I have a problem with V-Ray HDRI in ground projection mode, placed inside a dome light: Changing the radius parameter has no effect on the parts above the horizon line. It only has an effect on the ground surface.
Please take a look at the three images. Don't laugh at the teapot, it is real-world car size, as indicated by the wheels. The goal is to show a car parked next to a sidewalk in a city. There is an infinite V-Ray Plane below the car, set to shadow catcher via the button in the V-Ray toolbar. The HDRI in the domelight is instanced to the background slot in the Environment Tab from Max.
By default, the part below is projected way too big, as shown by the big patch of asphalt below the car. Also, the window front behind the car is way too big. So far, so good.
Now, let's change the radius parameter for the ground reflection. The ground below the car is actually looking very good judging by the street and asphalt, but everything above the horizon line is not scaled accordingly. The background above the horizon is still twice as big as it should be. I can't understand the reason for this, as it brings up a number of problems. First, the reflections in the car would be wrong, and second there is a severe distortion from the ground towards the background. Because it has to blend from the correctly scaled ground to the incorrectly scaled background.
Here is a screenshot of the HDRI for better understanding:
Is there a way this can be fixed? Is it a bug at all? Basically I want to tell V-Ray how "big" the environment from a HDRI is that I put in the scene. If you need the scene, please tell me.
