I know that the engineer working on the fluid rendering had started on it, then was sidetracked on projects for GDC and for customer support, so he was delayed a few weeks. I expect we’ll see something by the end of month. The GL shaders from the demo have to be ported to Epic’s RHI system, which I think uses DX-like HLSL. I’m not a rendering expert either, although I’m trying to come up to speed on it. Shouldn’t be a huge deal once he gets back on it.
