texture/effects help

Post by spy46 » 24 Feb 2014, 12:24

im working on a heavy space fighter of my own design, i have the general texture layout more or less done but when i render it, its still rather lacking.

the ship doesn't give off that metallic feel but more of a wall inside a house.

what can i do to make the ship actually feel like its made of metal, what are my options?

Add some enviroment .exr .hdr space enviroment map for example nebulas and stars to get some reflections apart from the the self reflection.

If you are not happy with phong and the classic shader nodes go for mia material and :


add some dark diffuse map,, and a small diffuse weight to get some responce to lights, and some small diffuse roughness
refl is metal on
bdrf freshnel on
add some anisotropy for example 10 and some small rotation to it if u like .

Important step is to add some bump map in the render tree this will spread relfections and specular reflections all over the place, and also it will justify the existance of anisotropy.

Play around with values like reflectivity, rfl ior , hl vs rfl balance , add relf falloff if u like etc,, there are alot of options

In general terms mia_material can give you better metals , im not an expert i just tryed to give u some starting point.

i know the texture itself would be just as important too, but what was recommended will help to create effects like this? whats the less complicated way to do this?

:-\ Hmm no. You will not get anything like that, i was thinking about xtra reflective metals like silver and fresh iron
Only this pic has some tiny glossy reflection all over it:

A very simple solution to achieve that almost lambert with a touch of smooth light reflections feeling is this:

A phong with low specular value(darker color like 0.3 or less) very spreaded (specular decay 8 or less)
enable reflections and add some low value like ~0.15, add glossyness 0.1 or more ,,2 samples or more.

Try this for start *-:)

Then add some enviroment map, and or some oblject to reflect.You can add env map in render render>pass options>add eviroment, (download some env .exr .hdr to play).Later u can create your color map and some bump map maybe.
