I have a dynamic skylight which is sourcing an hdri texture (starter content map). 2 Using the “absolute world” position node in the material editor as input or part of the input causes the dynamic volumetric translucent shadows cast by a directional light from either a particle or mesh to cut away when in certain positions. I originally thought it was an issue with Lumen not handling translucency or masked materials well, but I get the same issue with Lumen (and lumen reflections) off. Multiple Scattering Extinction This gives a colored extinction value for objects that have a volumetric translucent shadow, such as smoke or steam. The problem I face is that I have to trade reflections for shadowing. You have plenty of options to customize the clouds and the lighting looks correct, especially in combination with the PBSky (the other cloud option “Cloud Layer” doesn’t, but that’s another story). This means being able to efficiently light small enclosed scenes with small lights to large worlds primarily lit by single dominant light source. SMRT. Light functions are also taken into account. question Volumetric Set the culling mask to only include objects which need to cast volumetric shadow (doesn't matter if the shadowmap mode is static, as then the shadowmap is only rendered at startup). 0 that had translucent shadows.
