Hi Ronald
I’m away from my machine but essentially it was 1600 square tiles in a square array that had a different photographic image UV projected on each side. A burning sphere moved in a spiral path above the array and, using animation nodes, they flipped over in its path. One camera followed a simple tracking path and there was one light source, no background at that stage. So, not a huge number of polygons (6 per tile and a UV sphere), recorded at 24fps and the resolution was 4k. I can’t remember the other render settings but they wouldn’t have been radical – i’m not at that stage yet!
As for the performance tips, they’re terrific. Will work my way through and see how it helps.
Very much appreciated, thanks.
