Hi Tirjasdyn, In regards to "Render settings: use displacement, raytrace and shadows on. It crashed on a 64 bucket and a 100 bucket. I have moved it to a 50 bucket and it was still rendering when I left this morning. Size is 2000 x 2041." If you are rendering with Separate Process (General Preferences > Render tab) turned on, I am confident that adjusting render settings can help. Please not that when you render in a separate process, the render engine cannot automatically reduce bucket size to counter a low memory situation. Therefore please start with a lower bucket size (8-16) and see if that eliminates the issue. Regards, -Brian
