With Halocline, you can bring your real production environment to life virtually - including steel beams, window fronts and ventilation systems. To ensure that the glb. files of your hall are optimally displayed in Halocline, they must be prepared beforehand - ideally with Blender.
These instructions show you step by step how to prepare your hall correctly.
Requirements & format specifications
Halocline supports the following gITF/gLB formats:
- Recommended: gITF Binary (.glb)
- Accepted: gITF Embedded (.gltf)
- Not supported: gITF Separate (.gltf + .bin + textures)
Please note:
- gITF versions: Halocline supports gITF 2.0
- Compressions: Draco Mesh Compression is not supported
- Unit/Scale: 1.0 unit = 1.0 meter
Goal: High-performance, lean and compatible hall files
Please note the following to ensure that your hall works without problems:
- Maximum dimensions: 500 x 500 x 20 m - larger halls cause performance problems.
- Data reduction: Remove all irrelevant objects (e.g. annotations, layers, textures).
- Simplify polygon mesh: Use meshes with the lowest possible resolution.
- Combine objects: Combine similar objects (e.g. same materials or groups) into one mesh - this reduces render load.
- Only export visible objects: All included objects must be visible & rendered.
Step-by-step instructions: Preparing the hall with Blender
Blender is a free 3D modeling tool that is ideal for editing .glb files.
1. Import .glb file
Import your existing hall or CAD model into Blender. If the file is not yet in the appropriate format, convert it to glTF format (.glb recommended) beforehand.
2. Adapt the orientation of the hall
The hall must be rotated by 90° along the X-axis so that it is positioned correctly in the Halocline coordinate system:
- Select object
- Press the R key → then X → 90 → Enter
(this command corresponds to the shortcut rx90)
3. Insert floor level
Halocline requires a defined ground plane on Z = 0 to ensure correct navigation:
- Shift + A → Mesh → Plane
- Then S → 100 → Enter
This creates a ground plane with an edge length of 100 m at height Z = 0.
4. Finalize preparation
You should make sure before exporting:
- There are no duplicate geometries.
- The model is organized, sensibly grouped and clearly named.
- The file size and number of polygons have been reduced to a reasonable level.
Then export the model again as .glb (gITF binary) with the correct scaling (1 unit = 1 meter).
The finished hall in Halocline should now look like this:
