank you
  6. Hello I have a fractured geometry and I want to glue lets say every 3 nearby pieces into one to create more interesting pieces. I also want to do that in a procedural way, so that I will be able to plug any fractured geometry and it would still work. I don't have an example file because I have no idea how to approach this.. Any ideas? Thanks.
  7. Hi everybody, I'm looking for a way how to create dynamic constraints with Bullet. The basic way doesn't work. Take a look at hip file please to see the problem. Any help would be appreciated! Thanks! bullet_dynamic_con_issue_v01.hip
