Irregular size textures ?

by Andy Wright · in Artist Corner · 03/23/2009 (5:41 am) · 2 replies

Hi, Im trying to work out why my dif isnt loading ingame, does torque have issues with irregular size textures ? the one in question is 1024x640... or would i have to resize to 1024x512 so its to a power2 size and rescale in constructor?

Or would 11000 surfaces more likely be the issue ?

It compiles to dif ok with no errors... im a lil bit konfuzzled

problem fixed, was the texture size... suprising, ive used smaller textures that were odd sizes for brick detail trims and road curbs etc and had no problems that i recall of

You can have irregular texture sizes, but they must also multiply to a power of two. The reason people recommend using 1024x512 and 1024x1024 is that multiplying a number that is a power of two by another number that is a power of two will always result in a number that is a power of two. You can't reduce the number 640 to a bunch of 2x2x2x2x2x2.... etc. eventually, it has a five.

1024x640 results in a number that is even (divisible by two) but not a power of two. I can't remember off the top of my head, but there are irregular texture sizes that consist of two numbers that aren't powers of two that multiply out to a power of two. If you don't know any, then sticking with using only powers of two is a sure fire way to end up with a kosher texture size. 64x32 works, 1024x128 works etc.
