To maximize your workflow and ensure that the assets function as intended we made this quick guide that will help you get started.


Recommended Settings

These are the settings that we feel will work best with your game engine or 3D software.

Grid

Grid Size, Axis and Alignment
The ideal grid block size is a cube with a length of one unit. The models are designed to fit in a same sized cube and by using the recommended grid size it will be easier to place and maneuver the models.

For Unreal Engine 4 users, the models are scaled up to 1.1 to fit the UE4 mannequin. Use a 10 cm grid to snap meshes together cleanly.

Increment Snap

Move
By having the move increment snap set to 1 unit will make the workflow smoother and faster. The models were designed in a 1×1 square to make the different building pieces fit together nicely and enhance the building workflow.

Rotation
All the models have been tested to ensure the they will fit and work when being rotated 90°, 180°. Other rotation snap could be used for some models but there are no guarantees that they will work for all the models.

Scale
The models could be scaled up or down but to ensure that the models function correctly the scale snap should be set to 1[2] unit across all the axes, meaning no stretching in one of the axes.

Optimization

These methods will help you reduce the processors workload and save memory space.

Unity Game Engine

One way to optimize this asset pack in unity is through “static batching”. What Static batching does is that it allows the unity engine to reduce draw calls for geometry of any size providing that they use the same material and does not move (static).

To activate this feature, you will need to mark the game object and check the “static” checkbox in the inspector.

General Tips

If you want a certain color wall you could use the wall models (interior and exterior) named “Plain” and apply a solid color material to it, you could then even choose different roughness, metallic and other setting for this specific wall.

 

If you cannot find the piece that you need, try using two or more to create the missing piece. For example, if you want to create an inside facing corner for the interior try using two small interior walls.

 

 

To have the best performance results for buildings that are not interactable/enterable, we recommend using a 3D software to create the buildings and then combining the different parts (models) into one object or mesh then export it to the desired game engine. This will reduce draw calls reducing the CPU’s workload and saves memory space.

[1] These settings are optional and depend mostly on the user.
[2] The scale step could be set to 3, 5 or any number. The only requirements are to use whole numbers and have the same number across all the axes.
