Unreal Engine/Blender

 I started off using the landscaping tool to do the centre stage part.

I then needed a 3rd party asset of a lava rock, which i was able to find on Turbo Squid.

I decided to go with just a rock texture but i multiplied the rocks and began creating the scene!

Some lighting and more rocks!

There were importing issues with Unreal Engine so i ended up having to Render in Blender. This wasn't good at all, but fortunately it turned out well at least in my opinion. It's in the uploaded file!
