Please check out Sierra Division for Awesome New Art Packs! PurePolygons will no longer be creating any content.

Q: But Why??

A: Jacob Norris (PurePolygons) had been trying to run this venture as a side business for many years, while retaining a separate full time job. The time for creating the artwork, providing customer support, and keeping things updated was too overwhelming as a one man studio in addition to his full-time work. In 2022, with some friends, the idea for an entirely new studio was born. Sierra Division was co founded by Game and Film Industry Veterans and is the future of Top Tier Artwork available to the public. The company is dedicated to creating the highest quality artwork and providing welcoming and fast customer service. If you are looking for more PurePolygons Artwork, you can find Jacob and his teams work at Sierra Division. Thanks to everyone for the support over the years and the overwhelming positivity for the artwork. This is not goodbye!

Q: Does this mean PurePolygons is no more?

A: All current PurePolygons packs will remain active and updated to the latest Unreal Engine versions, but if you are looking for new artwork and assets on the Marketplace, Jacob (PurePolygons) is now dedicating his time fully to Sierra Division and the incredible team of people creating content there. Thanks again

Procedural Nature Pack

The rivers are all spline generated with a material that increases the speed of the river based off of the slope angles of the geo and adds foam to the water at the tops and base of any water falls. So there is no extra work on your part. Just place it and go!


Procedural moss placement on assets or vertex painted versions for the more precise individual.

Trees + Foliage:

Simply adjust the number of branches, angle, angle variance, twist of the tree trunk, wind intensity, up to 4 separate branch types per spline, and all of this can be found on each individual branch spline. Customize to your liking or copy and paste them all over! The branches randomize position and rotation, so no two are the same. It's even more powerful when you start swapping in your own assets!


High quality hand sculpted terrain materials. Turn tessellation on or off for next-gen looking assets.


And of course rocks with worldspace color overlays and normals so you can scale and rotate them to any size or shape

without any distortion to the rock material.

Easily export any spline generated models that you create. Simply by selecting the generated meshes and using the export function. This can even be a quick modeling tool for your arsenal!
