I'm pretty much running out of space in my project drives these days, and after some research it seems that most of the space is taken up by the many SP files I have saved over time. Some of them are ridiculously big, especially when compared to the Blender files they were imported from.
For example, one Blender file of a complete scene I have is around 100mb , but a few assets in that scene , imported into SP as and FBX file, textured and saved as a Substance Painter save file is pushing a massive 2.8GB! How?
So when you think that I have realistically 50 to 100 of these saves for various projects, each one being anywhere between 500mb and 5GB , then it doesn't take much to work out why I've filled up my SDD.
I read somewhere a while back that SP saves every file packed with EVERY texture asset you have installed in the software itself, and not just the ones you used in the actual project you save , and I have a LOT of materials and am always adding more. Am I doing something wrong? is there a way to save a SP file so it doesn't literally take ownership of my SDD?
Thanks in advance for any advice.
Substance Painter files are giant because they store a ridiculous amount of info, such as all of your brush strokes. This is probably excessive in many cases, but it does allow you to do cool things like paint in 2k but export in 4k at full quality, or rearrange your UV's and re-import without losing any work. But at the very least I'd recommend deleting all the autosave files when you're done with a project since that will save you some space.
