Can this be done in Blender? I tried subdivide plane and use python. But subdivision as excepted don't go well. Then I tried material volumes, but can't get desired resolution and can't see how program volume except osl. Then I tried, using subdivision modifier with displacement modifier and script on texture image, but images in blender are stores as (r, b, g, a) when I only need one and it takes much memory and processing time.

  • $\begingroup$ @RobinBetts I don't want to disappoint you, but the only one thing I did with back feeding was Reaction Diffusion i never worked with sand in that way of your magic (•‿•) what is wrong with your solution ? It seems to match OP. $\endgroup$

  • $\begingroup$ @vklidu Thanks! You could use your RD method (compositor only) on the dunes, too, and get shot of the camera.. which does save a fair amout of faff. :) $\endgroup$

    $\begingroup$ I've tried to put together a kit, with relative file-paths, here. After extraction, before doing anything else, 'Render Animation'. That should populate the 'Render' folder with 25 demo frames and make everything else work. I hope :) $\endgroup$
