  1. Hey Atom, Thanks for taking a look, I didn't know that about merge nodes or the object merge, so that's really useful! However, the problem was persisting once I added back in my other pops and popwrangle. I eventually worked out that the problem was coming from the wrangle, it was setting the max pscale to 1.3, which was way to big for the scene hence the instant collisions! I hadn't noticed because my geo was copying onto the particles at a decent size, but that is because it was small to begin with. However this is now fixed!
  2. Hi, I'm trying to collide some particles with a simple collision object and a ground plane, however whenever I enable the collision objects in my scene the particles seem to be colliding in midair instead of with the objects. The collision preview looks fine and I've tried adjusting the collision tolerance of the particles but to no avail. the sim works when I bypass the collision objects. Any idea why this could be happening? sim.zip
  3. Hi, I have an RBD simulation that drops petals onto a piece of terrain. I've created a collision SDF for the geometry, but for some reason it is behaving strangely and the petals are colliding above the surface, even though the Collision Guide looks fine. Is there something I'm missing here? http://oi65.tinypic.com/2zrp2y9.jpg Shot3.hipnc
  4. Thank you so much for taking the time to look at this! This is really detailed and useful!
  5. Hi, (Disclaimer, still pretty new to houdini) I have a flip simulation that's intended to be a bowl of milk. I want the bowl to be full and to just settle until it's affected by outside forces, but the fluid just instantly collapses to a fraction of it's overall size, even with gravity off it just compresses in on itself. I've tried reading up on this problem online, and have tried various solutions such as disabling reseeding and enabling separation, increasing and decreasing the particle separation and grid scale, but nothing seems to work. Would someone mind looking at my file and telling me what i'm doing wrong? It's driving me up the wall and it's preventing me from completing class projects. Thanks, Richard Advert.zip
  6. Hi, Could someone explain to me why my DOP network isn't working? I'm not sure what's wrong with it, but nothing is interacting, even the gravity isn't having any effect. I'm pretty new to houdini, and in all likelyhood I've set something (or multiple things) up wrong, so if anyone can help me out it would be very much appreciated Thanks, Richard shed3.hipnc
  7. Hi, I'm pretty new to houdini, and I'm trying to scatter points onto and inside a moving character that I imported via alembic. I'm doing this via converting the geometry to a volume using isooffset and connecting that to the scatter node. I know how to make the scatter points stick to the surface of a moving object using attribute interpolate, and that works fine, but when I try this method using the volume it results in only a single point being visible. Is there any way to fix this? Thanks, Richard
