Subject: Use a dummy transmittance lookup texture to render the lookup in Sky
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=5ced451549e2238bb1195d03419437a395b9afec;hp=5ced451549e2238bb1195d03419437a395b9afec;p=libs%2Fgl.git

Use a dummy transmittance lookup texture to render the lookup in Sky

Ideally the compiler should optimize the shader so the texture isn't
used, but that'll take some extra effort to implement.
