Im making a an modular environment! let me know what you like and don't like and help me make it epic. I am pretty far through the block in enjoy! Concept
We have good tutorials on the modular page. Blending together tiled textures is still very very relevant. http://wiki.polycount.com/wiki/Modular_environments
Depends on the game. If you have a regular grid, attached can be better. Infinite runner for example. But if more organic results are needed, then modular is better.
these kinds of systems could make town building and modular assets in games very easy and intuitive. I'd love to see this developed into something further
Welcome to Polycount! For the column normal map, try flipping the green channel. For the building UVs, take a look at modular techniques. http://wiki.polycount.net/CategoryEnvironmentModularity
Can you show us the degree to which you broke down the assets to acommodate modularity. Loving the touch with the glowing eyes at the end of the tunnel.
