Software renderer (correct output)

The R600 driver misrenders the first demo of Irrlicht (irrlicht.sourceforge.net) when edited to use OpenGL instead of irrlicht's software renderer.

The demo loads an animated md2 model with a bmp texture.


Tested on Mesa 7.8.2 and 7.9, r600 fails on both, software renderer works on both. Screenshots attached.

HW: Radeon HD4350

This is still there with Irrlicht 1.7.2.

On the Irrlicht forums it was pointed out this model uses a NPOT texture, and indeed scaling it to powers-of-two makes r600 render it correctly.

Please test with r600g, we don't actively support r600c.
Comment 5 Lauri Kasanen 2011-04-29 04:32:32 UTC 
Works on on today's git and r600g.
