Quote - In this case you can render it without the bump maps. Go to the material editor, right click on the scene line and select remove bump maps. You will see that 600 something bump maps (actually references) are removed. Now the image statistics say you only use 10 grayscale maps and you can render it

Thanks to this tip I was able to load the scene though with scenes this big I cannot rotate the camera while Octane renders, I need to pause the renderer, rotate the camera in Poser viewport and hit the play button to resume/update the render.
