Shade-C EVO uses deferred rendering so a water shader is not an easy job. water shader in general a hard job.

terrain shader could not be a big problem. oliver2s made a good one for his project, but he had to switch to unity. Boh_Havoc also left gamestudio, more exactly switched to unity. I thought I will switch to EVO from the old Shape-C package what I customized in MapBuilder (simplified/improved), but after some testing of EVO finally I switched to UE4.

I do not know anybody else who is dealing with the development of Shade-C...
