It would seem that the map artists have scattered group photos of themselves together with developers and other staff around the new HD maps.
These were found by “Arcane Spirit” one of the RSR Discord members.One each on Himmelsdorf and Ruinberg then two on Siegfried Line.
Here we also have several from the Russian blogs.
• 4 photos on El Halluf;
• 2 on Fjords;
• 4 on the new map Glacier.
It seems even SerB is in them, but maybe it’s just a similar person.
And on the last photo of the Render Team the creator of the Core engine (far right).
