Flat shading

[ocean]

So, if I'm ever going to get a project done I'm going to have to go retro... Is it possible to make a super-low-poly flat shaded game in Leadwerks? I tried importing plain colors as textures, but they seem awfully smooth by default at least.

Recalculate normals to completely remove smoothing.

And I suppose you can import one 1x1 pixel white texture and change color for each material in material editor.

You don't even need textures, materials can just have a diffuse color.

 

It's probably easiest to just build your normals using the angular threshold method above, using a tolerance angle of zero. This will give you completely hard edges on any model.

Brilliant! Thanks!

But am I right in assuming this does not apply to brushes? EDIT: Or terrain for that matter?

[Josh]

Brushes are always hard-edge unless you have smooth groups. Cylinders, spheres, and other round shapes have smooth groups but that can be removed.

 

You will need to modify the terrain shader to make that have hard edges.

[Genebris]

Or use your own mesh instead of terrain. If you don't use textures and have low poly models this shouldn't be a problem for performance.

You can recalculate normals with a geometry shader as flat like this: (will override all mesh smoothing)

 

vec3 edge1 = vertex_position[1].xyz-vertex_position[0].xyz;
vec3 edge2 = vertex_position[2].xyz-vertex_position[0].xyz;
mat4 nm=transpose((cameramatrix));
vec3 faceNorm = mat3(nm) * normalize(cross(edge2,edge1));

make a terrain in blender:

make a heightmap in blender to import it into leadwerks terrain (does not have not what you want by default) :
