Hi people,
I’v been bussy exploring the max SDK and maxscript.
While doing i created some simple maxscript render effects 4 in total :
- Greyscale
- Contast
- Gamma
- sepia
These are simple render effects, and proberly useless. but well hahaha maybe some1 actualy would like to have them 
To use them just run them and you will find the effects in the rendering > effects dialog of 3dsmax
btw if some1 would like some other effects in there, just post them here. maybe i can get into it.
