Khe Sanh - Part 2 - Burning Lands Vietnam

Welcome back, you can now set a reminder for when we go live on Kickstarter by clicking the link here.

In part 2 of the development of Khe Sanh, in this article we will be showing off the detailing also know as set dressing, as well as a goodie.

Over the last couple of months, we’ve made a big effort to push the quality of Khe Sanh’s environment art to a higher level, developing shaders and workflow’s to easily add dirt and grunge onto most of our art assets. This allows us to have high quality and very performant tiling base textures shared across multiple assets while still having the benefit of world relevant details (dirt gathering on top of objects, grunge and wetness seeping up from the bottom etc.) that ground the models into the scene and help us achieve that dust covered Khe Sanh vibe.

We’ve also leveraged Unreal’s Runtime Virtual Texturing and Virtual Heightfield Mesh technologies to make sure rocks, roads, dirt mounds and other objects blend seamlessly with a highly detailed and bumpy terrain. One huge benefit of this new system is that unlike traditional tessellation techniques, all the little bumps and lumps of mud and rock in the terrain even cast realtime dynamic shadows which really make the landscape come to life when the light’s at a low angle.
