Houdini Engine for Unreal - Version 2 March 2, 2021, 5:10 a.m.

Hi dpernuit thanks for reply!

Weirdly I was just prepping the scene for upload and somehow it's just started working now. I just put a switch in there to choose between the input of a heightfield in Houdini or the Landscape in ue4 to see the difference.

What was happening is when I chose the Houdini heightfield it would work ok, but when I used the landscape from ue4 it was giving the error. In ue4 I was using a painted terrain layer called 'Base' (with some road splines writing into that layer also) And then in Houdini using that as a mask to stop 'stuff' happening there. Since I put the switch in though it's started behaving itself

I'll put some screenshots to give an idea though.

1) The Houdini graph, 2) input terrain and 3) processed terrain

Anyone else having trouble with terrain since using v2? I did some work with it in v1 but now just adding a landscape input into an erosion node is enough to get an error message upon rebuilding. Also all the old HDAs I made don't work either when there's erosion involved.

Weirdly, opening the HIP file in Houdini from within UE4 (nice feature btw) I can see the result of the erosion and it looks fine. It just doesn't appear in UE4.

Did something change in the setup?

Landscape Splines Feb. 25, 2021, 5:57 p.m.

Hi, is there is there an eta on when Houdini Engine will be able to get hold of landscape splines? I did read somewhere that it was in the works, my question is when that will be? I think it would be a really cool feature to be able to take advantage of.

cheers - Aten.
