Post by: JoeSox on March 03, 2012, 03:19:08 PM

Has anyone have a clue why avatars/bots are too dark in my map?
I have tried the same sky/shader in a smaller map to test and avatars/bots look fine.
Maybe the shader q3map2 makes? (see attached if needed)

off-topic: your map looks like AMAZING!

on-topic: maybe you need to set something like map over bright bits or another global illumination var in the map?

Agreed, the map looks awesome!

My guess, OA is naturally dark. I have to ramp up the gamma quite a bit to get the bots and normal maps to look right. It appears you are making a VERY light map and that you're using little or no gamma when you run it. I bet it would be insanely bright for me.

I think I found a clue. When I build with "Q3Map2: (test) BSP -meta -flares, -vis -fast, -light -fast -super 2 -filter"
I get the following

I am not sure if you veterans have seen that before or not. Here is the settings for the sky shader:

Code:

textures/waterpark_sky/ely_hills
{
	qer_editorimage textures/waterpark_sky/hills_ft.tga
	q3map_globaltexture
	q3map_lightsubdivide 256
	surfaceparm sky
	q3map_surfacelight 200
        q3map_sun 1 1 1 80 200 60
	skyparms textures/waterpark_sky/hills - -
}

I played around with r_gamma but I don't think that is it as I never had issues before with my previous maps.

Q3map2 gamma doesn't brighten the lightgrid

I am trying

_minlight 25
_color 1 1 1

In the test build the darkness goes away. I'm doing the full build now to see if that will work or not. It probably will.

You should be using q3map_skylight (and q3map_sunExt).

From the shader manual;

Quote

q3map_lightSubdivide N

[..] Can have an increasingly "darker" effect when used with -fast. Compensate by raising the surface light value. For sky shaders, use q3map_skylight instead (see Appendix I: Light Emitting Shaders).
