Blender :Details of Render layer node

October 25th, 2011 Remo No comments

This node is very useful for creating the /composing the 3D scene with a 2D background or may be useful when creating a video footage for the blender.

3d objects are being shown using this node, this node o also shows the image which has been set up at the background., this also enables the back buffer.

What are the compositing sockets in the render layer node ?

Lets see it in details:

Z: distance from the camera (away direction)in the blender usints.

Normal(NOR):when the lights are coming from the sight then how color is affected.

UV: How the image is distorted by the mapped mapping of the UV.

Speed(Vec):This is for the speed of moving object ,it mainly for fast moving object and at which direction the object is moving.

Color(Col):This is for the RGB value s of the color of an image.

Diffuse: The softening c of colors as they diffuse through the m materials

Specular: how the colors will shine when they are added or exposed to the light

Shadow: This is for objects on another object because one object create shadow on another object .

AO: This gives the effect of ambient occlusion on the colors

Reflect(Ref):This is an object and the type of the object are mirror type. This mirror type objects show colors by reflection. This is not the part of the color of the basic material.

Refract: This is the bending of colors when they are passed through objects which are transparent.

Radio(Radiosity):Objects can emit the colors and cast onto the scene.

Index of each object have some numeric ordinal(index) o in the scene when seen by camera.

Creating animations using the best free software named blender

what is blender ??

So Blender is an open source projects for the creating creation of 3D movies ,games and many animation etc,.

All are done by the use of blender.

So when you are using the blender you feel just like many other popular soft wares which are very expensive like MAYA etc but in blender all is free. This is a open source project and you can get it at free of cost and can also use it for your own purpose.

I will now discuss the composing in blender.

What is composing in blender or how composing is done in blender is as follows.

Several images when combined into a single image called composing. An artist may want to combine a 3D element to 2D element .Including the background etc.

In this scenario blender may l help a lot.

How do we compose in blender in blender ??

In blender 2.45

NOW we will discuss the node window in blender.

So what is node window or node editor??

To access the node editor use SHIFT+F3

What are the optional socekets name in the blender ??

There are a few sockets av available to work wi with , they are Alpha socket ,Image socketr,Z socket.

How to enable buttons in a under RENDER Layer menu .

First need to know how to access the render layer menu .

Press F10 key to get the Render Layer menu.
