I'm trying to build a simple shader for a VR project using the Technic shown in this Unite talk: https://youtu.be/CYYPy6wXUQM?t=888.
I need a shader rendering a texture on the inner surface of a sphere, with a mask hiding some part of the texture.
To mask works fine but I cannot find a way to flip the normals of the basic Unity sphere.
I tried by simply taking a sphere in Blender and flipping the normals, working not great.
So I would prefer to use a unity sphere.
So, any idea how I could flip normals in Amplify ?
Thanks a lot for your time and help.
