Having A Transparent Texture On An Other Texture

[chantren]

Hello everyone, here is my problem.

I need to apply a texture on a character's face. But that texture is actually separated into two texture. One which is uniform for the skin, and the other for the details etc... What I need to do is applying the second texture on the first one with some transparency depending on the angle between an orthographic camera and the model. So I am wondering if all that is possible ? I have tried some things so far but nothing good. I tried using ramShader with textures but the result was awful, more like a mix of the two textures than the first one with transparency.

I might not be very clear so ask if you don't understand something.

Thank you !

make a layered shader node and turn its mode to texture

you might also want to look at one of the xray shaders in the download section on how to use camera angle to control the mix

Thanks for your quick reply, i'll let you know if that helps me.

Ok, the layered shader node works fine but the texture is getting awful when applied with that method, is there any reason ? Moreover is there a way using layered shader to have transparency not equal all over the model ?

I also tested the XRay, which was useful but i noticed the same deterioration of the texture .

Thanks in advance.

deterioration? what res is the image? turn off the filter on the 2d texture node

Hi !

Sorry for the delay I was away for the week end.

Here are the sizes of the two textures :
- 358 * 358 for the uniform skin texture
- 300 * 450 for the face texture

I tried to turn off the filter for each texture node, both and none but that didn't change anything .

Ok the bad quality is not visible in render mode so that doesn't matter ! I will be able to get the result i want using xray shader, I'll ask if another problem shows.

Thank you!

Hi again, I am facing another problem...

I am using the xray shader (http://www.highend3d.com/maya/downloads/shaders/599.html) and it is almost what I was looking for. Indeed, when a render my scene with an orthographic camera I got the result I want. But when I do it with a perspective cam I don't. Is there any way to have xray effect only depending on the position of the orthographic camera, so when taking pictures from a perspective cam the effect has not changed.

Thank you.

Yes, do: direction dot normal, instead of asking for sampler info.

[chantren]

Hello,

I understand what you mean but I don't find anything like "direction" in the Hypershade, where can I find that ?

Thanks

Not in hyper shade you connect in any node that can pass a vector.

PS: if you use mr in 2009 then they have ctually screwed up teh sampler info node a bit it doent seem to update the matrix eye to world.

In any case you can just do this with a directional light instead same maths on lambert material!
