 	* robert on plekiline, vunts õiget värvi :)
 * quest marker järjest järgmise tegevuse kohal: mikrofon, siis nupud
 * character billboard:
-	* tulnukale korraliku resolutsiooniga suu / silm liikuma
 	* klaas on näha temast eespool
-	* pööramine kaamera poole - sujuvalt (slerp)
 
 Can't/Won't Do:
 * glTF loading: vahetada ära shader Universal render pipelin Lit, mitte panna buildi kaasa glTf oma - **ei saa, objekt on siis ilma tekstuurita, lihtsalt hall**
