Textures suddenly disaooeared from everything. Evcen windows became non-transperant and all utilities such as ovens become texture-less. Upon resuming to work again on the file I found out that all used texures were removed and I needed to download them again individually. Also, upon trying to correct for some structures such as staris, textures refused to appear on the object. I am realy frustrated as I needed weeks to design everything. Any help?
