Common settings - Deferred Z-buffer - Postprocessing

After modeling the static shapes and their subsequent animation, the render finally comes up with which we get the final appearance of the scene. To render, click the Render button on the toolbar or use keyboard shortcut F10.

Common settings

After clicking the Render button, the Render settings window will show up first. The first set of parameters here is for setting render output. The output can be rendered in total in three types. The first one is Current frame - which only renders the frame that currently holds the animation position. If you leave the Save path field blank, this option also renders the preview, which is not saved anywhere, and is lost after closing the window.

The other two types Frame sequence and Video basically have a lot in common. As their names suggest, in the first case the animation is rendered as a series of separate images in each file to the selected location on the disc according to Save path. In the second case the animation is saved to a video file using a video compressor that uses fourCC code to identify itself. In the Animation section below, there are two fields From and To that allow you to set the animation section from which the image is to be rendered. However, this happens only when the Part radiobutton is switched. In the case of an active Whole radiobutton, the animation will be rendered in its entirety regardless of the From, To values.

Once the parameters for file output are set, the rendering process will, of course, be started by pressing the Render button.

The Animation section also contains the Number of digits field. When rendering a frame sequence, we may need to store images with a specific numbering range. With the Number of digits field, we can set the fixed number of digits in the file name of each stored image, including leading zeros. Attention however, all saved files are numbered by frame number. For example, if you want to save frames from 20th to 50th, they will have 20 to 50 numbers. The sequence frame file name is assembled as the contents of the File name + number from interval From To + suffix field Bitmap format.

Tip: Also, the Bitmap format and Video format parameters are included in the data output section. You can set them at the same time, but the Bitmap format option is only used when rendering Current frame or Frame sequence. On the contrary, Video format will only be used for Video rendering.

Deferred Z-buffer

Further parameters in the render settings window apply to effects used directly in 3D model space. CaZaBa uses the Deferred shading method. This means that the scene is being processed sequentially for each model, and also for each effect you use. On the one hand, it is required by a hardware-intensive effects that prevents all effects from being processed by one video card call, but it also offers two advantages for user work.

The first advantage is that each effect can be turned on or off separately, and you can independently control some of its parameters. In practice, this means that, if necessary, the user can render the scene for example without diffuse lighting or, on the other hand, set up the wireframe rendering, etc.

The second advantage is that the above mentioned turning on / off of individual effects is not limited to overall render only, but can also be set to render properties of individual models. For this, you only need to leave the render settings window and move to model properties. You open it by selecting Model - Model Properties... or Ctrl + P. There is a list of models in the currently edited animation on the left, and the checkboxes for each effect on the right. Thanks to them, for example, one model can ommit casting or receiving shadows, while other models will continue to cast shadows.

Tip: In general, most of the graphic effects are dependent on light sources. With the placement of light sources (the Cameras / Lights tab on the left panel) into the scene, the render will respond in a standard way. However, if no light source is present then is used only the basic source at the point of viewports camera and some effects will not be processed.

Tip: Render is always done from the viewpoint of one of the four viewports. To render a view from the camera in the space, proceed as follows. On the Cameras / Lights tab of the left panel, create Camera and place it in the space you want. Then in any viewport click the down arrow in the upper left corner and select View - Camera... Select your camera in the list and press OK. You immediately see that the viewport renders the view of the camera. This viewport then select for rendering on the Source drop-down menu in the render settings window.


The Postprocesses section applies to the effects that will be used to edit the entire image that we receive after processing individual objects in the scene. It is more about perfecting the picture. However, at this processing stage, render also has a diffuse image, its depth map and map of all shining objects in the image. This makes it possible to easily and efficiently hit the resulting form and significantly increase its value with the effects present.
