That flag decreases light contribution from a light sources by increasing the extra distance:

    /* clamp the distance to prevent super hot spots */
    dist = sqrt( dist * dist + light->extraDist * light->extraDist );
    if ( dist < 16.0f ) {
        dist = 16.0f;
    }
    add = light->photons / ( dist * dist ) * angle;

I have used 3mb obj model referenced in map through misc_model, whilst trying to compile a bsp the memory allocations kept continuously raising over 4gb, till in crashed because it could not allocate any more.

-lowquality is supposed to enable low quality floodlighting, but currently it just disables floodlighting completely.

Also add a more meaningful alias: -lowqualityflood, -lqfloodlight?

Q3map2 ase model converter does material name wrong, it puts the 1st texture in a shader as material, so shaders won't work on models.

They lack one currently

Add basic, modern compiler presets that act as a good base for tweaking settings per-map basis

Compiler by default discards any surfaces in non-enclosed and entity-less map, making it impossible to generate ASE models. Should add flag to toggle this behavior.

The lightgrid directionality by default in some cases is really low, and easily drops down to 0 on a bigger light distances.

Allow saving which stages are included in compiler presets, to allow creation of just BSP or VIS test presets for example.

Organize switches to sub categories and add checkboxes to app to hide/show switches related to a subcategory (basic, advanced, debug, paths etc).

If different brush models have similar properties, for instance, they use the same texture(eg. trigger) and have similar size(up to 5 unit error?), they could be merged into s single model, to bypass the brush model in game limits.
-mergebrushmodels?

-srgblight doesn't work for example, need to type -sRGBlight

-blocksize n, -blocksize n n n
_blocksize defined in worldspawn takes precedence

-forceVertex a -cpma alias
-vertexOnly forces whole map to be lit by vertex only

_bounceColor allows setting R G B value for radiosity light, if q3map_lightImage is missing from shader, instead of falling back to qer_editorImage or averaging color from texture map. If a shader has q3map_lightImage, this key is ignored for that shader.

func_nonsolid, a compiler only entity that does nothing but set the brush nonsolid

-automapcoords automatically injects mapcoords-mins/maxs in the worldspawn of compiled bsp

Current ones are just copied from q3map2 wiki and contain some false information/not enough information.

-convert -format obj -absolutebitmap

With modern systems there's no need to worry about possibly having few extra bytes of lightmap data in favor of massive speed gains it brings to compilation.

Should add buttons to save the compile log into .txt file or to clipboard.

• Orientation of OBJ models is different from what's displayed in Radiant once map is compiled: https://streamable.com/qqfy06

• Material defined in the model is not compiled (usemtl material in the model file)

obj_test.zip

These define attenuation model when surfaces being lit.

Clean up unused/broken stuff and add help for missing switches.

Add switch to also include game_models in the conversion result if bsp is converted into model formats?
-convert -format obj -gamemodels

Allow setting different light attenuation calculations for different light sources, instead of restricting certain calculations to only specific types of lights.

refs #24 this is required for -vertexOnly

should rewrite whole thingy
