I am working a major map expansion to my game and it has caused the memory to go up from about 500MB to 1800MB.
I want to lower the memory but i have run out of ways to lower it any more.
I have managed to lower the memory to about 1400MB but in still not satisfied
I have compressed textures and deleted unnecessary objects and enabled streaming.
what other things can i do to lower the memory?
Have you removed as many unionations as possible, and erased unnecessary terrain (terrain that is not visible to the player, such as generated that makes a big block that you could shave down)?
Sounds good. You can also use the Decimate geometry tool in blender by going to Modelling > Mesh > Clean up > Decimate Geometry with the item selected, then adjust the ratio. I’m not sure how well it will help you but might as well give it a shot. You could also possibly change the track bottoms to a texture, and just let the part pieces be the two rail lines to give it a bit of three dimension.
