[fixed] D3D8 Mip filtering (mip and mipless in same scene)

[kvakvs]

Im using mix of materials which have MIP levels, and which do not. Had the problem, when in some situations D3DTSS_MAGFILTER and D3DTSS_MINFILTER were not set correctly according to Material.UseMipMaps.

Here is what i found in "irr.video.CD3D8Driver.setBasicRenderStates"
texture stage state is not testing if UseMipMaps in last material changed in current material.

Code: Select all

if (resetAllRenderstates ||
  lastmaterial.TextureLayer[st].BilinearFilter != material.TextureLayer[st].BilinearFilter ||
  lastmaterial.TextureLayer[st].TrilinearFilter != material.TextureLayer[st].TrilinearFilter ||
  lastmaterial.TextureLayer[st].AnisotropicFilter != material.TextureLayer[st].AnisotropicFilter)

Changed this to:

Code: Select all

if (resetAllRenderstates ||
  lastmaterial.TextureLayer[st].BilinearFilter != material.TextureLayer[st].BilinearFilter ||
  lastmaterial.TextureLayer[st].TrilinearFilter != material.TextureLayer[st].TrilinearFilter ||
  lastmaterial.TextureLayer[st].AnisotropicFilter != material.TextureLayer[st].AnisotropicFilter ||
  lastmaterial.UseMipMaps != material.UseMipMaps)

Now works.
Thanks for attention

P.S. Same goes for D3D9Driver, also (possibly?) for OpenGL, cannot test OpenGL for now.

Ok, this just belongs to SVN trunk version. It's fixed now (was indeed only d3d, due to different update schemes).
