hello in 2020 ^^,

i'm using immediate mode atm and got issues with transparency when using PVR_TXRFMT_ARGB1555 non twiddled.

Alpha information seems ignored , blending is enabled and blendFunc GL_ONE_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA

the problem may come from glTexEnvi(GL_TEXTURE_2D, GL_TEXTURE_ENV_MODE, GL_MODULATE); which seems to generate an error : saying INVALID ENUM


also

Is there any way to load and use paletted textures with libGL ?

thx
I'd recommend looking at Kazade's GLdc. As far as I recall all other OpenGL Dreamcast ports (Including PH3NOM's) are software rendered, but Kazade's is the only Hardware rendered one. You can find more help with GLdc on the Simulant Discord channel (Kazade and a bunch of other GLdc users live there)

can't find the discord channel you are speaking about.

so libGL should be replaced by libGLdc into kallistiOS ?

seems confusing ^^

Here's an invite link https://discord.gg/BDCbJP

I think eventually GLdc will be added to the KOS ports and replace libGL, but it hasn't happened yet. Also note if you want to do audio there is a port of OpenAL called ALdc (Made by the same guy).

Feel free to do it on KallistiOS Ports Nitro!
