Documentation Articles

Overview & Architecture

OptiTerra core architecture — Texture2DArray optimization, 16 layers, and 90% GPU bandwidth savings.

Setup Guide

Step-by-step implementation for fresh terrains or converting existing terrains via OptiTerra Manager.

Shader Variants

Non-Tessellation vs Tessellation shader profiles, target platforms, and feature configurations.

Sampling Methods

Performance Mode (single-sample mobile) vs Fidelity Mode (parallel PC/Console) comparison.

OptiTerra Manager

Extending terrain layers to 16, per-layer Tessellation & Amplitude, and dynamic Rain Effect.

Optimization & Tips

Draw instancing, per-pixel normal benefits, resolution budgeting (CH 512, NOS 2K), and BC7 compression.

Texture Array Generator

Bonus standalone utility for creating Texture2DArray flipbooks and packing terrain textures.
