Need hint with shading models :)

(system) #1

Hi Partypeople :banana:
i need help with my model. I made this cliffy wall for testing some model-with terrain stuff and my model turned out edgy.

Can someone explain how this -shade stuff works and post a working shader for a lightmapped model (my second wish :wink: )?
I tried -shade already but i must have missed some important details.
What is the best setting for shadeanlge? have it something to do with the degrees my of my sunlight?

Some tips or a link to a shading documentation would be very nice. :slight_smile:

My understanding is shadeangle applies to the angles between adjacent surface segments.

In otherwords, if the angle between triangle x and triangle y is less than shadeangle, then the lightmap will be blended across the two surfaces, making them appear more round.

So in order to get a cube phong shaded the shadangle for the texture used on this cube would have to be 91… or 271 I can’t remember which. Anyone want to settle this question for me?

Hi Fiesling,

In my experience, models must be smoothed in the 3D app they are
created in.
Use .ase for best results :slight_smile:

q3map_forceMeta
q3map_nonplanar
q3map_shadeAngle 120

Put above lines in the model’s shader.

I put some more polies into my model and modified the shader.
Now it looks better but not perfect.
And compile-time rised a lot with -shade switch on.
But i will tweak the lighting a little bit before i do a final compile. Thx for help. :slight_smile:

Try tweaking the shadeangle too… give it higher values like 180 and see if it looks more appealing.
