lightmap export/import

(ailmanki) #1

I am trying to import the lightmaps into the bsp,

here the steps I do:

first convert the map to quake3 format (works fine, well dunno if it works with q3, but the vrml converter can use it.)
q3map2.x86 -game et -convert -format quake3 maps/goldrush

then import the lightmaps

[***@*** baseq3]$ ./q3map2.x86 -import -v maps/goldrush_c 
2.5.17

this does not work in any case, interesting is, that if I delete the folder containing the lightmap data, the folder gets created, but its empty.
Also it doesn’t matter if I try it directly on the et version (without converting firstly).

I tried to understand the source code (https://zerowing.idsoftware.com/svn/radiant/GtkRadiant/trunk/tools/quake3/q3map2/lightmaps_ydnar.c) but that did not really help.
From source I would expect more errors, but the above output is all I get…

I searched the forum for “export import”, I also searched with google… but there is none with the problems I got…

It would be beautiful if somebody could tell me how to import the lightmap, cause I suppose then q3bsp would work correctly, and be able to make a almost perfect preview… (http://home.snafu.de/hg/vrml/q3bsp/q3bsp.html)

Hmmm, never used import but I googled for it.

The explanation of -import on Wikibooks warns that the lightmaps can only be imported in the BSP they were created for. This means that you should probably run the -import phase first and then convert to Q3 format.

Also, why are you talking about the lightmap folder? I thought the whole point of -import was that the files in the lightmap folder are written into the BSP so you don’t need them anymore.

I tried to import without converting to quake3 bsp type, but that gives the same result.

I mention the creation of the folder, cause I had first the feeling its looking in the wrong path… but since it gets auto created in the correct place (when using -import), I think the paths are correct.

I think it doesn’t matter if the lightmaps are from another bsp, just the lightmap would be very incorrect.

I’m going to bump the tread up.

Since one stove can save half of the coal, if I buy two, no coal will be needed!"Although the world is full of suffering, it is full also of the overcoming of it.
