Large Unit Graphics

[WedgeAntilles]

For a mod, I changed the .grp of the khaydarin crystal formation from from 128*128 to 3200*3200 and changed the size to 1600 up, down, left and right. When I looked at it in-game though, there was just a large square from the graphic in the upper left corner of where it was supposed to be, and a dot in the minimap at the center of where it was supposed to be. I could select as if it was all there by clicking and dragging, but other than the square of graphic and the dot, it was invisible.
I compiled and added it to the mod .exe like normal, I didn't do anything I don't normally do, and I've changed graphics before and they worked fine. The only thing I did different was changing the size, using a different GRP compiler, and using a graphics palette with the GRP converter.
Programs Used:
SF GRP Converter
DatEdit v1.5d
WinMPQ 1.63.0.0
StarCraft Downgrader 3

Anyone know what went wrong?


Edit:

I also tried replacing what I thought was a doodad graphic, but in SCMDraft, it was in the Sprites menu. However, the results were the same.

I just don't think StarCraft can handle the size, unless those measurements are the same as, say, a building or Carrier/Battlecruiser. I'm not familiar with unit dimensions, but I'm pretty sure that all who've tried to drastically increase the graphic (.grp) sizes have failed somewhat miserably.

(please correct me if I have posted a bunch of bullshit, thanks)

Try 255x255. There's your maximum size limit.

Or you can use a little higher, if you need to just for the purpose of centering your graphic.  The actual visible part must be no larger than 255x255, though, or the converter has to cut off anything past that.

I figured it was something like that, but I wasn't sure.
Thanks.
