Receptions work in Blender. Part 2

The preview does not need to render the entire working window.
When viewed from the camera in the preview, even that area of ​​the screen that does not get into the camera is rendered. This is an extra computer job.



You can set your own size of the render area by pressing Ctrl + B (Render Border) in the working window. Resize this area Ctrl + Alt + B.

When I saw for the first time that the material in Cycles not only shines itself, but also illuminates everything, I thought that the lamps as a class of objects are no longer needed. I was wrong.
In complex scenes, the light source (Lamp> Point) gives a quality much better than an object with a luminous material. Note that the light source has a size setting (next to the brightness setting).
')


Note the OpenEXR format
It allows you to save an image of 32 bits (usually 8 bits). With the help of Photoshop, you can return overexposed details. Open the rendered frame in Photoshop and translate it into 8 bits. When translating a dialog will appear in which you can adjust the brightness.



We cannot see at the same time the whole range of brightness that nature offers us. But the full range of brightness can be saved and corrected after the render.

Why is the Bevel modifier not working?
Because Bevel often enters the queue after the Edge Split modifier. At first, this is not obvious. It is necessary to change places.

You can animate almost any parameter or daw.
For example, it is necessary that the object in the first frame be, in the second one it disappears.



As a result, the animation of the disappearance of the cube. Please note - the disappearance in the working window, and not when rendering. For visibility when rendering is responsible camera icon.

You can animate and sliders:



Camera switching

• 0 (zero) (numeric keypad) - view from active camera
• Ctrl + 0 (zero) (numeric keypad) - view from the selected camera. Makes this selected camera main, i.e. active. You can also watch from objects and light sources.

Switch cameras in animation

• In the working window we create cameras and place them.
• In the timeline window, click M (Marker) and add markers where we want to switch cameras.
• We select the camera. Select a marker. In the timeline window, press Ctrl + B (Bind Camera to Markers) . We do this with every camera.

You should get something like this:



Application of materials based on their number
For example. There is a cap lamp table. Outside it is black, and inside it is white. And even the cap has the thickness of the metal.

• Model the outer shell
• Apply the modifier Solidify (Thickness)
• Create 3 materials: outer (black), inner (white), metal edge (blue)

Render farms that I use
RayPump - with one click the scene is sent to the network and the result is automatically downloaded. Every day, 80 conditional monetary units are given for which 3 pictures can actually be calculated for free. Quality limit of 200 samples. Resolution a maximum of 1280x720. The fact that I have an hour is considered there a couple of minutes. No watermark. Put a small logo renderdermy in the corner and does not spoil the image. You can put money and render without restrictions.

Sheepit-Renderfarm is a distributed free render farm. Everyone helps everyone. For helping others, a rating is calculated which determines the priority of your scenes in the queue.

How to set up automatic rendering of the scene on multiple machines?
Customize the scene:

• Assign the path to the folder rendered frames. It must be relative ie dancing from the scene folder, not from the root of the disk.
• Checkbox Overwrite uncheck - prohibit replacing already created frames.
• Checkbox Placeholders put - when the frame is taken into processing, a fake file is created simulating the created frame.

• Scene copy on each machine is not necessary. Open network access to the folder with the scene.
• Blender cannot open network folders with its own dialog. Open the scene through the operating system explorer and render.
• It happens for various external reasons that some frames are not calculated. Usually it is easy to sort these frames in Explorer by size in megabytes. Defective frames have a small size. You just have to throw them out and re-render the render, the machines themselves will fill the resulting gaps.
