Blue Boxes!

[Ardnived]

I am trying to use images in some custom UI for different parts of a couple maps. But for some reason some of the images keep appearing as light blue boxes instead of what they should be.

• I cannot perceive any pattern to why some do this and why some don't
• The same images consistently appear blue over multiple tests.
• This occurs regardless of whether the image is being references directly or through a variable.
• All the files where this has occurred have been .dds, I have made no tests with .tga

If anyone knows what might cause this or has any ideas on how to fix it I would greatly appreciate it (And of course rep).

Check to make sure that your .dds files are the right dimensions. Try making sure they are all multiples of 8, otherwise shit can fuck up.
Also, save your map after importing files. If the problem persists, try closing/reopening it.

I see, both dimensions in a multiple of 8? I don't think that is the case for my images.

Yeah I made sure they were imported properly.

EDIT:
Yep looks like that was the problem, thanks

Its cause dds probably uses jpeg compression. Especially if it is jpeg 1 compression it breaks it down into blocks of 8*8 for encoding. Although jpeg is designed to be able to handle this with varying degrees of sucess, it sounds like eithor the converter you used is crap (seriously messes up with non multiple of 8 demensions) or that blizzards decoder is fussy and is designed to reject loading any non multiple of 8 image even if the file is a valid jpeg.

To me, this reaks of the converter you used being badly made.
Even WC3 lacked good converters, as virtually none supported palleted blps.

I used Graphic Converter, they display fine in previews and in the editor. Just not the game.

Well in that case it is probably a SC2 texture mapping bug. It loads them fine (why previews work) but when it trys to map them to textures it fails due to the odd size of them. Basically the previews are probably not D3D accelerated while ingame the interface should be, and the glitch occurs when mapping an odd dementioned image into textures.
