Extension methods enable you to “add” methods to existing types without creating a new derived type, recompiling, or otherwise modifying the original type. Extension methods are static methods, but they’re called as if they were instance methods on the extended type. see the official website. Let’s see one simple example:… Continue Reading C# – First steps with C# and .NET – part 047.

The Unity 2018.1 comes with two scriptable render pipelines known as SRP templates the HDRP and the lightweight render pipeline. The idea is to provide optimized real-time performance. In Unity 2019.3 the lightweight render pipeline was renamed to Universal render pipeline. All render pipelines can be install from the Package… Continue Reading Unity 3D – Set render pipeline and fix the pink shader material.
