Blender Installation

To use the add-ons, you need the 3D-Software Blender

  • click the following link to download Blender: Download Blender
  • after the download is finished, run the file and follow the installation instructions
  • if Blender was already installed before, you also have the option of adopting existing settings

Add-ons Batch Installation

We have prepared a package for you to install the add-ons automatically.

  • load and unpack the following package:Add-on Auto Installation
  • after double-clicking on the Install_Govie.bat file, the add-ons are installed automatically
  • after starting Blender, the entries GovieTools and GLBTextureTools appear in the Properties Panel (N key)
  • should there be a problem with the auto-installation, the add-ons can still be installed separately via Blender preferences

  • expand your portfolio with additional services
  • no additional external partner necessary
  • less overhead, simpler communication
  • we develop features, you produce your application

Govie Tools

The Govie Tools work best together with the Govie Editor

With the help of the quick export and preview functions, the model can be tested without uploading it to the Govie platform every time.


Export and Preview
export und preview funktion
  • in order to use the export function, the current blend file must be saved
  • now the export button can be clicked, whereby the model is exported to the GLB folder
  • after exporting the GLB, the filename of the exported file appears in the drop-down list
  • with the help of the preview, the model can now be examined

Using the visibility option, an object can be hidden or shown later in your application. Inside the preview, you can quickly check if the naming matches, and everything works as expected.


export and preview
  • select an object in the scene and click on Add Property in the visibility panel
  • after the export is finished, the filename of the exported file appears in the drop-down list
  • the visibility can now be tested in the preview
  • if you are happy with the result and everything works as it should, the file can be uploaded to the Govie Platform to be used inside a presentation

If the visibility is set for a parent object, this also affects the child objects. With the help of empty objects, visibility groups can be created to hide or show several objects at the same time.

Visibility - Groups

visibility grouping
  • create an empty object which serves as a parent for the objects that should be in a visibility group
  • select the objects you want to group and lastly the empty object
  • create a parent-child relationship by pressing CTRL + P 
  • finally, select all objects including the empty, and export them
  • click preview to try things out
  • alternatively, the whole scene can be exported if select only is unchecked in the export settings

The animation panel provides an overview of all animated objects. The identifiers of the objects and their animations can easily be edited here.


simple Animation
  • open the animation panel
  • as soon as a keyframe has been set, a new entry appears in the animation list
  • the title of the animation can easily be edited
  • after export, the animation title can be found in the preview window

Several animations can be combined by clicking the join button. After that, you can also rename the joined animation or separate it back to single keyframe animations.

Animation - Join

join animations
  • several animations can be combined into one NLA track
  • to do this, select all the objects whose animations you want to join
  • open the Manage Animations menu and merge the animations by clicking Join Animations
  • the combined animation can be renamed with Rename Animation
  • the merging can be undone with Separate Animation

The annotation menu provides a compact overview of all texts in the scene. Download this template and append the Annotation to have a starting point: Annotation_Text


Add Description
  • create text or append the pre-made labels
  • position the text with the help of the empty object
  • easily edit the text using the annotation panel
  • show and hide text via visibility property


Draco compression is sometimes not enough to reduce the file size. Draco essentially reduces the model geometry. If there are large textures involved, they must be scaled down separately.

Scaling Textures

Reduction of the file size through texture scaling
  • open the Textures menu
  • textures for the selected objects are displayed here
  • all textures in the scene can be displayed with the Show all Textures option
  • the target resolution and the file format can now be set in the global settings
  • after clicking on Scale Image, the textures are converted

AO maps can be created with one click on the bake button. After baking, the addon automatically creates a new node setup in your material, that allows you to include the AO map into the GLB File. The baking menu provides direct access to a variety of settings.

Baking AO

AO for single object
  • set the desired resolution and file format
  • set the sample rate for AO Baking (start with a low value for testing)
  • check unwrap if no second UV was added previously
  • if necessary, assign a name for the AO map (the default is AO + object name)
  • click on Bake Textures
  • if the Show Texture after Bake option is active, the baked AO map is displayed directly in the viewport
  • if you’ve opened a UV Editor window before, the baked texture is displayed here as well

A separate object group is created for each baked AO or lightmap. Use this to reselect objects again later. Using those groups, an individual map size can be used for baking different objects.

Baking AO - Groups

Beschriftung hinzufügen
  • new AO groups can be created by selecting different objects and baking them
  • the group can be selected using the dropdown menu
  • all objects of the respective group are selected by clicking on the mouse pointer icon right to its name
  • if an object has already been unwrapped, the unwrapping setting can be unchecked
  • for the final bake, the sample rate can be increased until the desired quality has been achieved

If a UV map has already been generated, the baking can be done without additional unwrap.

Baking AO - No Unwrap

no unwrap
  • ensure that a second UV map is already available
  • this UV map must be called Lightmap
  • now the Unwarp checkbox can be deactivated
  • If the Show Textures checkbox is deactivated, the AO map can be displayed later using the Preview Bake Texture

Detailed documentation of the menu items

Global Settings

these settings affect many other functions of the add-on

output resolution

Image size

  • important for baking and scaling of textures
  • if the original is selected before scaling, the original textures are restored
file format

File format

JPG – much smaller than PNG, but lossy

PNG – lossless compression with alpha channel



  • refers to the functions in the visibility panel
  • affect is used when switching between original and baked material

ACTIVE – the active and therefore last selected object

SELECTED – all selected objects

VISIBLE – all visible objects in the scene

SCENE – all objects in the scene

compute device

 Compute Device

CPU – often slower than dedicated graphics card, but uses main memory of the PC and therefore doesn’t run out of memory that quickly

GPU – should be selected if a dedicated graphics card is available and the scene to be baked is not too large

Bake Settings

First, you need to set the bake type. Each type has its own specific options.

Bake types

There are 3 different bake types within the bake settings:
Physical Based-, Ambient Occlusion- and Lightmap Bake

The number of samples can be set separately for each bake type. The higher the value, the better the end result, but the longer the waiting times!

PBR Bake

Allows you to transfer Blender’s custom node-setups into the GLB format (e.g. color ramps, RGB curves, procedural textures). The sample value can usually be left at 1. A higher value is only recommended for baking procedural textures.

Mute Texture Mapping – deactivates all texture mapping nodes for the duration of the baking process and should be activated by default

Ambient Occlusion Bake

This can be used to create AO maps for individual objects and groups of objects.

AO Distance – defines the size of the ambient shadow

A good value is between 0.1 and 1 and results in much less noise!

UV Margin – determines how much space is left between the individual UVs

Bake Margin – n-pixels are baked beyond the UV border to prevent visible seams

Unwrap – defines whether a new UV Set, with the identifier Lightmap, should be created

Denoise – uses a bilateral blur to soften the AO map

Lightmap Bake

Lightmaps are integrated into the existing material as emission nodes. The Govie Editor then inserts the lightmap into the lightmap channel. This is a workaround because the GLTF Format currently doesn’t support lightmaps.

Lightmap in Viewer – deactivate the camera light in the viewer or the diffuse light in the finished govie so the lightmap becomes more visible

Denoise – uses an AI-based approach to create a noise-reduced lightmap from color, normal and diffuse maps

Show Texture after Bake – the baked texture is displayed on the object (via Emission Shader)


The visibility menu is used to switch between the original and the newly created, baked material. What material is displayed depends on the selected bake type (PBR, AO, Lightmap) and the affect setting.

Show original material – if a baked material is available (with “Bake” in the material name), this will switch back to the original material

Preview Bake Material

Previously baked AO- and lightmaps can be examined using the preview function before the model is exported.
