Hey, nice cross-hatch example varomix - thanks!

And welcome Farsheed - nice to see new people here.

In crosshatch-type shading, I've found the Shading Quality of the surface makes a huge difference to the look of the image. Don't forget to play with that:)

Thanks you all. I Learn a lot from you. I am starting to switch to Houdini.

Thanks all of you for your time and apologize for my Maya-ish stupidity.

I was actually playing with this idea last night

I did it kinda different , but I like this idea, nice, very nice tip Mr. old school

I did it like the simple ramp shader using a frontFace and a normalfalloff

and a ramp to control the bias

I came up with this in the process

and Farsheed, chill out man, we are all brothers here

I made you a scene with a couple of nodes based on Old School's scene, the rest of the nodes

he created there are the parameters for the shader, he was kind enough to make you

a full working shader

here's the uber simplified scene

_mix_fakeFresnel_v01.hip

and my crosshatch scene if anyone is interested on that

_mix_shaders_v01.hip

welcome to the magic of houdini man

I rendered the scene with ray-trace and the result was nice but you must set the shading rate to a very high number in micropolygon mode to get the same results.
