Shader to render RenderTexture plus alpha?

Deepestblue · April 28, 2013, 12:09am

Hi all,

my MiniMap has a circular shape, the RenderTexture (naturally) doesn’t. I would like to get rid of the unneeded corners. Is a shader which will take the RenderTexture as unlit and add a greyscale texture as alpha channel? If so, has anybody a clue how this could be done? Or are there any better ways to achieve the same?

Thanks for the help!

Sorry, found it after asking.

Creating a Basic MiniMap in Unity 3D - Part1 - YouTube and Creating a Basic MiniMap in Unity 3D - Part 2 - YouTube even has a tutorial for that.
