Question by simonwrede · Apr 29, 2016 at 10:17 AM · shadernormalmap

Normalmap not applied until expanding shader in inspector?

Title describes it well, but I'm applying a normalmap via a script (at runtime). The normalmap itself doesn't get applied until I expand the shader.

Demonstration

The colormap/diffused gets applied the same way and works fine, help me solve this :).

You must enable the Standard Shader variant by using the EnableKeyword function. A different variant would be required if you start using a shader feature that was not initially in use by the material.

The specific Keywords required to enable the Standard Shader features are as follows:

 _NORMALMAP (Normal Mapping)
 _ALPHATEST_ON (“Cut out” Transparency Rendering Mode)
 _ALPHABLEND_ON (“Fade” Transparency Rendering Mode)
 _ALPHAPREMULTIPLY_ON (“Transparent” Transparency Rendering Mode)
 _EMISSION (Emission Colour or Emission Mapping)
 _PARALLAXMAP (Height Mapping)
 _DETAIL_MULX2 (Secondary “Detail” Maps (Albedo & Normal Map)
 _METALLICGLOSSMAP (Metallic/Smoothness Mapping in Metallic Workflow)
 _SPECCGLOSSMAP (Specular/Smoothness Mapping in Specular Workflow)
