Here is a quick tip on how to speed up your renders. I will also show you, where to delete unused cache files that Blender creates. This way I could get sometimes 70 GB more space on my computer. :D
So check it out and I hope you like it!
This tutorial describes how to delete cache files on Windows only – who can tell us how to do this on other operating systems?
Just in case someone doesn’t know this already, you have to enable ‘hidden files and folders’ to see the ‘AppData’ folder. To do this, simply click ‘Organize’ in the upper left corner of windows explorer, and click on ‘Folder and search options’, Then go to the ‘View’ tab, and enable ‘Show hidden files, folders, and drives’ by clicking the circle beside it then clicking ‘Apply’.
On OSX you can check disk usage for Blender support files with this OSX Terminal command:
du -h ~/Library/Application Support/Blender/The final line of the output tells me, for example, Blender is using 6.5MB in total on my machine
Under Linux (Arch Linux in my case), BVH cache is in
~/.config/blender/2.73/cache/
Nice tip, I actually believed cache was deleted with the end of session like temp files !
