Question by DavidUken · Mar 17, 2018 at 04:41 AM · shaderuiuv2

Why doesn't UIVertex.uv2 work?

I was happy to see unity 2017 has a uv2 and uv3 channel, both in the canvas channel settings and in the UIVertex class, but these don't seem to actually work. They always seem to have zero values in the shader. Are they just a big tease or am I missing some way to make these channels work with ui shaders?

The second UV set in a UIVertex is actually uv1, not uv2. The first set is uv0. Are you trying to work with the third UV set (which is called uv2) by mistake?
