Toolbag’s current system requirements remain the same for Toolbag 5. Since Toolbag is heavily GPU-dependent, for stability and performance, the more VRAM the better!
We strongly encourage users to run Toolbag on a machine with at least 16 GB of system memory (RAM), and 16 GB of video memory (VRAM). If working with UDIM projects in baking, texturing, or rendering, consider a machine with at least 32 GB of system memory.
During the Toolbag 5 install process, watch for the prompt to migrate any Toolbag 4 App Preferences, Workspaces, and Library files to Toolbag 5. Doing so will save you a lot of extra setup time.
