Pre-requisites
The model should only have main node for the body of the model and (if needed) strap_long node for the long strap. All names are case sensitive.
The model should be bottom-centered and face the same way as X axis.
3D model should have 1:1 scale.
All materials settings should already be done.
Installing the Add-on
Download the script here.
Go to Edit -> Preferences -> Add-ons -> Install, and choose the file you just downloaded.
Enable it by checking a checkbox
Open the 3D Model
Open your 3D model, which has the main node. You will see the Add-on window on the right side of the 3D Viewport. The numbers in the picture below correspond to the respective steps of this instruction.
Choose Font (1.)
Select the font file in the “Path to font” field (we recommend using the Roboto Regular font unless your client specifies another font).
Set Dimensions (2.a) (2.b)
Enter the actual Width, Height, and Depth in the respective fields (2a and/or 2b). You can provide dimensions in either cm or inches, or both. The script will use cm dimensions for subsequent Steps #3 and #4. If cm dimensions are not provided, it will convert inches to cm. Do not enter more than one decimal digit in either input field.
Resize Model (3.)
If the 3D model already has a 1:1 scale and the model is bottom-centered, skip this step. Otherwise, use “Resize bag” to adjust the 3D model to a 1:1 scale. This will scale the model to ensure that the width of the main node matches.
Create Size Indicators (4.)
Click on “Create size indicators” to generate dimension indicators with the numbers you entered in Step 3. This will create nodes for both cm and inches using the font provided in Step 1. The length of the dimension lines will match the cm sizes from Step 2 or be recalculated from inches if necessary. The dimension text will match exactly what you entered in Step 2. If nothing was provided, it will be converted and rounded to the nearest decimal digit. If you used “Resize model,” check the size and position of the bag and adjust it to match the dimension indicators if there is a mismatch.
Create Cameras (5.)
Click on “Create cameras” to create placeholders for three cameras. Each camera will have two objects:
An empty point, which serves as a pivot point for this POI and will be centered on the screen in the 3D Viewer.
The camera itself, which indicates the line of sight.
Adjust the cameras to get the POIs you need. Refer to the video at the bottom of this page if you need help with this step.
Export (6.)
Click on “Export” to export the model to a gltf/glb file. This will ensure that all elements are exported correctly into a format that the Holostep 3D Viewer understands.
