Question How do I use global keywords

I have created the global keyword RENDER_ONLY_COLOR using GlobalKeyword.Create.
I am enabling it using Shader.EnableKeyword method.
In shader I have:
#pragma shader_feature RENDER_ONLY_COLOR
and later in code I use like this:

Code (CSharp):

1. if (RENDER_ONLY_COLOR)
2.         col1 = pixelColor;

but I get an error:
Shader error in 'test/ColorShader': undeclared identifier 'RENDER_ONLY_COLOR' at ... (on d3d11)

what I am doing wrong?
EDIT:
Ok, I have found what I was doing wrong, but It behaves as if it was always true. When I disable the keyword it disappears from the list of enabled global keywords but the shader still behaves like it was enabled.

 

#if defined(RENDER_ONLY_COLOR)

or

#ifdef RENDER_ONLY_COLOR

Code (csharp):

1. #if defined(RENDER_ONLY_COLOR)
2. col1 = pixelColor;
3. #endif

if

is a branch in the shader code itself. Keywords are preprocess defines, and preprocessor related code uses the

#

as a prefix, so you want to use

#if

.
