 ------------ Tyra's v2.0 roadmap to publish on GitHub ------------
 
 --- H4570
-- [Loaders] Think about ".tyrobj" format - implement it (add multicolor support)
+- [Loaders] ".tyrobj" format
 - [Loaders] DFF loader as static Mesh loader
 - [Game] Update intellisense from docker
 - [Texture] Test cache hits with large amount of textures (dolphin sample?)
 - [Demo] Create cool demo which will show all features of Tyra (I will take this one)
 
---- Wellinator
-- [General] Physics and stuff from threeJS
-
---- Unassigned
 
 - [General] Control generated id to avoid duplication. Maybe Just increment from 0? Add interface IIdentificable?
 
@@ -54,3 +50,4 @@ because Mesh rendering uses only core.render()
 - [3D] Add drawLine(x, y , color, size)
 - [3D] Add drawBBox(x, y , color, size)
 - [File] Async file loading
+- [tyrobj] Add multicolor support to tyrobj
