Sorry, I'm not able to visualize the "3 inner stars plus 5 tips" that you are trying to do. Perhaps if you took a picture or drew it out and posted it here that would help. Also, you can create a custom model that allows you to create any shape or design you want. However, I don't believe the custom model will let you create individual strands. What you could do though is create the custom model exactly how you want it to look and then create individual strands with the same channel numbers and deselect "In My Display" for those individual strands. By doing this you won't have to worry about placing those individual strands inside of your layout. They'll just be hanging out in the background. When you then go into the sequencing they will be available for you to use individually. Since you set them up with the same channel numbers they'll light up the corresponding parts of your star. You may not even need to do all of that though. Post a pic or a drawing if you can of what your star looks like and then we'll have a better idea of what can be done.
