GX_TL_RGB5A3

Post by OzzyOuzo » Wed Sep 20, 2023 1:59 pm

Hello,

i'm trying to add transparency to my paletted textures using GX_TL_RGB5A3

documentation says that MSB dictates both transparency and component format..

will it be for opaque texel/palette entry : msb is 1 (0x8000)

F E D C B A 9 8 7 6 5 4 3 2 1 0

MSB(1) R R R R R G G G G G G B B B B B

and for transparent : msb is 0

F E D C B A 9 8 7 6 5 4 3 2 1 0

MSB(0) R R R R G G G G B B B B A A A

???

In any case it draws opaque textures (blending is on)

Anyone has already succeeded with this format conversion ?

thx
