LOl some dont even know melee maps ( reply 1 about high quality textures) from too much mapping, not to say if you know melee games and not to say solo hahaha green peon : 'what is solo ?????'.
Thats easy to asnwer, i use 512 MB Ram, ge Force 4, direct X 10 +, 2 GBs free space you see enough for frozen throne running fast and properly. I know that melee maps have thousands of doodads => 3000-4000 doodads may not cause probmes havent tried with more.
BUT:
Units can cause you see even with that space your map to crash. You can have like 100 units or 200 (risky) but more will kinda cause all to crash. I already showed you what im working on. Well i used to have some fences as buildings, i made them destructible eventually. I was thinkink of making all the civilian buildings units but as you see to many buildings will cause a FATAL ERROR. SO my advice when it is not so important like this here, better use doodads with these models. Ok i might try when i have my models done, to add as buildings but believe me i have done it many times and too many units= crash. At least 300 + units is crash
Note: a better chance not to crash is not to add them one by one but to add them with triggers. Create X unit .... This reduces but doesnt comepletely save it from crash.
