In my map some of the modesl used looks really out of place they appear to be foggy when far away and when walk close to them they are normal i think this is due to the fog used iam not sure heres some examples of what iam talking about:


as for the fog iam using in the map its:
_fog
textures/skies/sd_batteryfog
fogclip
3200
also other stuff ive used in worldspawn that may help:
_color
1.000000 0.962463 0.712261
__minvertexlight
18
_mingridlight
56
not totally sure what they do but was told to add by someone ages ago 
i also have a fog shader that acts as water in my map as the islands float in clouds, hence the name battle of wolken.
anyway if can can give any help on now to solve this i’d be very gratefull as my map isnt
exactly looking any good with them as it is.
EDIT doesnt happen on all models just a few.
