===== define ===== | |||
Injects a <tt>#define</tt> preprocessor directive into the shaders used in this pass. It is then possible to create logic around this define using conventional preprocessor directives like <tt>#ifdef</tt>, <tt>#endif</tt>, etc. Keep in mind that shaders must import the define before being able to use it. For example, for a define named <tt>USE_TEXTUREMAPPING</tt>, the following GLSL code must be placed right after the <tt>#version</tt> directive: | |||
<syntaxhighlight lang="glsl"> | |||
#pragma import_defines(USE_TEXTUREMAPPING) | |||
</syntaxhighlight> | |||
* name: Name of the define. | |||
* value: Value of the define (optional). | |||
