jade texture / material how to
polycounter lvl 14
Hello , I am wondering how to make a jade texture material ingame , is there any tutorial or do you have any tips to achieve something like this ingame ?

I have no idea on how to make the SSS to give a good look or how much shine I shoudl place on the object ...

It varies a bit in appearance though really.
As for how to go about creating it. Look up a lot of refs til you find what you're after. Grab a marble texture off of CGtextures or something like it that represents the material well. Change the colour and contrast until it looks about right, then toss some specular and gloss on there.
If you want a rough surface, then add some noisy bump etc. should be quite straightforward!
what do you think?
what you think hopw can I improve ?
Also try raising the "gloss" or "specular exponent" to a higher value.
I wouldn't try throwing on additional effects until you've got the specularity looking closer to what you want.
( Alternatively, can you edit the text of the pixel shader? )
You really need some way to adjust glossiness and specular color. It could be a slider, or a texture, or a variable in a text file.
for the specular lightning its based on the alpha channel in the nromal map
the darker , no spec , the lighter max spec
I try now to change some and see what happens ...
Your specular exponent (also called "gloss") is not related to the normal map's alpha channel. It must be adjustable somewhere else.
Googling "skyrim gloss" leads me to people talking about "BSLightingShaderProperty."
See if you can figure out what "BSLightingShaderProperty" is, and how to adjust it.
Green diffuse + Green reflections = green highlights, which looks metallic.
Green diffuse + purple reflections = white highlights, which looks more like jade.
the BSLightingShaderProperty is the property that allows to select the severall textures to use ..
but indeed I found those two settings :
glossiness float 65.0000
specular color set to a green one
specular strenght 1.6 ...
you suggest to changee those?
I do not understand well the difference between glossiness and specular , isn't almoust the same?
Specular level controls the brightness of highlights on your object's surface.
Glossiness controls the size and shape of those highlights.
High glossiness will give you small, sharp highlights.
Low glossiness will give you large, duller highlights.
Adjusting specular level will make those highlights brigher or dimmer, but won't change the shape of them.
glossiness 100
spec strenght 2
glossiness 50
spec strenght 1.5
Turn off parallax, subsurface, and cubemap, and start with a solid white (or grey) specmap.
Then adjust the values in BSLightingShaderProperty until you are satisfied with the color and shape of your specular highlights.
Experiment with gloss values in the range from 80 - 200.
Experiment with specular colors in the range from magenta to white.
Then try adjusting the specmap to account for grooves in the jade being more dingy while protruding parts are more polished. Your current specmap is probably fine, but I would still want to adjust one parameter at a time, to get a feel for what each value does.
Once you are happy with your specularity, then you might try experimenting with an env map.
here is with glossiness 10
spec strenght 2
about the env ma pseems that there are two maps one probably projected , the cubemap very small and the other seems a black and white mask so I guess is used for what gets taken by the env map ...
so if I want to make the metal reflect a lot I guess shoudl put more white there or same with the jade?
spec strenght 1
glossiness 25
spec color magenta pushed toward the white ....
as fprthe bronze behind I am splitting the two materials as I guess I can't use both the subsurface for metal and jade or the same env color ...
There's a lot of yellow in this image. Is it just from a yellow light source?
What does it look like with the specular color set to white?
You'll want to play around with the gloss level until you get small sharp highlights, like the ones on that Buddha. I'm thinking you'll want a much higher gloss.
Just fill the normal map alpha with solid white for now, since you want to see what gloss does on its own.
Once that's done, adjust the specular color and level until the highlights look white, like the ones on the buddha.
I would start with the grayscale texture at solid white, and adjust it gradually darker to see how it behaves. That buddha is pretty uniformly shiny, so a solid-color reflectivity is probably pretty close to what you want.
(update nif.xml if you don't see that in the shader flag dropdowns)
edit: wrong about own emit, not sure what that does. Opposing specular color does neutralize properly, even in a colored light, however.
I think for the diffuse it might be best to reduce, or even eliminate the dark areas and let the materials do the work.
for reference I looked at how they made the Ice to see the "parallax" texture and the subsurface texture , but I actually do not know how they work couse the parallax looks like a dark diffuse detailed color map and the suburface seems a very blurred inverted version of this with color as well ...
for the diffuse I wanted to give some contrast couse I want to shape to be recognized better as since is placed on a flat surface I would loose much of the carving detail otherwise I think ...
It is supposed to look like Jade ....
The thing to remember about jade, is that it's a very translucent material, and shadows are very light due to the subsurface light bounces.
I didn't yet tune the textures I removed the environment map tough and eft only parallax diffuse normal and subsurface ... I guess now is all about the tuning of the textures ? ...

There are many kinds of jade in different colors and transparency , I wanted to use an almoust gemstonelike type with high transparency ....
I wanted to gon the middle on this scale...

And FUCK YEAH, SKYRIM!
Edit: I wanna see the shield in use in the game :]
And yeah, it's definitely difficult to see what's going on in the sculpt. Material is definitely better.
