I am taking some renders from rhino 7 and having some strange shadows appear when moving the camera around. They are quite large and not form anything in the model and only viewable from certian angles and zoom lengths.
Welcome to our Forum.
I reckon you may have a AMD graphics card built into your machine? If so, then this could very well be the following known issue which was discussed here.
The solution for the time being is downgrading your AMD drivers to version 22.5.1. You can acquire them through the official AMD homepage. If you need any further assistance or in case this does not resolve your issue let me know.
