Trouble with overview image

Wrong map image dimensions in overviews/gmdm2.bmp

That's the error I get (except that Valve actually writes "dimesions").

The image is 1024*768 @ 256 colours.

Any ideas?

I think it has something to do with the .txt file that accompanies the .bmp - I've seen this before but forgot how I corrected it.

does HL acknowledge only 256 colors?

seems kinda low to me, think about it, it has to be a BMP, and not a JPG, so maybe formatting it so low in colors will cause it to error out :sad:

Hmm, I thought it had to be a .tga.

nah its bmp

The Valve overview images are all 256 colour BMPs at 1024*768, so I don't think it can be the format

goll, when u took the screenshot did you make the txt?

This is the text from gmdm2.txt, located in the same directory as the image (....loada Steam crappo/Half-Life/gmdm2/overviews):

// overview description file for gmdm2.bsp

global
{
ZOOM 2.15
ORIGIN 115.38 -881.69 -312.00
ROTATED 1
}

layer
{
IMAGE "overviews/gmdm2.bmp"
HEIGHT -1537.00
}


 

lol, Thats not gonna matter to me if I didnt take the screenshot with the info in it m8

I don't understand 

Do I have to do anything differently due to gmdm2 being in its own mod?

m8, I think u may have perhaps just copied the info from a different image?

dev_overview 1 - info & details appear in the console & along the top, you need to screenshot this to keep the info for when u make the txt

dev_overview 2 - take a shot of this, This is your actual .bmp overview.

make the txt & enter the corresponding info from dev_overview 1 into it.

Hmmm.  I could've sworn that's what I did.  Might try again just for luck....

id give you a hand but dev_overview 1 doesnt seem to work in steam, Or at least I just tried it and it didnt.

You need to get Steam to make a shortcut, and add -dev to it.  It fails to make shortcuts to mods though.

or just add it to the launch options. Im an idiot.

// overview description file for dh_spammage.bsp

global
{
 ZOOM 5.66
 ORIGIN 524.00 -264.00 80.00
 ROTATED 1
}

layer
{
 IMAGE "overviews/dh_spammage.bmp"
 HEIGHT -297.00
}

Ignore, edit finaly worked.

Umm...what am I supposed to do with that?  Your overview information looks just like mine, except obviously with different numbers and map names.

look at both posts to check if youve put the correct numbers in the correct place. looking at my numbers you can see where each one goes in the txt. Just in case you do actually have one in the wrong place or missing.

The only one that isnt written the same is height which is max on the dev

Okay thanks; I'll have another go when I get the chance.

btw, whats the command for spectator mode. Tried spectate in console & it told me spectator mode was disabled. I didnt see it in the options when I started a steam serv.

Also, is it possible to spectate if you are the server?

Okay, this is a little embarassing :redface:

I was saving the BMP in run length encoding (RLE), rather than normal RGB.

Overview BMPs must be RGB-encoded, it appears.

As to the bmp/tga thing... I've seen both work.
