Specular on full

[tjheldna]

It's appearing that with the dynamic - diffuse_normal_specular.shader the specular is always on full blast no matter what you change in the spec fields in the material editor.

 

Cheers!

yes , i also just experienced that importing a 3D model ( what a big regression )

[shadmar]

That is a bug, on line 87, comment in :

 

 //lighting_specular *= color_specular;

[shadmar]

If the intension is a specular map, this would have to be added aswell :

 

After

uniform sampler2D texture1;//light map

 

Add

 

uniform sampler2D texture2;//spec map

 

Find

 

vec4 color_specular = materialcolorspecular;

 

Replace it using :

 

vec4 color_specular = materialcolorspecular*texture2D(texture2,ex_texcoords0);

It don't correct the problem, tested it and LE3 don't uses the specular map with these modifications.

[shadmar]

*sigh*..

Im' not shader or even less programmer.

But this sort of shader must be standard and found on google easy , no ?

I used also some old 3D engine, having that normal map specular maps, they stored specular on alpha map (because this shader didn't used alpha for color and normal map)

So no news , on how will be some real specular shader using a bitmap specular image ?

[shadmar]

Did you even try the changes I suiggested in #3 and #4, works fine if I do it.

[YouGroove]

Indeed i tried nad tested and i said it changed nothing.

If it works for you , it means i done something wrong somewhere ?

I'll reconfirm and retry tonight, i'll post shader and texture if needed also.

[tjheldna]

It worked for me, have you added a specular map and played around with the specular values in the material editor? (after you added shadmar's fixes)

[YouGroove]

Cool.

What to do with color_specular

As it is used nowhere ? (that's why i got full specular)

Muts i decomment, tested several times and tried other ways , it don't works ?

 

lighting_specular and replace some value ?

 

Can someone post here the full shader ? i mean dynamic lightening with normal map and specular map.

This was just a simple shader fix, and it has been uploaded.
