    Volumetric Fog / ExponentialHeightFog - Ray Tracing Translucency Problem

    Hello,

    I am pretty new to Unreal and I have been having issues with volumetric fog and translucency materials with ray tracing enabled.
    Essentially, I have a scene with a ExponentialHeightFog and an object with a translucent material. The issue is that when I enable Ray Tracing on my translucency type - the material renders over the fog instead of under it. But when I change the translucency type back to Raster the issues disappears.

    Is this a limitation of Unreal or am I missing a step.

    I'd be grateful for any help.

    Thank you!

      Try changing Translucency Sort Priority (higher renders on top). There's also Render After DOF, and Separate Translucency, but I'm not sure if those would work to enable / disable.

      The only other potential fix I can think of is changing the material blend mode to Additive or Modulated. It probably requires changing the material graph though.

            Volumetric fog is not supported with raytracing.
