Hello, just got Vue4 today and started out straigt away trying to create a simple underwater image using a quadratic spotlight to fake the sun and create lightray's in the water. Now, after 20% rendering (Final) I saw black and white curves on the water surface. The never dissapered after anti-alaising. I am pretty new to Vue, starting with 3.1 before the summer. I would guess that it has to do with the texture bumpmap....and I would really like some feedback on how to correct this! (I upgraded to 4.02 straight away) I also included a picture of the problem! Thank-you in advance!
