The grid is 3.6 x 3.6 x 3 meters in Blender. If you want to use the grid while moving these parts: make sure to search for ‘’unit scale’’ on the left in Blender, and set it to 10. When you are done, set it back to 1.

By default this number is already set to 10, Its very important that you change this to 1 when you want to export anything from this file.

To snap the wall pieces perfectly together, just hold CTRL while you move them in place, they will align to the grid connect seamlessly

The only thing not pre-made in this pack is the pool water, however, the material is included.

For this, just create a cube that fits in the entire shape of the empty pool. Create a cube projection UV with the value of 1.0 And apply the water material.
