I managed to do this by exporting an Alembic file from Houdini…and then importing Alembic into UE4 using a Geometry Cache input setting. So fun!
This video helped me understand why Alembic is so powerful and perfect for this kind of mesh deformation:

Is it reasonable to create a procedural mesh like this growing tree generated by an LSystem into UE4? I believe HDA's are for baking static meshes in the editor. So would I use FBX/Alembic animation? Or will that be impossible to texture/UV nicely anyway?
Just looking for some basic direction or if I should abort this mission and try something more realistic.
Thanks

Thanks for following up Doug. I have since learned about UE4's native foliage system and it does indeed do what I was hoping to do with Houdini workflow. Placing by hand is not so bad for smaller scenes…and I have been using UE4 procedural foliage spawner for larger areas.
The Bake to Foliage sounds very promising. This could be a nice way to generate variations of a Houdini procedural asset within UE4.
And also good tip on the HoudiniEngine for UE4 forum. I will poke around there too.
Cheers!

Houdini for Realtime » Mapbox not loading terrain data

Hello,
I used to be able to use Mapbox to download terrain data. Now it is not working for me. I am using Houdini Indie 17.5.173. I am pasting in API code from website, navigating to map location and pressing download. It waits for awhile but then nothing loads up. I waited for a long time to make sure my patience wasn't the issue! Any ideas?

Houdini for Realtime » HDA Terrain Scatter in UE4

Hello,
I have created an HDA of a terrain and some scattered points that contain primitives. Everything loads up nicely in UE4. I see the object scale variation created by the scatter node reflected in UE4. I also know about the ability to create additional instances using the Instanced Inputs in UE4 to create even more variation among the instances. But is it possible to control a single mesh/point in UE4? Or are these packed instances forever bound to each other? My goal is to get the general layout of all these scattered objects in Houdini…but then be able to nudge and fine tune the position and scale in UE4.
