No phong shading for .ase models?

[Clueless Newbie]

I couldn't figure out why the phong shading wouldn't "take" on my boulder models, so I hacked up a brush for comparison. Here is the result:
The .ase model:

The brush: (no, it's not touching the ground)


It's pretty obvious which has phong and which does not. Is there a way to convince the light renderer that the models are supposed to have phong shading?

Oh, and here's a screenie of the map I'm working on:

The only really big "to do" left now is the skybox. And fixing all the bugs I'm bound to find real soon..

For models, you need to do the phong shading (also known as smoothing of the normals) in your modeling app.

Per-luxel lighting requires visibility data, it is not performed on models, only structural brushes.

That would be GTKRadiant. How do I do that? A full BSP, VIS, and LIGHT compile of the model?

modeling app = (in this context) where you created your .ase model.

SavageX: Are you saying that if smoothing is enabled in the modeling app, it will appear in-game? Or that we need to bake the shading into the texture with the modeling app?

Code: Select all

textures/where_your/rockshader_texture_is
{   
    q3map_nonplanar
    q3map_shadeangle 40

// Remove next two lines if you dont want the model to be solid.
    q3map_clipmodel 
    q3map_forcemeta

    {
        map $lightmap
        rgbGen identity
    }

    {
         map textures/where_your/rock_texture_is
        blendFunc filter
    }

}


Set q3map_shadeangle to the maximum angle you want smoothed. save as scripts/yourmapname.shader, add to scripts/shaderlist.txt

compile and enjoy

tbh i think the non smoothed rocks looks more rocky :O

The former, I guess. The modeling app has to write smooth normals, q3map2 apparently will only smooth normals for brush geometry.

I tried that, but it didn't work with the models. Maybe I did something wrong.

I set the phong to 120 just to make sure the difference was really obvious. I think maybe 90 would be a better value.

Did you try what SavageX said, with smoothnormals in the modeling app?
