Make sure you install libtxc_dxtn and you may need to build mesa with the
--enable-texture-float configure option.

I had no x86 libtxc_dxtn, so I compiled it for x86 but no change, shaders still
seem to fail at compiling.

I tried installing lib32-libtxc_dxtn from AUR (I use Arch) and still bad
rendering. How can I test libtxc is installed properly for x86 ?

And I do have the --enable-texture-float configure option.

Still happening with 32 bit mesa 9.1.3 and libtxc_dxtn 1.0.1.
Output is the same, shaders fail to compile

Unigine has some known problems, so you need to set the following environment
variable to activate workarounds in mesa:

  force_glsl_extensions_warn=true

This should be enough for Tropics and Sanctuary IIRC, Heaven additionally
requires

  MESA_EXTENSION_OVERRIDE=-GL_ARB_shader_bit_encoding

Thanks, exporting force_glsl_extensions_warn=true does fix the rendering of
tropics!
Should I close the report or is it considered a temporary workaround?

As a side note, exporting MESA_EXTENSION_OVERRIDE=-GL_ARB_shader_bit_encoding
does not change anything for me in heaven 3.0. It has always been rendering
correctly, so the override does not fix anything, or maybe I never stumbled
upon the missing parts I am supposed to see...

Maybe it depends on h/w and or settings (defaults I suppose may be set
according to what heaven detects - untested).

I just tried on my HD4890 and without that I don't get any lighting/nice
effects so it looks very plain/matt.
