Anyone any ideas as to why I am getting the effect in the screenshot? I get it whether I use Flight Environment Clouds, or the AS Graphics - though only in some flights. I get odd clouds, whiter than the rest and moving faster. They appear suddenly in mid-distance to close up and even though they are clearly meant to appear to be closer to the aircraft than the other clouds, they always move behind other clouds, even ones on the horizon. The effect is very weird - it would be appreciated if anyone can help clear this up.My ini settings as below.

Hi, It's a thermal scenery that''s genereta these clouds, you must remove these scenery.ThanksChris Willishttp://www.hifisim.comhttp://sales.hifisim.com/pub-download/asv6...development.jpg

I realise now that you post this answer that I was only getting the odd clouds when I fly in India (one of my favourite FS flying areas) and that I installed thermals for India last month. I'll get rid of that scenery now and hopefully the problem will end.Many thanks for the reply - I'm glad there's such an easy fix!!Martin
