I used 'search' first so don't yell at me.

Screenshot says it all:

I've tried this with multiple formats, and in the samples as well as my own project, with the same results. The texture is about as simple as you can get:

I'm not doing anything tricky with the code, either:

Code: Select all

// default skybox
video::ITexture* pTex = m_VideoDriver->getTexture( "Textures\\def_skybox.png" );
m_SceneManager->addSkyBoxSceneNode( pTex, pTex, pTex, pTex, pTex, pTex );

What's the deal?

This is a discussion about something else but people have posted the solution to your problem

No, that doesn't actually solve the problem.

I'll just mirror the skybox textures before I export them. Works fine.

There's an older patch for that here: http://irrlicht.sourceforge.net/phpBB2/ ... torder=asc

I think I used that patch and it worked (I'm not 100% sure if it was from this thread, as I did patch that more than a year ago and had completely forgotten about it).

Maybe that did work under an earlier version but in the current build you end up with only one poly on each face. Or at least, I do.

The following however does work; each face is textured as you'd expect looking towards each direction:

I have fixed the skybox. You need to update existing skyboxes, though. Exchange right and left texture, rotate up-texture 270 degrees clockwise, and rotate down-texture 90 degrees clockwise.
I have checked the new orientation with TerraGen skyboxes which work out of the box.

The skybox is backwards?
