Hi,

Sorry to open a new thread about that subject…

I have an Houdini Terrain brought into Unreal via an hda. The layers show up in the unreal landscape as expected. It seems im not gettin correct layerinfo when i change the simulation frame (erode) which is promoted in my hda.
Is this a known issue ?

a tutorial about the Houdini terrain - hda - Unreal would be really helpfull.

thank you.

Hi,

Changing the frame parameter won't work via Engine.

You need to use a Timeshift node after the Erode, change the frame parameter's expression so it's not set anymore to $F, and expose it as a parameter on the hda. You'll then be able to change the erosion frame in Unreal.

See the note in the docs HERE [www.sidefx.com]:

Hi,

Sorry my post might was missleading. I allready did so. TimeshshiftSOP after erode and promoted the frame integer in my hda. update of the heightfield works, but layerinfo like debris, water a.s.o. do not.
