I don't know why when I use sprite (from WED) in level and I have flags setting to flare and I use Player Biped wdl for player, after running level sprite is as billborad and is't faced to screen?

The "Flare" flag does in no way influence the orientation of a sprite. You have to use the "facing" flag.

Hmm. Yes. So it work, but setting this as action for sprite isn't user friendly. Thx.
