Did you make a search with 'edgeblend' ?

Split off the key and use a gaussian blur shader on it?

Thanks Stephan,

I found this: http://paulbourke.net/texture_colour/edgeblend/
it's very interesting learning.

But i need tutorial, i think i must begin the basics in Max, after that i return her to master class

here's how to do edgeblending with jit.gl.slab...

But it does not offer a solution to apply gamma correction on the edgeblend itself.

Hello Slimus.
This edgeb-blending isonly half way to the place I want to take it. I posted this example:https://cycling74.com/forums/edgeblend-between-projectors/

But no replies

I guess the shader posted by FP is still one oft the most comfortable ways to use edgeblending within Jitter? I never used it before, but i guess i shall split my final texture (5760x1080 or 5120x720) onto 3/4 cornerpins and use above posted shader before them. For the splitting is there a recommendation what might be efficient, the resample shader or are there more efficient options (f.e. rect + adapt 0 with jit.gl.pix)? Did Anybody ever try http://www.fly.elise-ng.net/immersivedisplaylite2 or similiar affordable software for Windows to do the edgeblending outside of Jitter?

thanks for any tips
