When I record an keyframe animation video from microstation v8i I face an issue like there are some patches visible in the video. The following images are for your reference.

For your information, I have kept display style as :"SMOOTH - SKYSPHERE" and I have kept the default lighting "ON". I am using the following settings for recording the keyframe animation. Can anybody suggest me how many hide to light patches

can anybody suggest me some good settings for video clarity.
