Let’s see the result.

Now will make some tricks

Step 1: use key I and select LocRotScale, see below:

sprite 0031

Use the keys R and Z , type 90. This will rotate the object with 90 around Z.

Step 2: change the pozition of frame to next frame, see image below to see where it is.

sprite 0032

Repeat all steps 1 and 2. The object will be rotate with 360 degres.

You will have 4 frame for each direction : 0 , 90 , 180 , 270 and 360.

sprite 004

Setup the animation render output like image show below:

sprite 0041

Resolution X=100 Y=100.

Frame Range: End Frame: 4.

Output image will be: PNG with RGBA.

The result of animation will be four images. This will be an isometric character sprite

Blender 2.5 – Indirect Lighting

I will present the technique of indirect light in Blender 3D.

What exactly is indirect light ?

Lighting is mixed from direct sources and indirect reflection.

Lighting provided by reflection usually from wall or celiling surfaces.

In daylighting, this means that the light coming from the sky or the sun is reflected on a surface.

In a way: the reflected light is called indirect light.

I’ll start with my example plan divided into four.

I selected the four squares in the center and we extruded as shown below:

indirect light image

You will need two materials with which to work.

One will be based and the other will apply the indirect light.

In the figure below, it shows how to add such material in the Material tab.

The base material I have called Base.

I added a material which we have called indirect-light.

This material is a blue color.

In the picture below you can see the two materials and rendering.

As you can see there is no effect of indirect lighting.

For this I will make some additional settings.

Look at the picture below. Indirect Lighting must be enabled in the World tab.

Here the effect of indirect light with some settings made make by me.

This is a short tutorial about setting indirect light.

Addons on Blender 2.5 – Installing an addon using Python

Start Blender 3D version 2.5 or higher.

At the top, choose File menu and then User Preferences … or press keys Ctrl+Alt+U

See the picture below:

A dialog will appear and you can select the script with that addon.

In this case his named

The script will be found in the User Preferences window on Camera Add-Ons section.

See image:

Let’s talk now about the script:

The source code does not have too many issues that can not be understood.

It is divided into three main parts: the first addon declaration, the second is to declare the two classes and a third room for registration.

The source code is not complete. It is made only for illustration.

It is good to read and on this wiki

The GUI result is show in next image.

I will return with a more complex tutorial on this topic.

Unwrapping a mesh under Blender 2.5

The Blender 2.5 has a number of options available to map the UVW coordinates of an object.

The “UVW map” is a result of process.

This result is essentially a set of co-ordinates use to tell them how a texture image is supposed to be applied over the surfaces of a model.

Go on UV Editing, select the object ( the cube in this case) and enter on Edit Mode.

All keys will be pressed with the mouse cursor in the area 3D View, where the object is edited.

Now if you press key U and select first option you will see this …

UVW map simple

… if you select Smart UV Project, you will see the second image.

UVW map smart project

The best approach is to use a systems of cuts, referred to as Seams, are specially marked edge elements.

See in next image , how unwrapping process knows to split and make the UVW map.

In this case. select some edges and press Ctr+E select option Mark Seam.

I select edges from a face , and result is this:

UVW map seam

This is just a simple example , you can find more options.
