  1. underwater growth effects?

    Of course I hadn't thought of simplyfying it down like that at all! I will try that thank you!!!
  2. underwater growth effects?

    Thank you for your reply! I just need the final geometry, it doesnt need to grow over time in the actual shot (this is for a small group project). I've done some floating debris which is quite convincing. I'm not sure how to approach the hair stuff? Would that be groom or a constraint network or something? I'm also doing sand build up for the surfaces which will help.
  3. underwater growth effects?

    Hey guys, it's me with another noob question! I'm trying to create a kinda corally/spongy/flowy growth effect that would happen underwater. I've stalked the differential growth topics and have created some sims that look like they could work, however when applied on big complex geometry it just isnt feasible to have that many differential growth going at once. Am I thinking the wrong way here? I feel like I am not approaching this correctly.
  4. How to constrain object between two others?

    Hi Benne, thank you so much for your reply! However, I'm not really sure what I'm looking at? I see that is I transform after the merge they will all have the same animation, but I have been given an alembic that already has movement. I'm trying to parent a sphere to the hand so that it moves with it but I'm not sure how to do that, coming from maya the most logical option was to parent but I don't really know how to do that...
  5. Particle movement and collisions?

    Thank you so much for your response! I think its a problem with the collision object, I've already extruded it and used concave geo, but I will check the normals cause that might be it! For the buffer thing, I will try to use a POP Steer Obstacle as it seems to be exactly what I need.. Let me know if you do take a look! Thanks again
  6. Particle movement and collisions?

    Hey guys! I'm trying to make some floating particles inside a geometry. I need the geo to be a collision object and the particles to kinda have a buffer area before they touch anything, not very obvious but enough so nothing actually collides. However, I'm having trouble getting the particles to actually treat the geo as a collision object, and also stopping some of the random ones that like to go super fast. I thought that the popspeedlimit would the trick for the fast ones, however, it kinda clamps the whole speed of all the particles, rather than clamping the velocity of the fast ones. Anyway, here is the scene file with the alembic, if anyone has an idea of how to fix this please let me know! underwater_particles.009.hipnc blockoutForSim.abc
  7. 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!
  8. Floating Particles in Water?

    Ah thank you so much! I can see I was running along the right lines I just don't have the knowledge of houdini yet to know how to actually put it together haha! Thank you again, you've definitely steered me in the right direction
  9. Floating Particles in Water?

    Hi there! I am currently a vfx student and very new to houdini! So far it's been tons of fun but I've come across a problem, basically I want to create particles like algae and dust floating in water, but I'm really unsure what the best way to go about it is. Originally I was just going to do a very basic particle sim with some currents going through...but that didn't really work out. So, how do I approach this? Any little bit of help would be greatly appreciated!
