Learn how to export a model from Blender to Overgrowth.

Posted by Silverfisk on Jan 7th, 2011
Basic Props Modelling.

First we download Blender, then we create a simple model, make it smooth and unwrap it. Then we make a simple texture for the model and create the xml file that we later load in the game to spawn the object.

Dang... that's a pretty smooth workflow. So if you were to "save" the map and load it back up it would still be there?

Maybe I should start taking advantage of my pre-order...

Yeah, the workflow is much better than what I'm used to (Source engine). You can save it and load it up again and send it to other people or whatever you want. :)

Isn't it a bit weird that you define the spec level by adjusting the diffuse oppacity?!

The complete workflow is abit circuitous, but it's your own engine so I don't really care :)
Just hope that you will implement common workflow like from Cry Engine 2 ;)

Keep the vids coming!

I actually think it's pretty easy changing the spec in alpha channel, but since that doesn't work as it should in Gimp, David has said that he's going to perhaps change that in the future to use a separate picture to define the spec.

And it's actually not my engine, I'm just a fan of Wolfire Games. :)

I assume that it does not have any form of collision box? Still, great tutorial.

By default it uses the mesh as collision, but that was changed recently, so now you can use another object for collision if you want to.

That looks cool, very simple workflow. It however seems as if it doesn't matter where the objects are located as long as they are located within the main Overgrowth folder or one of it's subfolders. Whilst this allows for everyone that uses the engine to lay out the data the way they want it, I can foresee huge a huge mess in Overgrowth folders due to a lack set pipeline rules.

There has been some proposed guidelines for how and where custom material and assets live, so hopefully when the game is fully released, people will start to follow those techniques...

does the normal map only work for the donut thing or does it work for anything?

It works for anything. Ideally you'd want a normal map that's tailored for the object you're creating, but if you don't need a normal map or can't create on for any reason you can just use the blank normal map.
