The single object visualization most often is performed on a clear white background. It is difficult to achieve this through the common configuring the scene – increasing the illumination of the scene “lights up” the object, decreasing – the background becomes gray instead of white. If the object itself can be simply rendered on a transparent background and then imposed on white, but what about its reflections?
Let’s consider the way how we can render the object and its reflection on a white background.
State switches so-called “radio buttons” are used in the case to limit the choice by one value from several available ones. There are a lot of such buttons in the Blender interface, for example, switching between RGB and BW rendering modes or setting the texture mapping mode. Such buttons can be created in the Blender add-ons interface too.
Every 3D-artist knows that the workplace is always less. The larger monitor, the larger available workspace on it – the work is more convenient and faster. Blender allows winning some extra space on the screen, hiding the window title, which is still not useful.
The key combination:
alt + F11
allows to hide the Blender window title and expand the work area to the entire monitor. Pressing this key combination again returns Blender to its original state.
During the image rendering in Blender, it is impossible to do anything else, the computer is strong “brakes”. Blender takes all available computing power without leaving almost nothing to other applications.
In order to run render in Blender with a low priority, so that it does not fill the entire computer and is guaranteed not to slow down the other programs work, you need:
/LOW – means that Blender will be launched with the lowest priority, computing power will be allocated to it after the all other programs.
/MIN – the window will be minimized in the taskbar.
/B – no separate window for launching Blender.
/D _path_to_blender_directory_ – here you need to specify the path to the directory where Blender is installed. Since usually all programs are installed in the “Program Files” or “Program Files (x86)” directories (there are spaces in the directory name), you need to enclose it in quotation marks.
_full_path_to_blender_ – specify here the full path to the blender.exe file. Enclose it in quotation marks by the same rules.
-b – Blender background launch (no graphical interface is created).
_path_to_blend_file_ – the full path to the project you need to render. If there are spaces in the path, it must also be enclosed in quotation marks.
-f X – instead of X, you need to specify the number of the frame you need to render.
-t X1 – instead of X1 you need to specify the number of processor cores that would be allocated for rendering. It is worth to allocate the half of the available cores.
-n 20 – means that Blender will be launched with the lowest priority, computing power will be allocated to it after the all other programs.
-b – Blender background launch (no graphical interface is created).
_path_to_blend_file_ – the full path to the project you need to render.
-f X – instead of X, you need to specify the number of the frame you need to render.
-t X1 – instead of X1 you need to specify the number of processor cores that would be allocated for rendering. It is worth to allocate the half of the available cores.
