I have been the lead modder for the campaign and battlemap for Roma Surrectum 2, and was involved in the initial creation of the ccampaign map (based on satellite and topographical data) as well as the customised battlemap environment with all new terrain textures, trees, lighting, skies and grass. During 2011/2012, I developed this further with updated lighting settings and terrain textures to enhance the atmosphere and realism.
Below are some screenshots of the work done in 2012:
