Normal-as-color in pixel shader?

Unity Engine
1

There’s an example in the documentation on how to do this in the vertex shader, but I want to do it in the pixel shader (in the terrain shader).

Simply saying o.Albedo = a.Normal just gives me a black result.

hello, need to see more of your code…

are the a.Normal in WorldCoor or objectCoord ?
if you have to transform your normals to World in a vertex program.
like this :

void vert(inout appdata_full v, out Input o) {
	o.worldNormal= mul((float3x3)_Object2World, SCALED_NORMAL);
};

hope that helped.

This put me on the right track - thanks!
