well… i would always recommend that a test map have the basics such as
an info_player_start or deathmatch… at least one allied or axis spawn and
the mapcoords set, just to eliminate all problems that might occur like
freezing and map crashing… as in setting mapcoords but setting them wrong
will cause the game to freeze.
but, if your shure there’s no problems with your map getting to start other
than the fact your textures are odd sizes and not powers of two, then it
has to be your textures. if you have eliminated all other problems then it
must be that.
your textures should be powers of 2, as in 1,2,4,8,16,32,64,128,256… ect
as in the 1st pic you posted, 586x293 should be 512x256… and yes there will
be problems of skewed images if you resized them all, and probable ( but not
always ) problems of not tiling anymore ( if they are tileable to begin with ).
basicly when you create textures for the game, you should stick to the
powers of two rule. i have not tested it myself to see if it will crash or freeze
with odd size textures, but i never use odd size textures anyways.
again, if you know your test map will work, if you didnt use the textures,
then it has to be the textures thats causing the problem.
