On a megatree using the spiral effect with fade in - fade out, the very last pixel does not get the fade applied.

model: tree36
effect: fade_test
This is only a minor issue.
But when I went on line and created the fade_test effect, (as an example for you to look at), and I then the exported the vixen .vir file to my hard drive, the file was saved with a htm extension not with the vir extension.
