sharpen and blur shader

I would like to have a sharpen and blur shader. There are many reasons why you would want to blur or sharpen a texture map. (artistic reasons, more or less micro details etc.)

Right now, you need to load the texture in PS, change the texture to your liking, export it, reload it into C4D, start IR and repeat this user unfriendly process until you are happy. This would be so much easier and faster if you could do basic operations like sharpen and blur inside C4D. It would be even better, if it would work not only with textures, but also with procedural shaders like the noise shader.

Substance Painter has this option and I often use it, when I'm texturing there. Hope, this will also come to Corona.

Thank you for considering this idea!
