You just need to have the different variations of the traffic lights in the same file, like what I did with the sign pack.
Hey Pedropp222... I installed your signs, but on my system they showed up as separate entries in my asset list, not as a folder (which is a much more efficient presentation)
(Maybe I downloaded an early version?)
Can you direct me to a link for an installer that will put all of your signs in a folder? Then I can clean up my asset area by removing all of the individual signs
( never mind. I found a link for your updated signs but my virus program throws all kinds of red flags on that site so I'm not willing to DL anything from there)
Thanks to everybody who helped to explain this topic. I actually got similar results with FBX, but in a different way:
I created one generic sign, then copied the MTL and OBJDEF files for that first sign and edited them to add new sign textures. For each OBJDEF file I got a new entry in my folder. In my case, the signs all have the same shape (rectangular)
Naming convention for the files was as follows:
park_signs.objdef, park_signs.mtl
park_signs1.objdef, park_signs1.mtl
park_signs2.objdef, park_signs2.mtl
etc
when I named them differently than the original, it didn't work.
Just 1 PKG file, from the original sign.
