I think using HE to point scatter those Nanite SM which are already imported in UE5 would be a great workflow to create stunning environment.
Houdini Engine for Unreal » Landscape tiles output not working for UE5 World Partition

https://github.com/sideeffects/HoudiniEngineForUnreal-v2/issues/143 [github.com]
Understanding UE5 is still in Early Access, and HE does not support UE5EA officially yet. I have tested outputting Landscape tiles with World Partition at UE5EA.
With unreal_landscape_tile_actor_type = 1 and no unreal_level_path set, it generate one SharedLandscape actor with one StreamingProxy.
ie. with 16x16 tiles, it generates 16x16 SharedLandscape actor and 16x16 StreamingProxy in total.
The behavior is different as it was in UE4 and it looks like it is broken in UE5EA with World Partition
Anyone got UE5 World Partition working?

Currently, I only tested it to load Megascan 3d assets for Mantra successfully, but nothing else. There are other modifications (especially for renderer other than Mantra) that I would miss. I suggest we all work together to update the Megascan Houdini plugin that works the way we want!

Maybe something like an OnCreated script to guide you to download and install the proper Visual C++ Express version if the node is dropped down the first time on Windows. Much like how the NVidia denoiser is setup for Mantra, I think.

Thanks. I didn't try the point cloud data structure in CGAL yet. I just cherry-picked several CGAL algorithms for a project I am working on.
Yup, a native C++ Wrangle SOP is nice and your node is awesome too. However, the users still need to setup a proper dev environment for compiling (at least at Windows) which might be confusing for some users.

Integrated the 3D Straight Skeleton algorithm in CGAL, using the inlinecpp Python module. The inlinecpp Python module in a Python SOP is almost good enough as JIT compiling as a Wrangle SOP for HDK.

Technical Discussion » flip air incompressible instable

running a sim sinking a ship in a tank.
the new air incompressible gives a lot great detail.
however, the sim explode randomly at certain frame. the ship is a very complex geo, but the animation of it sinking is fairly gentle though.
I also ran another with air turned off. It ran through fine.
what would cause the sim instable with air turned on?

Technical Discussion » vel vs collisionvel , and staticObject node's collision and source volume node's collision
-
- kelvincai
- 74 posts
- オンライン
Static Object works for all solver. Source Volume works only for the solver the volume plug into.
Static Object, if deforming/translating, takes the trajectory into account, while Source Volume is not.
Static Object takes physical properties ie bounce, friction, etc, while Source Volume doesn’t.
vel is used for advection, pressure solve etc. collisionvel is only for collision detection.
Hope this helps.

Yes, it is just a matter of turning on viscousity and having the temperature attribute affecting it.
Check how the Lava shelf tool settings are. And, change the flip tank accordingly.

Ocean Spectrum doesn’t interact with collision. However, you could mask around the islands with another spectrum to fake the reflection waves, then sim whitewater in top. Or, use Guided Ocean Layer to do a flip sim around each island, which you will need Houdini FX.

the Age POP is for the old popnet.

if point number is changing every frame, and there is no consistent pid attribute, you could use velocity attribute to advect partial frame (assuming velocity attribute exists)

1. You need to save new cache files out whenever you change your sim
2. Yes, the visualization is only for the viewport
