This page provides information about camera parameters in Chaos Envision.

Overview

The camera parameters are accessible in the Details tab when a camera is selected. Cameras can be selected in the Camera tab as well as in the Cameras filter tab of the Objects tab.

Parameters

	A field for the name of the selected camera. You can rename the camera. The new name is automatically displayed in the respective Objects filter tab.
	Lock – Disables the camera transformation options (position and rotation). The options become greyed out. Click to enable the options for manipulation again.
	Select hierarchy All – Selects the parent element and all children of the current selection from within the scene hierarchy.
	Select hierarchy Parent only – Selects only the parent of the current selection from within the scene hierarchy.
	Select hierarchy All children – Selects the rest of the children in the scene hierarchy group the current selection belongs to.
	Duplicate Camera – Duplicates the selected camera.
	Copy Camera Settings – Copies all settings of the selected camera.
	Paste Camera Settings – Pastes the previously copied camera settings to the selected camera.
	Move along spline – Associates the selected camera with a spline to define its direction of movement.
	Move along spline settings – Opens the Move along spline settings. Available when the Move along spline button is activated and a spline is selected.
	Look at – Picks an object the selected camera should look at during animation.

Transformations

Position – Moves the camera along the X, Y and Z axes.

Rotation – Rotates the camera along the X, Y and Z axes.

Click to restore all position and rotation values to their default values, i.e to zero.

Move Along Spline

Speed – Specifies the speed of the camera while moving along the spline.

Offset – Specifies the camera forward offset from the starting point of the spline.

Animation – Specifies the behavior of the animation after being played. It can loop, stop, hide, or extrapolate.

Follow Spline – When enabled, the camera aligns with the centerline of the spline, automatically following its path and maintaining the same direction as the spline.

General

Base properties

Camera Type – Specifies the type of camera. Currently, only the Perspective type is available.

Aspect Ratio – Sets the aspect of the render resolution.

Simplify Aspect Ratio () – Simplifies the aspect ratio. For example, if the resolution is 1920x1080 pixels, clicking the Simplify Aspect Ratio button sets it to 16x9.

Mode

– Switches to the use of Field of View.

– Switches to the use of Focal Length.

View Angle – Specifies the angle of view that the camera captures. Narrow angles zoom in, wider angles zoom out.

Focal Length – Specifies the focal length of the camera in mm. Longer focal lengths have narrower view angle and result in zoom in. Shorter focal lengths have wider view angle and result in zoom out.

Exposure

Auto – Calculates the camera exposure and white balance automatically.

Exposure – Controls the amount of light entering the camera, which impacts the image brightness. Higher values let less light in and result in a darker image. Lower values brighten the image.

– (Pick Surface) Sets exposure compensation based on the brightness of a picked surface.

White balance – Allows additional modification of the image to compensate for the "color temperature" of a light source, which refers to the relative warmth or coolness of white light. Objects in the scene that have the specified color appear white in the image.

Depth of Field

Depth of field – Enables the depth of field effect, which controls which areas of the image are in or out of focus.

Aperture – Specifies the width of the camera aperture in millimeters. This controls how blurred objects out of the focal distance appear. Lower values result in more blurred objects.

Focal Distance – Specifies the distance from the camera where objects appear in sharp focus. The rest of the objects are blurred based on the Aperture F-Stop value.

– (Pick Focal Point) Determines the focal distance based on a point picked in the view.

Tilt correction (two-point perspective)

Automatic Vertical Tilt – When enabled, automatically tilts the camera, straightening all vertical lines to simulate 2-point perspective.

When a camera is placed and selected in the Animation Timeline, a keyframe button appears for the Aperture, Focal Distance, and Exposure parameters, allowing them to be animated.

Color Corrections

Exposure Corrections

Highlight burn – Applies exposure corrections to highlights in the image. This option is hidden when Filmic tonemap is on.

Contrast – Positive values push the colors away from the medium gray value to increase image contrast. Negative values push the colors closer to medium grey.

Filmic Tonemap

Filmic tonemap – Color corrects the image to simulate the look of camera film. It applies a tone mapping curve that produces crisper shadows and softer transition to overexposed highlights, while keeping the midtones.

Filmic type – Specifies the type of curves used for the tone mapping. You can choose between Hable and AMPAS.

Hable – Uses a parametric curve, based on the formula of John Hable, that gives a few intuitive controls over the shadows, mids and highlights.

Ampas – Approximates the Academy of Motion Picture Arts and Sciences filmic curve from the ACES color encoding system. It resembles traditional film image rendering with an S-shaped curve.

Gamma – Specifies the gamma correction. It is applied before the operator.

Shoulder strength – Determines the softness of the mid to highlight transition. Higher values start the transition earlier and affect more of the mid tones. This results in an overall brighter image and less burned highlights.

Linear strength – Determines the strength of the effect from changing Linear angle.

Linear angle – Determines the angle of the curve at the base. Higher values brighten the shadows and mids, while lower values darken the shadows.

Toe strength – Determines how crisp the shadows are. Higher values darken the low and mid tones, increasing the contrast.

White point – The image intensity, which gets mapped to 1 in the curve. This parameter scales the whole curve evenly.

LUT

LUT – Applies a lookup table file to the scene.

Amount – Specifies the LUT weight, where 0 is no LUT effect and a value of 1.0 applies fully the effect.

Load – Loads a LUT (lookup table) file.

Color space – Specifies the color space for the loaded LUT file.

Linear – The loaded LUT file is interpreted in linear color space.

sRGB – The loaded LUT file is interpreted in sRGB color space.

V-Ray Log – The loaded LUT file is interpreted in a V-Ray logarithmic color space.

Bloom

Bloom – Applies bloom to the scene.

Intensity – Multiplier for the bloom source. Increasing the value can boost the effect.

Threshold – Sets a minimum value for the rendered pixels to be considered as lens effects source. The Bloom is generated only regarding pixels with larger value than the specified threshold.

Iterations (spread) – Specifies the size of the bloom spread. Larger values increase the spread but impact performance.

Hue/Saturation

Hue/Saturation – Applies HSL transformation on the image colors.

Hue – Changes the overall hue of the image colors (grey colors remain intact).

Saturation – Specifies the image colors' intensities. Positive values produce a more vibrant, saturated image while negative values desaturate and dull the image colors.

Lightness – Adds or removes white from the image. Positive values add white to the image, making it lighter. Negative values remove white from the image, making it darker.
