How come when I apply Toony - BasicOutline to a sphere the outline doesn't work when in an Orthographic?
Anyone know how to get it to work in an Orthographic?
Thanks.
It should work in both the Orthographic and Perspective cameras if you change the vertex program to something like:
v2f vert(appdata v) {
v2f o;
o.pos = v.vertex;
o.pos.xyz += v.normal.xyz *_Outline;
o.pos = mul(UNITY_MATRIX_MVP, o.pos);
o.color = _OutlineColor;
return o;
}
The problem with the old version is that the position was being adjusted in camera-space and The projected normals don't behave the same in orthographic projection as they do in perspective projection. The simple workaround used here is to add the outline in world-space and then project to camera space.
