Blender Manual: Camera

LuxCoreRender Cameras

Header

All three camera types are supported. For details on the three camera types, see the Blender manual link at the top.

In LuxCore, these settings are changed or new:

Clipping

Camera clipping is optional in LuxCore. If disabled, the near clipping plane is set to 0 + a very small epsilon value and the far clipping plane is set to infinity.

Clipping Plane

LuxCore offers a clipping plane that can be used to clip the scene. The difference to the near and far clipping planes is only that the arbitrary clipping plane can be rotated. In BlendLuxCore, the location and rotation of the clipping plane is derived from a Blender object. It is best to use a plane mesh as clipping plane object to be able to get a preview of the clipping, but you are free to use any object you like. Only the location and rotation of the object are considered for the clipping plane, the scale does not matter.

Camera Volume

By default, the camera sends one ray through the middle of its film when the render is started and uses the volume on the hit surface as its exterior volume. This should result in the correct exterior volume in almost all well-formed scenes. However you can also disable this behaviour and manually select the exterior volume by disabling "Auto-Detect Camera Volume".

The camera volume specifies the starting volume of rays traced from the camera. If your camera is e.g. under water and you have a water volume in the scene, you should select the water volume as camera volume.

ImagePipeline

The image pipeline is LuxCore's built-in mini-compositor. It has only a few features compared to Blender's compositor, but it is quick to set up.

See ImagePipeline for a general description of the various plugins.

Note that some plugins are hidden in BlendLuxCore to improve the user-friendliness.

Depth of Field

See the Blender manual.

Note: The F-stop in the depth of field settings only affects the strength of the blurring. It does not change the image brightness, even with "Camera Settings" tonemapper enabled.

Use Autofocus: If this option is enabled, the camera will trace a ray through the middle of the film at render start and use the distance of the hit surface as the focus distance.

Motion Blur

Blender manual

Motion blur in BlendLuxCore should behave very similar to motion blur in Cycles. However Cycles offers a "position" setting with the options "Center on Frame", "End on Frame" and "Start on Frame". BlendLuxCore currently only supports the "Center on Frame" mode. This means that if you set the Shutter value to 2, the blur will start one frame before the current frame and end on the next frame.

If your objects move only in a straight line for the duration of the blur, you can leave the "Steps" setting on the default value of 2. However, if your objects move in a curved fashion, you will need to raise the "Steps" value, which will subdivide the motion. How many steps you need exactly depends on how far your objects' movement differs from a straight line and is best found through a few test renders.

LuxCore does not support rolling shutter emulation.
LuxCore also does not support deformation motion blur currently (version v2.0alpha7).
