Thanks everyone! All your responses made perfect sense. Gil, I assumed that you wouldn't need to know that for the import since you know the model you're going to

but I was curious why it was asking but Phrog30 explained why and now it makes sense.
Regarding the image resizing, here are the 4 options:
- Exact Height
- Exact Width
- Either Height or Width
- All
I've only used all and the either option and All got me the result I wanted which was a resized image which didn't look bad at all, but I'm sure it could if the tree was way out of scale with the original, but mine isn't really that much when you think about it...it's taller but only slightly wider. Plus the SS sequences made for CCR's are 3 lights per pixel so 50 pixels is 150 lights and I'm doing 200.
One thing I did just realize though is that the 6 channel star effects don't get imported from the .SUP file. Is anyone doing anything special to get those, if they need them, or am I just gonna have to pull them over in a data later from an LMS file? Not a big deal, I can do that, but I didn't know if there was a trick I was missing.
