hey so i always fun into this problem.

when i place a xmodel into my map not all of them hold shadows at a distance, its hard to explain really but when your further away from the model it does not cast or be cast on by shadows. its just lit by the worldspawn.

here is some pics to show what i mean (its a custom model but this happens with default models to)

Far away

here is a video from my previous map showing the same problem with the default models.

trie using shadow texture and put them where light will be blocked
