Picked up Truesky http://forum.unity3d.com/threads/truesky-for-unity.246880/ while its on offer. Having an issue running it with Sumino, the 2 don't play nice together. Once Truesky is turned on it causes suimono to stop rendering to the horizon, as can be seen in these pics. Only Truesky activated: It renders clouds to horizon, ana appears to render a grey cube border around the camera below the horizon. With Truesky and Suimono activated together: Suimono only appears to render if there is a geometry behind the water everything else appears to be culled. You can see the grey border of Truesky between the terrain/water and the horizon. Only Suimono activated: Water is once again render fully to horizon. Any ideas how I can get the water to be render fully to the horizon. Happens in both Forward and Deferred in all modes DX9, DX11. TrueSky appears to use a "camera.depthTextureMode" to render the clouds to the main camera.
