I understand that it's not Mesa3D's fault, but r600g doesn't seem to adhere to
those drirc settings (yes, I changed the name of the driver to r600 in .drirc).

If I run Tropics as
ESA_EXTENSION_OVERRIDE=-GL_ARB_draw_instanced ./1024x768_windowed.sh
it renders normally at daylight, but the night scenes are totally wrong. It
prints lots of these:
GLShader::loadFragment(): error in
"core/shaders/grass/fragment_base_light_omni.shader" file
defines:
UNKNOWN,QUALITY_LOW,QUALITY_MEDIUM,QUALITY_HIGH,MULTISAMPLE_0,USE_INSTANCING,USE_TEXTURE_ARRAY,USE_DEFERRED,USE_OCCLUSION,USE_REFLECTION,OPENGL,USE_PSEUDO_INSTANCING,USE_PSEUDO_TRANSFORM,USE_ARB_BLEND_FUNC_EXTENDED,BASE_LIGHT_OMNI,OMNI,SHADOW,NOISE
0:460(18): error: syntax error, unexpected NEW_IDENTIFIER

If I run without that override, only the textures at the root ot the trees are
shown, and it prints lots of these:
GLShader::loadVertex(): error in "core/shaders/meshes/vertex_base.shader" file
defines:
UNKNOWN,QUALITY_LOW,QUALITY_MEDIUM,QUALITY_HIGH,MULTISAMPLE_0,USE_INSTANCING,USE_TEXTURE_ARRAY,USE_DEFERRED,USE_OCCLUSION,USE_REFLECTION,OPENGL,USE_PSEUDO_INSTANCING,USE_PSEUDO_TRANSFORM,USE_ARB_BLEND_FUNC_EXTENDED,HAS_ARB_DRAW_INSTANCED,BASE_DEFERRED,ALPHA,MESH_SKINNED
0:171(53): error: `gl_InstanceID' undeclared
0:171(76): error: Operands to arithmetic operators must be numeric
0:171(76): error: Operands to arithmetic operators must be numeric
0:199(39): error: `gl_InstanceID' undeclared
0:199(42): error: Operands to arithmetic operators must be numeric
0:199(19): error: cannot construct `ivec3' from a non-numeric data type
0:199(58): error: Operands to arithmetic operators must be numeric

I'm not an expert on driver development, but IMHO this has to be fixed somehow.
Either persuade unigine devs to fix their code, or implement a proper
workaround.
