I’ve added a sidebar link to Flaming Pear, maker of Photoshop plugins, on this blog.
Many science-fiction artists will remember using their LunarCell (moons and planets renderer) and Glitterato (star-field and nebula generator) plugins in Photoshop, and some may still do so. These plugins still work fine for making backdrops elements in landscapes, and I see that Flaming Pear have updated their Flood plugin to Flood 2 in 64-bit. The interface is still a bit old-school, especially the clunky preset loading/saving, but the scene-reflective water it makes is very good and highly adjustable. It could save days of render time on 3D reflective water for large landscapes. “Now with improved 3D realism”, in Flood 2 — which seems to have been released late 2017?
Regrettably, when the picture has objects in the water at different distances from the camera, one has to make about for or five Flood 2 renders at different horizon heights. Then one layers these in and blends them together with the aid of a mask. It takes a bit of work and finessing, compared to just dropping in water onto a picture with a straight horizon.
