Hello, I'm having some issues with creating a material set for a HDA in unreal 4.
I'm trying to get the system working on BSPs in Unreal, which are being exported out into the system via a operator path and a object merge.





However whenever the BSP models are used they break all of the materials, causing the system to revert to a single default material. This only happens with the objects from Unreal, I have tested on objects exported out onto the desktop then file merged, these work correctly ( even the ones that don't work in unreal seem to work fine when exported out then File merged).

I have linked the project below, the sections in question are in “Building base” and have been highlighted in red.
apologies if I give anyone who has been using Houdini for a while botherations with the general messyness, I'm still very much a beginner at this.

I'm still very new to Houdini and I'm almost certainly missing something here.

Thanks very much for any help, its greatly appreciated I'm tearing my hair out by this point
