--- Comment #4 from maxijac@free.fr --- 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.

--- Comment #6 from Vadim Girlin ptpzz@yandex.ru --- 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

--- Comment #8 from Andy Furniss adf.lists@gmail.com --- (In reply to comment #7)

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.
