i would like to play with point filtering
i modified the occurrences of gl_linear to gl_nearest
but only the 2d elements seems to render with point filtering
is there a way to achieve this or the texture filtering is done with shaders?
thx

The old engine does filtering in the shaders. But if you're running the new engine (which has been the default in SVN builds for a couple years now), check out Src/Graphics/New3D/Texture..cpp in CreateTextureObject().

thx for reply
i modified the two occurrences in that file, since i modified all gl_linear that i could find in all the files
but still only 2d elements, i'm guessing the tile generator, get's that point filtering look
the textures on 3d objects are still filtered
i have to mention i'm not a coder so maybe i'm doing something wrong
maybe Ian can give a second opinion

I didn't read Texture.cpp carefully. It is already set to nearest filtering. Turns out Ian is performing texture sampling in the shader, probably to emulate Model 3's non-OpenGL-compatible edge clamping. The shaders are in R3DShaderTriangles.h and R3DShaderQuads.h (normal and quad rendering, respectively). The relevant function is called textureR3D(). I'm not sure if Ian's engine supports the -frag-shader command line option to load external shaders but at the very least you can edit and recompile.

ah ok
thx again, i will try but as i said i'm no coder, and this shader business it's above me

i figured out and disabled the mipmaping too
everyhing is super sharp now
thx for the help
