Hello im working on a model for the new catenary and i make the nodes for the catenary in 3dmax i have a node 1_0500_Contact a node 1_0500_Return these two i grouped in S1Pull.
so i know that i cant export these, therfor a make transparent pane i caled 1_0050_Contacts. i made S1Pull a child of 1_0050_Contacts and export these but when i make a scenery blueprint of this then i canot see it in the preview window or in the game it self i made it vieweble in the blueprint. this blue print is nessasery for a ganrty to put the catenary on. first of all i have to make this work.
does anywone have a idee how to solve this ?

Many thanks Tankje(Rob) dutch content builder.

I have an idea what could be causing this problem, but I can't remember it right at the moment, I'll preview a blueprint tomorrow to see what it might be.
