"Get Relief!" a Relaxed Cone Step Map Generator


Demo Video | Get Relief! Wiki | Version 1.2.2 Out Now!


Convert any flat texture to one with depth, all you need is a heightmap, the tool will take care of the rest.


This plugin aims to simplify and demystify different Relief Mapping techniques for materials. The engine supports Parallax Occlusion Mapping (POM) but to get good quality results might require a cost-prohibitive number of samples. Instead this plugin provides RCSM (as described by Nvidia GPU Gems 3 : Chapter 18) which is a method for creating a helper texture to reduce the required number of samples for appropriate occlusion substantially. This technology has been used in many recent AAA games, but often is out of reach of Indie development.


Get Relief! wraps up the efficiency and behaviors of RCSM into an all in one package for generating helper textures with production ready workflows.

In the future more types of relief mapping techniques will be incorporated.



Version 1.2.2
  • UE Version 5.2 crash fix on save.



Version 1.2.1
  • UE Version 5.2 Officially Supported.
  • Cosmetic code cleanliness updates.

Version 1.2.0
  • UE Version 5.1 Officially Supported.
  • Added "Reference Plane" to the materials, allowing the user to allow the relief to break the surface. Note: This will cause sorting and motion blur issues, so use sparingly.




Version 1.1.1
  • UE Version 5.1 Support Added
  • For now, use the 5.0 version, you will need to manually install, until 5.1's full release.




Version 1.1.0
  • RCSM generation speed increased by 100x
  • On a RTX 3070:
  • Before: 1024x1024 - 10 Minutes
  • Now: 1024x1024 - 9 seconds
  • Lower resolution RCSM generations use source MIPs appropriately now, reducing artifacts.

Technical Details

Features:
  • Right-Click Menu on texture assets to generate RCSM or Height maps.
  • Modify height-maps at interactive framerates with novel cross-section preview.
  • Progress Bars, Auto-save, channel previews and more UX features.
  • Variable source height-map channels.
  • Generation Settings saved with the outputted texture files seamlessly.
  • AAA quality, versatile material functions for relief mapping on surfaces and decals:
  • Relaxed Cone Step Mapping (GPU GEMS 3: Chapter 18)
  • Improved Parallax Occlusion Mapping (Higher quality with few samples.)
  • Parallax Occlusion Mapping: Epic Version (Standard Engine POM, but with the graphed cleaned up for readability and modability)
  • Transform World Vector to Decal Tangent Vector.
  • Example Decal and Megascans materials to learn from.
