Hi there, I was wondering if anyone here knows how to setup the VRayEnvironmentFog with a shader that could control near/far properties? Ideally, getting the fog to start like 50m away from the camera to infinity would be perfect. I’m mucking around with the FalloffTex plugin texture but have had…

Do you need a gradual start of the fog? Best regards, Vlado

Hello Vlado, Well I think the VRayEnvironmentFog already has a gradual start to the fog, it works well in most instances…so I guess I’d be after something so that the fog suddenly starts at a designated distance. Obviously one could attach the fog to Mesh (using the Invisible Shader method), but t…

well as far as my knowledge goes u can make a bounding box from where u would like to have a fog and so on…

Thanks Bazuka, yes that is possible and I thought of it, but I’m thinking more of a “computer game” type fog, where it moves with the camera. I suppose one could parent the bounding box full of fog to the camera, but I thought that it would be easier to set it up with just a distance type shader an…

Is that the effect that you want to achieve? DistanceFog.zip (8.57 KB)
