Hello, it seems that fluid cannot be rendered when scene.useRightHandedSystem is set to true. Fluid just dispeared after the scene is switched to right hand system. I think the problem is that particle depth and fluid normal are not right.
I tried to fix the problem by inverting z axis in shaders, which does make fluid apear again. But I am not sure about rendering result is correct or not, because I do not fully understand the rendering algorithm.
Hope you guys could fix this bug, thanks a lot!
