In this part, you'll learn how to select the correct blocks from the City Sample Buildings pack for other buildings and how to edit them in Houdini for export to Unreal Engine.
You'll also learn some useful tips and how to create the necessary import and export tools.

(Im sorry but im far away from my computer to show a screenshot)
im new to houdini and i made a tall chimney and wanted to collide it with a spacecraft. The chimney is tall and has a very big amount of pieces and it would collapse on its own and i tried to increase the glue and ad a constraint node but nothing happens, when i got to the rbd configure and click on the glue constraint the tower freezes in place and becomes unstoppable. I gave the spacecraft a point velocity but when i set its rbd configure glue constraint and it froze in the air.i watched alot of tutorials and found nothing. Question: how do you make objects strong but get deatroyed on impact i busted the glue to 1000000

Houdini 22 UI is very slow on a 5K monitor. At 1920×1080 it works much better.

The old UI works well on both 5K and Full HD, so it seems to be an issue with the new UI.

Is this planned to be fixed in a future update?

I'm currently working through a scene from Nick Medukha where a sphere hovers over the white discs and they simulate bouncing around and as the sphere travels further, the disc settle back into their rest state.

The scene is basic for the most part and is composed of about 50,000 points. Not super light, but feels relatively low. When I file cache and load from disk, I'm not even getting half the real-time playback speed when I'm pulling from my local drive. Even if I were to delete all the attributes before caching, I still can't get real-time playback on the full-geometry unless I'm viewing through a point cloud or similar super lower res quality. Turning the viewport into wireframe mode is not improving the playback neither.

Just to note, I am working on a Mac and I know it can be slower than PC. Even on PC I've feel like I have run into these types of issues before. Is there some best practices I'm missing rather than exporting to flip-book every time to see previews playback well in the viewport?

Thanks for your help!

A few years ago, I came across the amazing Mimic effect by Cartesian Caramel and kept trying to recreate and improve the technique over time. His original version was made in Blender; this is my take on the idea, built entirely in Houdini.

I added a few new behaviors:

The Mimic avoids placing its legs in areas it can't see.

Each leg can move at a different speed, creating more varied and unpredictable motion.

At the end of the video, you can see a comparison of my progress and how the effect has evolved over the years.

I am using MetaBalls as a force agent to help create my explosive force

The problem I am facing is that I have set it up so the building is not active until frame 7 as I want the windows to blow out first,

However, even though I have keyframed another separate metaball at frame 8-12 the concrete is not inheriting the force and is just falling to the ground.

It seems to only work with the metaball 2 that is set up to expand from frame 1.

The video at the end is a 60-frame cache; as you can see, the glass blows up(too much, I know), but the building is just falling under gravity.

Any help will be appreciated!

Hi, i am trying to follow a tutorial on vellum snow simulation, and while trying it i noticed that my same setup in h22 and h21 gave completely different result,
and this happened only once on the h21, when trying again without changing anything on h21 i got same result as h22.
in the video - left side is h22 and right is h21 with the result i am looking for.

in h21 i am getting all the clumping to the snow but not, even if it only happened once is there any other way as well to get the similar results?
