Hi guys,

I've been trying to set up custom low res collision geo with no success so far.

I haven't been able to find any documentation about this procedure other than that it is mentioned here
https://www.sidefx.com/products/houdini-engine/ue4-plug-in/ [sidefx.com] @~5:57

The lady mentions setting up a building_geo group to do this but doesn't got into further details. Does anybody know how this group is export/imported into Unreal Engine? Is this documented somewhere obvious I have overlooked?

Thanks!

If you have constant number of collision elements in your asset then this should be enough https://www.youtube.com/watch?v=FABVfxpUA44. [youtube.com] Otherwise scripting should help you(

Hi Fifty. Thanks, yes I have been able to import custom collisions in .fbx using the technique in the video you posted. I haven't been able to get this to work yet with .hda/.hadlc so I am thinking that the procedure is slightly different somehow.

I'm using Houdini Indie 15.5.542 with UE 4.12.5

Cracked it. In the end all you need to do is create a group named collision_geo and it should work automatically.

Yep, that's the trick. Here's another video that explains it.
