I had an object with a 24 BMP on it and it worked ok but now I installed 0.4.2 and i tried to put a 32 BMP texture.When I run the program the object is white,without any texture.
Any ideas?
Thanks

Hey,
I had an object with a 24 BMP on it and it worked ok but now I installed 0.4.2 and i tried to put a 32 BMP texture.When I run the program the object is white,without any texture.
Any ideas?

Re: 32 bit texture problem
check out this thread http://irrlicht.sourceforge.net/phpBB2/ ... .php?t=517 .. use a 32bit tga or png instead of bmp .. what a waste of memory!Cleves wrote:I had an object with a 24 BMP on it and it worked ok but now I installed 0.4.2 and i tried to put a 32 BMP texture.When I run the program the object is white,without any texture.
dumb question: does it really matter? I always thought DirectX uncompresses the bitmap anyway before putting it into texture memory... I can't imagine the graphics card doing e.g. jpeg nucompression on the fly while rendering. So the only thing you would save is harddisk place.use a 32bit tga or png instead of bmp .. what a waste of memory!
But I'm not sure...

when you load the texture into ram it's true that it's stored uncompressed, but when the file is sitting on your hard drive a .png can be up to 90% smaller than the same file in .bmp format AND it's a lossless compression so there is no reason not use it... .png also give you 8bit transparency, which is not available with .bmp
why waste the your own (and the end-users) hd space for no reason?
all my image files for the irrlicht project i'm working on are .png (except for the .bsp textures, which are jpeg anyways which is good enough).
