Just been running a few tests on my mini trees with the mini stars on top.
For the trees decided that 100 pixel nodes per tree looked best.
The star pixels are connected to the tree pixels so that's 106 pixels per tree and therefore per output. The stars struggle with power when the trees are fully lit but I can get them glowing reasonable well if I reduce the brightness of the trees to 50% in certain parts of the sequence and at 50% they are still fairly bright
