Oh that was it! Makes sense now that I think about it! Thank you. And btw great job with this plugin!
If I can drop a request here, it would be great to also be able to use the built-in BP_CloudMask_Object with these clouds, to have more artistic control over the sky. Not sure how complex that would be though!
