Has the GeNa river material changed?


Recommended Posts


After days of painstakingly chiseling the terrain I managed to get a waterfall working from a GeNa spline. The surface looked like a rough river and I was happy with it. After updating the assets in my project the surface now appears as Foam.

It may be that it's intentional 'white water', but the problem is at the base of the waterfall where there is no direct light, that foam looks more like a static white strip.

Has the material or shader been changed? Is this appearance something I can control manually? I tweaked the values on the shader of the mesh and wasn't able to make it less foamy/white and I couldn't see any obvious alternative shader or material to use.

The meshes are using "Shader Graphs/PW_RiverFlow_LitBasic_HDRP", for HDRP in 2021.3.5f1

I've discovered I can make the foam less visible if I adjust these two values:


However, the 'rough water' then starts part way down the wall, with the actual bend being transparent. Also the water texture is moving at an angle (not intentionally - I don't know how to fix it). It means if the rough water doesn't start at the bend it looks angular with a triangle of clear water
