Next phase. This will be the view, and a first problem has arisen. The total render size will be 32400x7200px, which I hoped to do as one. Maybe by two large crops if necessary. But even a very small crop takes 15.8 gig of memory, and I only have 16Gb.
Without GISD that works okay, be it that detail and AA were low (0.4 and 4), hardly any objects yet, and no fancy stuff like soft reflection and soft shadows (that won't take more memory I guess, just takes longer). Higher detail and AA won't take more memory either I guess, just time.
But TG hangs if I use GISD, after having rendered the crop and whilst calculating GISD. Can't stop him either, nothing happens, not in a few hours. See screenshot.
So, is this memory related? Or size of the total render? Why is the memory use so high, what is being remembered, size?
Another option would be to divide the render size in two parts, but then it's hard (for me at least, last time Ben was my hero) to calculate the sizes, camera angles, and such. This view is looking down at 3.5º, so that makes it just a bit harder than a straight view.
Any advice would be greatly appreciated!
