In order to use your own art assets (model prefabs, textures, materials...) made by yourself or downloaded online or from AssetStore:

All you need to do is to go to the TW interface tabs, click on nodes and change their resources (e.g. prefab, texture, material...) plus all other needed parameters (e.g. density, input area mask) if you want to customize the placement.

So to have a graph and feed in your own art assets, you have 2 methods:

1. first is to create the entire graph and nodes by yourself by following our video tutorials and documentations plus getting help from us and our community
2. or go ahead and select one of the templates from the first tab and start editing its nodes and contents to customize Scatter nodes or any other settings you wish.

These video tutorials (along with latest tutorial series on our YouTube channel) will get you started on this topic:

 

 

 

 

Would love to see your creations with custom art assets like this on our #member-showcase channel on our Discord
