[Basic Tutorial 2] texture problem (mipmaps?) [solved]

Post by Lafazar »

I am trying to run basic tutorial 2 after finishing basic tutorial 1. Everything works fine, but distant textures on the ninja are replaced with the textures from the robot used in tutorial 1. When I get closer they are replaced with the ninja textures. This does not happen, when I run tutorial 2 first after booting the computer.

It seems the mipmaps are not generated correctly (even though the log claims they are). Is this a bug in the code or could it be a problem with my graphics card driver?

I am using OGRE 1.4.9 & MinGW C++ Toolbox with code::blocks on an ASUS EEE 900 (yes, integrated graphics, don't laugh)

There's a sticky in the General Discussion forum about it: http://www.ogre3d.org/phpBB2/viewtopic.php?t=41547

Thank you very much for your answer. I read the thread you linked, but it seems to only concern Nvidia drivers. I have Intel integrated graphics (Intel 915GM). But I guess there could be a similar error in those drivers.

However, there is one strange thing I found: This problem ONLY happens with basic tutorial 2. I compiled ALL of the demos that came with the SDK and they all run perfectly fine (except those using features my card doesn't support of course), without any mipmap corruption at all.

It seems to be a specific problem with this tutorial, or at least the ninja mesh used. Replacing the Ninja mesh with something else fixes the problem, but the problem also appears when loading any of the following meshes in tutorial 2:
jaiqua.mesh
ninja.mesh
razor.mesh
RZR-002.mesh

All these meshes can also be loaded in the Ocean demo and razor.mesh appears in the SkyBox demo. I do not experience any mipmap corruption at all in these demos.

I do not have the reason, but you if you want to suppress this problem, you can suppress mipmap in your app.

Ogre::TextureManager::getSingleton().setDefaultNumMipmaps(0);

(I am not sure, but I think it's to be done in ExampleApplication before loading the ressources, anyway you can try it after -that is to say in your scene creation-).

good luck!

Thanks, it does indeed suppress the problem. But I would still like to find out what causes it. It's just strange that it only happens in this tutorial and not in any of the demos that use the same models.

Edit: It is a driver problem. Forcing texture compression in the driver settings fixes the problem. I guess the demo applications force texture compression too.

No, we don't. If there's something you did which helps these chipsets (I don't have a test machine with this particular card), please submit a patch.

I'm sorry, patching this in OGRE exceeds my abilities, I'm just starting to learn OGRE. All I can do for now is forcing texture compression in the OpenGL settings of the Intel Driver:

Image

However, from my limited understanding, it seems to be similar bug with uncompressed textures as the one in the Nvidia drivers, so the same patch with GL_VENDOR = Intel might fix it.

Just for clarification, are the textures for these models loaded as uncompressed by default (exampleApplication.h is responsible for preloading if I understand correctly) or is there something else they have in common? Because mipmap corruption only happens when loading these specific models in basic tutorial 2 (another observation: it also causes the ground textures mipmaps to be corrupted which loads fine on its own):
jaiqua.mesh
ninja.mesh
razor.mesh
RZR-002.mesh
