I think the problem is specific to tgdcli. I rendered 20 frames from tgd.exe and then switched to tgdcli.exe so I could play a game while waiting
All of the frames from tgd.exe were ok, but all of the frames from tgdcli.exe showed variation from each other. It looks like the code for reading the seed value didn't make it across to the CLI(?). If this is the case is there any chance of a minor update to fix this soon'ish?
I was also starting a cloud animation test (since I was rendering an animation) and got to thinking that if we had access to the wave fractal to displace it, it should be possible to add some animation effects to water. e.g. surface variation via translating fractal in y direction, + lateral motion by translating along x,z
