I’m doing a model for an apartment, around 80 sqm, and have prepared a model. The file size is around 1.00 GB, and crashes when initiating rendering. To circumvent this issue, I wanted to create versions of the same file, each one retaining only the room that is to be rendered, deleting everything else. However, deleting everything except what is in the scene for rendering didn’t affect/reduce the file size and still crashed when rendering. Copying the contents into another file worked both in terms of reducing file size and enabling rendering. I’ve tried purging, removing parts or Warehouse models I considered problematic etc. and nothing did the trick, until I just moved everything into another file. This hasn’t happened before, and my question is: what did I do wrong?
