FOSS gamedev and creative worlds

Hello, I have a strange bug on Ubuntu 10.10 with the stable ppa :





I have a Nvidia graphic card.
This bug is only on this computer, not on my netbook with Ubuntu 10.10.
There is this bug with the official and non-official texture.

Thanks.

May be a driver problem, I've seen something similar in Minetest and other games.

On mine, the 4-5 blocks closest to the player in any direction render fine, but then some faces are missing from other blocks. I've not looked at the code, but perhaps it is to do with scaling the textures that are far from the camera.

Turn auto antialiasing off at your nVidia driver settings, this option causes bugs with opengl also on Minecraft

Since my uprage to 11.04, I haven't this bug.

That's due to Natty's new openGL library usage or your drivers were updated to close anti-aliasing off

Glad you got it fixed

The same on my Intel 82865/855GM graphics chip and Debian sid.

Friend told me that these problems are caused by Z buffer (AKA depth buffer). You should increase its resolution, I don't know how to do this from xorg.conf (if it is possible outside the game...).

Z buffer resolution can be chosen when requesting the GLX visual when initializing OpenGL - I don't know if Irrlicht interfaces the selection mechanism, if it does the issue probably could be fixed.

It is not Z buffer problem, but mipmaps problem.

Use only if you experience graphic glitches, it reduces video quality otherwise.

Do not use antialiasing and/or anistropic filtering from your GPU's control panel.
