I thought I was the only one who was having this problem. I’m having the same thing happing to me.

I've been working on a scene for a month now. The first time I saved the scene, closed out and came back to work on it some more, the program crashed. After about the third time this happened, I check the file size and saw it was huge. I just decided not to save what I was working on and render at the same time.
I haven’t quit out of the Bryce in a month. So now I’m rendering and that's taking forever. Pray I don't freeze.

I haven't started my garden because of this.

Me think it’s time to search the web for answers. I’ll let you know what I find.
