Check out this great work from one of our recent MA students Sophia Ingledew.
This is footage from her final project for her Masters and features an Orcish blacksmith's forge set into a volcano.
All assets and VFX were created by Sophia, and all textures were created procedurally in Substance Designer. The final environment was put together and presented in UE4.
