[Bf-extensions-cvs] [1b95d391] master: The addon is updated for Eevee/Cycles - part 1: the atoms get now a useful color by using nodes (material properties). The color used in the viewport shading ('solid mode') has been removed since it doesn't make sense anymore. Otherwise one always has to manually choose 'using nodes' in the material properties.

The addon is updated for Eevee/Cycles - part 1: the atoms get now a useful color
by using nodes (material properties). The color used in the viewport shading
('solid mode') has been removed since it doesn't make sense anymore. Otherwise
one always has to manually choose 'using nodes' in the material properties.
