I can use models I guess. But why should that be a work around? Is every terrain considered a block of memory that cant be fully recovered?

After doing this test: I can create an .mdl file using ent_create, then ent_purge and remove, and i can regain that memory the entity used up. But if I ent_create a terrain, and ent_purge and ent_remove, the texture memory is never fully recovered.

A workaround here is just to have all your terrain placed within WED and never created.

UPDATE:

reloading a level (level_load), over and over again, with or without terrains is causing me to run out of memory
