My advice is to give it the amount of GB (gigabyte) that your computer has installed physically, minus 2 GB. You didn't use the installer to install WorldPainterįirst, decide on how much memory to give WorldPainter.You installed more memory (in which case it is easier to just reinstall WorldPainter).Note: the WorldPainter installer already configures WorldPainter to use the recommended maximum amount of memory! These instructions only make sense if your situation has changed or is different, for example: This page describes how to give WorldPainter more memory, in case it is giving error messages saying that it does not have enough memory to complete an operation.
