The first image shows the scale of the landscape - the little dots being the dino and human figures. The mesh was reduced in Balancer so that DS4.5 could handle the size of it. The texture though is massive at 90 meg (massive for me anyway). The second image is shown with a fog camera which then sadly loses the clouds in the sky but adds more realism (ie. atmospheric perspective). The bump map sadly both creates detail in the foreground and creates areas that look like errors. That is mostly the WIP aspect of this landscape.
Very happy with what World Machine is allowing me to accomplish at the moment. 
PS. The figures are just quick additions to work out the overall look of the land itself. Test and see what is needed.
