Looks like I have 7 separate images in my panorama. And the stains weren’t their when I used the materials.
There are no lights present, no emmissive materials. Everything but the mirrors are rough (no reflection).
What am I doing wrong ?
Not enough light in the area where the camera is pointing when it first starts rendering the panorama; the ‘stains’ are just a bi-product of the way it tries to compensate for low light levels.
Try increasing the ambient lighting and/or the exposure. If that fails, try adding in a low level light at the point it starts rendering.
Okay, got it. Figured it out it had not enough light. Have to practive a little more with it. Thanx !
Hm thanks for the workaround @Gadget_1 , but this should actually not happen. Looks like a bug. We will investigate, thank you.
