Presagis Creator Tutorial Direct

Once your terrain is built, it is not ready yet. You need to run Database Compilation:

In the world of real-time visual simulation, training systems, and defense simulation, the environment is not just a backdrop—it is an active participant. Whether for pilot flight simulators, driving trainers, or urban warfare scenarios, the quality and performance of the 3D terrain dictate the success of the simulation.

Presagis Creator is the industry-standard authoring tool for creating optimized, real-time 3D databases. Unlike standard modeling software (like Blender or Maya), Creator operates on a floating-point, geospatial coordinate system and prioritizes performance over polygon count through its famous OpenFlight (.flt) format and the use of instancing, LODs (Levels of Detail), and culling nodes. presagis creator tutorial

This tutorial will walk you through the foundational workflow of Presagis Creator, from project setup to exporting a functional terrain database.

| Mistake | Fix | |---------|-----| | Huge untextured terrain | Add at least a low-res satellite texture | | No LODs on buildings | Create LOD_2 (box) and LOD_3 (flat billboard) | | Model flickering | Check for coplanar polygons → delete or offset | | Missing textures in runtime | Set relative texture path (not absolute) | | Slow viewport | Enable View > Show > Bounding Box mode | Once your terrain is built, it is not ready yet

Group nodes under Groups or Level-of-Detail nodes:

/root
  /terrain
    /ground_tile
  /buildings
    /LOD_1 (high detail)
    /LOD_2 (low detail)
  • Inside LOD node, create 3 children:
  • Tutorial Verification: Turn on View > Show LOD Ranges in the viewport. As you zoom the camera out, you will physically see the models swap.

    • File > Export > OpenFlight (.flt)
    Or Export > CDB for full synthetic environment. | Mistake | Fix | |---------|-----| | Huge

    Creator saves native .flt. However, your simulation engine (Presagis Vega Prime, OpenSceneGraph, or Unreal Engine) may need a specific format.

    Final Checklist before Export:

    Forget 4K PBR textures. Creator uses Palettes and Materials.
