I was having a frustrating time for a while with blender. Whenever I imported a model it would take a huge amount of storage and run slowly. If anyone has this problem, consider unchecking the Lego logo while importing. You lose a bit of realism, but get a huge reduction in memory and you can run blender so much faster. I don't know if anyone needs this advice, but it was very helpful for me so hopefully it can help someone. Also, am I supposed to put posts about blender here or somewhere else on Mecabricks? Thanks.
