Currently attempting to simulate the birth of a star within a gas cloud. The thickness and behavior of the smoke has been established, but I'm still getting a sort of "grain" to the cloud itself. Below are pictures of the cloud and a few of my settings. Could someone tell me where I'm going wrong, and where to fix the issue?

Thanks guys!
