Steam workshop

Can I use all assets in the asset store for my (commercial) game?
The license of the Leadwerks Steam workshop states that everything that can be downloaded is royalty free unless stated otherwise. This means you can use all models, texturs, sounds, scripts and shaders in your commercial project without having to pay for it. Although it is not required we do encourage to give credit to those who earn it.

Can I upload payed items to the workshop?
Yes. Have a look here: http://www.leadwerks.com/werkspace/page/tutorials/_/workshop-r11#section5

Publishing

When I publish my game, a different scene is loaded then the one opened in the editor. Why is that?
Running your game from the editor loads the map that is opened in the editor. When published, the map is loaded you have specified in main.lua. You can find this file in the root of your project.

Assets

How do I import models, textures and sounds in the editor?
The editor does this for you automatically. As soon as you drag items in the editor or in the project folder, the editor will detect the changes and import them for you. If you edit textures, models or sound in an external program, the editor will also pickup these changes and re-import them automatically.

Textures
Textures are automatically converted to the tex format.

  • jpg
  • png
  • dds
  • bmp

Models
Models are automatically converted to the mdl format.

  • fbx

Sound

  • wav

Can I export my CSG brushes?
You can save CSG brushes as a prefab but you can not export you CSG brushes as fbx, obj etc. This has been requested though but is not confirmed to be part of the editor.

I cannot drag any textures on my models. Why is this?
You have to create materials in order to see textures on models. Simply right click on a texture in the asset browser and select 'Generate material'. You can also 'batch generate' materials via the tools menu.
