Hello! I'm quite new to Houdini, and I'm trying to create an environment. The biggest problem is performance, since it constantly fills all my ram (64gb) When I scatter the elements with low poly and low density, the scene kinda works, but if I add higher version of the objects, it just fre...

With the help of both the Redshift community and resources here, I finally figured out the proper workflow for dealing with Redshift proxies in Houdini. Quick summary: Out of the box, Mantra does a fantastic job automagically dealing with instanced packed primitives, carrying all the wonderful...

Hello all, I have a built a rig that allows for the dynamic simulation of trees. I was able to define an instance point which is offset from the trees branches. This enables the copying of a packed leaf primitive onto the point. The next step is to update the rotation of the packed primit...

Hi everyone. I'm trying to create a setup that instances a few models randomly as vellum soft bodies. I want them to spawn four at a time, every twenty or so frames. I'm almost there I think- however my current solution involves using a switch that picks a random model based on time, so I always end...

I'm having trouble figuring out the best way to achieve something. I'm creating a wall of bricks. Each brick will later be replaced by a far more detailed brick. I'm trying to keep my scene as light and memory efficient as possible so I'm using copy to points and pack and instance is checked. Ho...

I would like to input Maya geometry into the HDA, which then will do it's magic, like placing that 1 geo 100 times, and then instance it when baked.

Hello, I recently went through Steven Knipping's tutorial on Rigid Bodies (Volume 2). And now I have a nice scene with a building blowing up. The simulation runs off low-res geometry and then Knipping uses instancing to replace these parts with high-res geometry that has detailing in the break-...

Hi forum! Seeking out some help here, cos I can't get my head around generating vellum geometry. I am working on a scene where I need to create close-up splashing water droplets on a static surface. Typically this would probably be a FLIP task but it seems like overkill and I am only after a c...

Hello, I am currently working on an HDA, which allows me to place different objects on points using the "unreal_instance"-Attribute. Meshes and Particle Systems are placed at the right place. The problem starts with BP-Actors, they are placed without the world offset but rather at the 0/0/0 world...

Hello everyone! I am trying to do a simple thing but it seems like I am missing something. I want something similar to this: But instead of controlling it by pscale, I would like to take the bounds of my instancing objects and make them get away from each other if the bounds of...

Hi guys, This is noob question but I just can't figure it out. I have a pyro cache in the scene. All I want to do is to intance that obj node and transform a bit and scale it up. I've tried using Instance object but it seems I can't rotate or move it. Can anyone help? Thanks!...
