Hi Frank, Try using a surface properties shader with illumination=texture(map coords).
chris mungenast From: Frank Bueters <[EMAIL PROTECTED]> The dome is shadow invisible and recieves no shadows. The material contains a hdri texture in a surface illumination shader (illumination=texture(map coords)). I have tried several other ways too, like a surface properties shader, a curve object to control brightness and much more, all to no avail.
