Scaling textures for/with shaders.

Hi everyone,

I've done some shaders these days and right now i'd like to improve my blurring techniques... in order to create a bloom shader, I need a huge kernel (and a bunch of pixel weights) to get a satisfying result; but it's too expansive. Moreover, i'd like to reduce the number of instructions i use for my gaussian blur shader and get a better result (right now 7 samples). To do so, i need to scale down my textures, backgrounds or so. Is there a way to do that in hlsl please ? In construct ?

Thanks in advance.

By the way, should I release my effects to the community ? I'm creating a bunch of shaders that can be use with construct's events for cinematics (desaturate, blur with controllable range, color shift depending on world position, and all that kind of stuff).

...blur with controllable range...

You'd make a bunch of people happy if you released that one. People have been wanting that for quite a while.

Ok, i'll give it right away.

EDIT : done. That's strange that nobody already did this. You only need a float value from construct, which is explained in the wiki.
