While updating this billboard shader https:\/\/github.com\/unitycoder\/DoomStyleBillboardTest<\/a> , had couple strange shader issues:<\/p>\n

Problem#1:
\nOverlapping transparent area clips other object behind it<\/strong> (see issue#6<\/a>)<\/p>\n

This one was solved by adding “ZWrite Off” to the shader, apparently something to do how transparent objects get depth sorted..(?)

—<\/p>\n

Problem#2:
\nIf there are multiple copies of the same object, rotation\/scale\/direction is broken, object moves to wrong direction as if they are locked together<\/strong> (see issue#5<\/a>)<\/p>\n

This one was solved by adding DisableBatching”=”True” to the shader tags. So Dynamic Batching was the issue..<\/p>\n

Tags {“Queue”=”Transparent” “IgnoreProjector”=”True” “RenderType”=”Transparent” “DisableBatching”=”True”<\/strong>}<\/p>\n

Other option was to disable [ ] Dynamic Batching from player settings.. but that would disable it for all objects..
