Affect Distance Field Lighting and NOT cast DF shadow?

Anyone know if you can set a mesh with a masked material set to fully transparent (Opacity Mask = 0) to ‘Affect Distance Field Lighting’ and NOT cast DF shadows?

I’m using the Distance to Nearest Surface node to generate various material effects by using ‘invisible’ meshes to trigger it on other meshes.

can’t you just disable shadow casting on the invisible meshes? via static mesh details or the “shadow pass switch” node if you need material or effect specific control.

Thanks, but no - neither of those appear to impact DF shadow casting. It’s much more visible in low-light settings on the shadow-side of objects. My example here isn’t great, but you can see it near the end of the video.

Inisible cube has masked mat with 0 opacity mask and ‘Affect DF’ on. The visible cube has ‘Affect DF’ off.
