Cross-Hatching Shader finished

I want to share the cross-hatch shader which is based on:
http://research.microsoft.com/en-us/um/people/hoppe/hatching.pdf

I have still some problems with it

1) on spheres, there is a clamp problem
2) I couldn't use DDS files because of erros (previous posts) (therefore, the quality suffers from it)
3) I would like to have done it as a subsurface shader, but i have no knowledge atm.

Wish you a nice day

 

Hello, I think you made it a bit wrong. As I understand this technique is used to replace standard lighting model, so you can write custom model. I rewrote your shader with some changes so here it is

Hey ufo_Driver,

thank you very much. now it looks correct like on the paper i was reading. I was on the way starting to read some surface shaders to implement it, very very nice! You made my day!


bye

 

I'm having difficulties in getting this to work (in Unity 4).

The lighting completely does not work and it simply renders the model with one of the textures.

Could anyone help me out, perhaps by uploading a demo scene of this shader?

 

I got ufo_driver's shader to work. Although confusingly I had to reverse the order of the hatching textures for the lighting to look correct. So Hatch 0 should use hatch_5.jpg, Hatch 1 should use hatch_4.jpg etc.

 

Thanks @xsernakatomi, @ufo_Driver and everyone working on this. It's working for me as for @Gibbonator, changing ther texture's order. Now I want to keep the base texture under the hatchings, but no success so far. Just beginning messing with shaders so if someone have some clue or direction, I will appreciate =)

Edit: Got this one working gratefully:

how did you manage to mantain the base texture?
