Earth, Materials Specular and Bumpmapping

[ikam]

HI

I was playing with materials and the different mod texture and mapping, and I fail to do what I want.

It's the earth, I want to add a normalmap to sea and earth (same or different), but apply a specular only on the sea.

if someone knows how to or succeeded

Here the project, it's a good training for texture mapping.

Ok I found how to do

Trick is to add texture over phongs and a new menu appear (it's magic) you can now play with Transparancy and rgba transparancy channel

hä?

what should this be... 2 times phong as shader? texsur on phong ? ???? you just use the mod shaders one time... never seen ONE mat with 2 shadertypes (phong+phong) the displace tex is not ness. single Flat surr. tex is senceless.. suround flat tex?? dont need aux for this.. at all less is more.
if you add tex on phong the "phong by tex" menu apPpears.
you need ONE shadertype 2 DIF and ONE norm map and maybe ONE modtex type (additional) to create this do not think to complex using the mat op. more eyes on the texture itself the AUX most makes sence with terrain stuff like the rove stuff, or our frozen.

hi, guys.
here is my attempt at earth. the file uses the same base textures as in the .zip file above.
to see the result just change the paths in the import ops to yours.

p.s. by the way, is there any way to make wz4 use relative paths?

[ikam]

reEto : Ok I will try an easier way as you said...

Skinnytorus : you can setup a project path in document option (edit menu), all files you will import will be relative to. And thanks for your adds, nice.

[Skinnytorus]

Thanks, but it's not exactly what I meant.
Say, I have downloaded a zip file with .wz4 file and textures.
Can I make wz4 load textures using location of wz4 file as a base without changing project path in Document Options and/or in Import ops?
It would be much easier to handle downloaded projects this way...

Ok here I remove the second phong and it's works like I wanted. But I don't see how to assign differents normalmap to sea and ground without "Aux" op...

(I replace earth textures with a perlin to avoid imports reload).

[Skinnytorus]

In fact you can pre-mix the Normals, but you'll lose in quality.
Take a look at the example.

[Skinnytorus]

I fiddled with ops a bit more and... tada!!!
Different normal maps with no Aux and no loss in quality!

Nice, well done.
Thanks
