Hi Guys,

Quick question about Octane texture I try to do it a kind of hardware hatching shader I manage to get really cool results but I was looking at a paper http://www.cs.utah.edu/~emilp/papers/praun01rth.pdf or http://www.cs.utah.edu/~emilp/research.html and I was think if is a way to achieve this , Basically my version I use octane Falloff Texture but I would like get a value from the light shape so I could map the different texture about the light I manage to get something from a Matcap normal and project as a mask but doesn't work as a shape...

Please any advise????

best

here some test from Octane I use a cube projection and falloff texture for mask plus dirt textures.

Quick test with Octane what I'm tried to do it was a kind of hardware hatching render.

I'm try to achieve this effect,I still need find how to use a light value for texture so the effect
will be drived by the light source, from now is only a facing ration effect.
I use Direct Light Kernel and full hd 7 seconds (just to upload could be reduce to 4 sec)

If anyone have a idea how to get a light value without UV requirement.
For all this I don't use UVS.

here a video and High resolution:

I'm doing this already if see my comment I use falloff texture to blend different values but this are based at facing ratio of the camera quite a blue channel on a point world.(mesh)

This Technics I'm use already to achieve some results...

I'm also very interested - I hope you will succeed and you lay out a lesson
