After the upgrade to 2021, realistic Rendering doesn’t work at all for my current project. When the render is done it warps whatever is seen through the windows with the Glass texture and generates really really bad artifacts all over the render. I have to go back to Vectorworks 2020 until this is fixed.. Really dissatisfied with an upgrade that causes so much problems. Is this a common bug or is there a change in settings that can correct this? If it is a bug I don’t understand how you have missed such a big problem in quality control.
