I am having an issue with the HDR images in the Light Dome. When rendered the image behind the model looks to be very, very blurred - where there should be clouds there is just a color which appears to be a blend of the colors in the light dome. See images below.
Everything else works, the model reacts to the light dome and the color behind the model changes if I rotate the dome, but there are no details in what should be the sky. See image below, there should be clouds behind the airship.
Also the preview window in the asset editor sometimes does not show the HDR and remains black.
I have a suggestion that has helped me GREATLY during trouble-shooting. I call it the render buddy. Yup, its a dumb name, but it actually works great.
Make a sphere and position it where the camera can see the whole thing without blocking too much of the scene.
Apply a shiny / polished chrome / mirror material to the sphere.
Render your scene.
The sphere’s reflection will show you the entire scene > above , below and behind the camera. You’ll be able to spot problems pretty quickly. For example, it will tell you if the environment map is loaded or not … and you might see some other lights you forgot about.
I use it often for interiors if I want to show the current setup of the whole scene and I don’t want to render every detail image by image. Best you set the camera at the middle of the room and horizontal aligned, the view menu “Set Camera -> CPlane Right” or something like this helps to do it too.
