Short description of error
In the render it only shows the objects that have emisions activate but they are black on transparent.(it should not be transparent to begin with)
after restart it works for the first render (that is very very slow) and if i whant to render again it gives me the same error.
the clouds have a basic volumetric shader with a voronoy texture for density (this is the problem generator)
and it persist after i unlink the texture, until i restart blender.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
