Texture filtering

[WaRzillA]

Hi,
Is there a way to disable texture filtering in the config file to get a pixelated look?
I tried adding seta r_TextureMode "GL_NEAREST_MIPMAP_NEAREST", but the game removes the line on startup.
Is there a different command or workaround I should use instead?
Thanks,
Seb

Hi Seb — thanks for the clear report. You found a real missing renderer control.

r_TextureMode is not an openQ4 CVar, and the intended Quake 4 setting, image_filter, was no longer registered or applied by the renderer. I’ve restored it in #130 for both OpenGL and Vulkan.

Once that change is merged, this gives the pixelated look you were after:

seta image_filter GL_NEAREST_MIPMAP_NEAREST

The value is saved and now updates loaded textures immediately, so no vid_restart is needed. Nearest-texel modes also avoid anisotropic filtering so it cannot soften the pixel edges; explicitly filtered UI/internal textures keep their authored sampler state.

I validated the change in a windowed single-player game/airdefense1 run: the sampler refresh was logged, the setting persisted to the config, live gameplay completed cleanly, and the engine-rendered capture showed the expected nearest-neighbour texture treatment. I’ll leave this issue open until the fixing PR lands.
