Room Test Demo

Ok, so following David Jone’s suggestion 😉 i decided to build a little demo of the room.

It’s modeled in Blender 2.63 and textures are from the game Return To Castle Wolfenstein.

Lights are baked into the textures. I removed the smoothing intentionally to give it an old-school / playstation 1 kind of look (good times…)

And yes, it’s a little dark… it’s suposed to be that way to generate a “scary” feel…

WARNING: no preloader, the file is about 2.5MB in size. Wait for it to load. Click below to open.

Click to open demo – Flash Player 11 required.

Blender to Alternativa3D note

When you scale/rotate an object in Blender (not inside edit mode), before exporting you should click CTRL+A to “reset” the object’s transformation and making it the “default” transformation. Also, when you do that, also reset the object’s normal, by selecting all the faces and CTRL+N.

If you dont do this, you MIGHT notice issues like faces looking in the wrong direction or the object being distorted in weird ways.

So in resume, when you get your object ready to export:

1. CTRL+A reset transformation: Rotation & Scale.
2. CTRL+N: inside edit mode, select all the faces, and click this to recalculate all the normals.

And that should do the trick.

Alternativa3d 8 Forest (work in progress)

I’m trying to make a forest in alternativa3d with los polygon techniques. So far i created 1 type of tree and multiplied several times changing position and rotation. I will have to do 2 or 3 more types of trees and several other objects until i finish, but so far is looking decent…

The only 3d body is the trunk, the rest are planes with textures with opacityMaps (the branches). I think that after i finish with the modeling, the addition of normal maps will make the forest look much better.

 

Alternativa3d 8 Fog!

Today David Jones posted a tutorial on how to create a fog effect in alternativa. This is apparently under development, so it’s not “official” and im guessing it can change at any time, but, for the moment, this gets the job done at the cost of editing a few lines of code of the engine’s sourcecode (but nothing too serious, just un-commenting lines)

More details here: http://davidejones.com/blog/1631-fog-alternativa3d-8/

This is the result i got (editing the example code called “demo example” that comes with alternativa )

Importing COLLADA (*.dae) from Blender 2.63 to Alternativa3d 8

When you export from Blender 2.63 to Alternativa3d 8 you wont be able to load the model at first try, you will need to add a “name” attribute in the DAE file in order to Alternativa3d to find the objects.

You must open the DAE with a text editor (it will be an XML file) then add a “name” attribute with the same value as the “id” attribute of each NODE element in this root:

%XMLROOT% -> library_visual_scenes -> visual_scene -> node

There you will see something like:

<node id=”level” type=”NODE”>

and you must change it to:

<node id=”level” type=”NODE” name=”level”>

To do this automatically, pre-parse the XML before passing it to the ParserCollada to add this attributes:

			var colladaXML:XML = XML(new LevelModel());
			var ns:Namespace = colladaXML.namespace();

			var xmlCount:Number = colladaXML.ns::library_visual_scenes.ns::visual_scene.ns::node.length();

			for(var i=0; i<xmlCount; i++)
			{
				var nodeName:String = colladaXML.ns::library_visual_scenes.ns::visual_scene.ns::node[i].attribute("name");
				var nodeID:String = colladaXML.ns::library_visual_scenes.ns::visual_scene.ns::node[i].attribute("id");

				if(nodeName == "")
				{
					colladaXML.ns::library_visual_scenes.ns::visual_scene.ns::node[i].@name = nodeID;
				}
			}
