3D Assets

Within the 3D assets section, users will be able to upload and view 3D models.
3D models can be added into dictionary items and can be viewed on the Explorer map.

Below is a table of contents to help divide the sections in this introduction for your convenience.

A guide to using 3D models in PAM

Adding 3D models help create a compelling environment, but too many 3D models can be overwhelming and heavy on computational resources. Below is a guide to using 3D models in PAM.

File Requirements - Please Read

• All 3D models need to be in a .glb format.

• 1mb file limit size limit (although 500kb is recommended maximum)

In your account, we strongly recommend that all uploaded 3D models have a combined total of no HIGHER than 2-3mb.

This means you will need to optimise the file size before uploading your 3D model into PAM, by reducing complexity and limiting/removing textures

When to use 3D models

Difference between a 3D model and an Extruded Structure

Technically the 3D models exist on a separate layer (illustrated below in Pink) within the PAM Explorer Map. Extruded Shapes are drawn in Map Editor and are used for identifying basic building structures. Extruded Shapes are less intensive on memory and recommended to be used when possible.

Refer to the photo below.

1. Simple Extruded Shapes

2. 3D Model - Lives in a separate layer to the map

When not to use 3D models

1. When it is possible to use Extruded Shapes - for example when a building has no real architectural features that can't be replicated by simple extruded shapes

2. If it requires too many models. For example you decide to add some trees along a walkway and then realise you need to add the trees everywhere

Things to consider

• Models should be created at their actual size in a 3D editor.

• The model will be positioned based on X,Y,Z axis set in the 3D software so you can position a 3D model above the ground. Note: You cannot adjust the model in the Z-axis in PAM.
  
  

• Colouring the 3D model should consider the surrounding environment. You want to avoid using too many textures and colours, especially with architectural buildings. They should blend in to the environment and not conflict with ‘Extruded Shapes’

   

   

• Textures on a model may be required for promotional items
  
  

  • Make sure textures kept to a minimum, and do not exceed 800 x 800px in dimensions

     

     

  • JPG medium quality OR PNG with Alpha supported
    
    

• Vegetation usually requires multiple models, although there is a maximum size of 1mb for a model, the file size should be kept at a minimum when possible. (e.g. small tree was 6kb)

• Models should MATCH each other
  
  

• The more models you add the more computational power you need to render. Therefore if you decide to add ALL the vegetation to make it realistic, it may require hundreds of 3D models and performance could be compromised

• Generally remove any detail in a model that is not required. For example in an architectural building, you only require the outer shell
