Black Mesa maps are too dark

[zEvilCube]

This is probably because the game itself is very dark, but is there a way to make maps brighter in this program?

Here's .cfg and .bat files I used

I can think of a few reasons why it might be so:

1. OpenSource doesn't support HDR lightmaps, it only supports the older format.
2. It doesn't support lightstyles (which are used for e.g. different lamps turned on) and will only read the first one.

I'm not in a capacity right now to implement any of the above. So I can offer a temp workaround of just multiplying the lightmap color by some kind of a number > 1 here:

OpenSource/src/render.c

Line 401 in 454773e

"vec3 lm = texture2D(u_lightmap, v_lightmap_uv).xyz;\n"

E.g. "vec3 lm = texture2D(u_lightmap, v_lightmap_uv).xyz * 2.f;\n"

Another option would be to disable lightmaps completely:

OpenSource/src/material.c

Line 132 in 454773e

ctx->mat->shader = MShader_LightmappedGeneric;

Change it to ctx->mat->shader = MShader_UnlitGeneric;
