All downloaded - I just thought the promo images suggested there were variations for the colours - that deeper red, for example.

Ohh thought it could be the issue , it is the surface that can cause this effect with the lighted parts
so archiving these effects by positioning the lights casting hard shadows on the surface causing the
Light emitters to stand out 

 

Should there be a pose or materials folder for this? There's only props and no way to change the textures.

Just downloaded  the package and checked it ! All seems to be normal texture folder is in the zip
and when loading the textures are applied.  there is the texture folder with 31 textures geometry folder with the obj and the Props folder with the portal . All loaded just fine after I tested it again 

are you sure that you installed all the folders including the texture folder in your runtime ?

It is just the portal static prop in this package no other files

This looks  great. I will wait for 1st to get it. And also wonderful other freebies, Thas space medieval ship looks great and car also
