Why can't I get more space to make creations????
It has to do with fact that there's limits with how much you can put on the screen with DREAMS. And how you eventually run out of room.
Could I use my 2 TB HDD to unlimit the amount I make for my creations?
Can DREAMS use my whole HDD to make enormous games?
DREAMS only takes about 15 gb or more, so could I make my PS4 like a supercomputer?
I asked this on twitter. 1GB is the maximum Sony allows per game. It will not be increased. Never. Save as much as you can online.
Use the reduce detail tool on your sculpts to save on thermo usage. You might be surprised how much extra room you can get. There's other ways to save on thermo usage too.
Dreams has incredible compression and the online storage is unlimited so this really isn't an issue. Just save versions of your files as private and you can make a game as large as you want.
Even locally, 1Gb and 256 elements are a lot smaller than you might imagine. Unless its audio, It takes along time to fill up (though I have hit file cap which was more an issue than the space locally)
