I can't seem to get the bases for the adverts to show up. I can spawn them in world and place them, as well as change types and display the advert itself. But it is as if the texture for the model is completely transparent. The model is there and I can walk into it so collisions are working. I just can't see them..

Upon placing a block which also appeared to be invisible in Malisisdoors, allowed me to see through the terrain like an X-ray and I discovered that the model itself is actually rendered but in the incorrect position. It looks to be a good 30-40 blocks away and 20-30 blocks down.
