Hey all, I have been building landscapes in EI for a feature I'm working on. One shot calls for a landscape soft-lit, as if by sunlight though medium to heavy clouds. I struck on the idea of making up an HDRI image and just using Global Illumination to light the scene, no lights at all. After a few practise runs to make sure my geometry was all looking okay, and dealing with a pesky anti-aliasing issue, I thought I had it done. The landscape does not move. The camera flies over the top of it. That is all. After a lengthy overnight render, I find there are areas that are buzzing or shimmering, as if I have noise turned up to 11. I have high polygon-count trees in the scene, and it looks like they're covered in ants. Add to that there's an odd strobing effect with shadows being cast, like a moire pattern. I haven't varied my skymap resolution yet (1000 x 500 pixels), that is my next thought, but other than that I'm wondering if there's some solution that's not going to result in a week-long render. Can I "bake" the scene with that light? Is there some simpler solution? David
