Painter tileable textures

To ensure the landscape textures are cohesive in the
painterly style with the rest of the rocks of Tethered,
make tileable textures using Substance Painter by
following these simple yet effective steps.
With our hi-res mesh ready and created in ZBrush
as a tileable sculpt, export it in preparation. Next we
create a low-poly mesh to the same dimension with
UVs that are 0 to 1. Duplicate it four times and weld
to each subsequent seam side. Load your meshes
into Substance Painter and ensure your max front
and rear bake distances are adequate, then bake
your data. With a similar process of using mask
builders (as seen with the rocks), we can generate
09 the painterly look we want. But now we have the
ability to paint across all the seams to make our
textures tile flawlessly.
