I got the look I wanted with the vector displacement map but when I tried to render it at high res I ran out of RAM. I am finding Corona very hungry on RAM when rendering at high res even without the vector displacement map. My image is 12,000 x 9,000px and I have to render my image in smaller regions and stitch together, which is no problem but now I am trying to render a small region of the above size and with the vector displacement map, it just can't do it - it sits on "Calculating displacement" for hours. My RAM is 24GB which I thought would be enough. Any advice? Thanks Theo
