external lightmaps problems

[Rav3n]

I'm trying to figure out external lightmaps.
So I'm following these instructions but i can't get it to work.
http://www.smokin-guns.net/viewtopic.php?t=1444
The shader makes the texture i apply it to appear as missing texture.
But that's not the only problem, when the higher resolution lightmap is generated it basically looks like a 1024x1024 black square with the original 128x128 placed in the corner.
Anyone got an idea what I"m doing wrong.

i know now why do i get missing image problem, in the shader i shouldn't use .jpeg or .tga extensions or r_findimage can't find it.
Now i got a new problem, the lightmap is high res as i want it to be, shader applies it and all, but there's a huge offset.

looks like _samplesize 1 has to be in BSP stage in order to get the lightmap of proper resolution.
however the blendfunc isn't blending the ightmap.

Lightmaps don't have an alpha channel so blendFunc blend doesn't work with it. Lightmaps usually use blendFunc filter.

I know i am using blendfunc filter, poor choice of words i guess. I should have said they're not being filtered.
It looks like external lightmap is replacing the texture.

Post your shader as well as the one generated by Q3Map2.

Code: Select all

textures/ut4_siberia/stone_wall
	{
        q3map_lightmapSize 1024 1024
        q3map_lightmapbrightness 2.0
        {
        tcgen lightmap
        map $lightmap
        rgbGen identity
        }
        {

        map textures/ut4_siberia/stone_wall
        blendfunc filter
	}
        } 

Code: Select all

// Custom shader file for high_res_test.bsp
// Generated by Q3Map2 (ydnar)
// Do not edit! This file is overwritten on recompiles.

high_res_test/7BBBA5E1C3B16F7FA2B3862B469EF80F
{
	q3map_lightmapSize 1024 1024
	q3map_lightmapbrightness 2.0
	{
		tcgen lightmap
		map maps/high_res_test/lm_0000.tga
		rgbGen identity
	}
	{
		map textures/ut4_siberia/stone_wall
		blendfunc filter
	}
}

This is how it looks like in game.
As you can see the lightmap has a big offset and it seems to be mirrored as well. Blendfunc filter isn't kicking in either.
I'm using 27's FS_q3map2_radbump_4a http://www.urbanterror.info/forums/topi ... -required/ to compile this but since I'm using shader instead of switches i think it shouldn't be affecting the outcome.
