Hi,
I got strange artefacts when rendering the following setup:
An area light with a white plane in the back directed to
a “plane” (explanation follows) made from glass isn’t
transparent.
“Plane”: Add plane, enter edit mode, select all vertice, extrude region and lift the extrusion a little to get a gplass plate.
“Glass”: Material made from the default setting for “clear glass”.
Result: The glass plate is “filled” with a black “whirl”-like artefact.
I increased all “depths” I could found like “raydepth” and so on and played around with higher AA-settings: No success.
Since I have no webspace I am currently not able to provide an example…
If someone likes to provide me a little piece of mem (the blend-file isn’t that big…) I would be happy to post that file.
Thank you very much for any help or hint in advance !
Keep rendering!
