This tgd file is Blend Displacement at Zero, shared file. Ulmus americana tgo tree. Wheat 03 tgo. Thank you all for sharing.
I used a two layer cloud system. One layer is set depth 10000, altitude 4000, coverage 0.4, density 0.002 and color light golden yellow. Second layer depth 4000, altitude 3000, coverage 0.2, density 0.003, and same color as layer one.
WIP but only 60 minute render at 0.6 quality and 6 AA. Cloud and atmosphere at 75%. Working on object scale and placement. Tricky.
