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.
