// Unity 6 TMP changed some things; adapt the shader for U6. Plus allow scale of transform to affect it.

Shader "TextMeshPro/Distance Field-BillboardFacing" {
    // Billboarding version for TextMeshPro (tested in 2018.3), based on default Distance Field shader. 
    // ** Important part is to DISABLE the dynamic batching! (happens in this shader) **
    // ...Took a while to figure out that one.
    //
    // Use as you like!
