Oh, nice, that came out smaller than the original png file! :-) blessed is the DDS and its dxt compression lol The thing is DDS format actually goes direct to gpu, as far as i know png and jpeg and a load of other formats have to go through some form of progressive compression before being read int...

well there are some black areas on that texture map so im guessing it has alpha? but it doesnt seem to have any fading alpha so no banding should occur from DXT3

i would guess that flight gears engine doesnt do mipmapping or at least is selective mip mapping, import that texture as a dds file with no mip maps, you shouldnt get any errors and it would have a smaller footprint on vram because of both that and the dxt3 compression

the way it works is once the Y gets to 1 the X keeps dividing by 2 until it too gets to 1 so whenever the Y gets to 1 i think 16384 will be at 128 then it will keep regressing to 64 x 1 - 32 x 1 etc until the image is at a 1x1 The texture size does seem strange to me, can you upload the texture some...

well each minimap is effectively 50% of the size of the texture that came before, so if 1 texture is 10Mb the next will be 5Mb and so on and so forth 13 times or in what you have set 15 times. That setting being changed is going to do the same thing for all of your textures that are png or jpg. The ...

Yeah, png. That may be your problem, as i understand it mip maps are generated automatically for png and jpg when imported into torque, with the hard coded limit of 13, this means each level the image drops by po2 till it gets to a 1x1. Because it isnt getting to 1x1 its throwing out that error. Yo...

I didn't create it, so I don't know why it has to be 16384, I expect the FlightGear artists just kept making it bigger and sticking more textures onto the bottom of it. It's only 256 pixels wide.
Ah okay, and what is the texture format is it png?

Could you tell me why your texture has to be that big?

Also could you tell me what format the texture is?
