For many years now I have been using Blender and its features to speed up my workflow to create environments. Linking Mesh Data between objects and using Modifiers to quickly create non-destructive and semi-procedural models. I found multiple techniques helped me to iterate during production and quickly adapt my work to feedback and changes.
I hope this is of interest to you and maybe you have additional tips and tricks. If so please don't hesitate to share them in the comments.
