Display Tab

The Display tab is a very important area where you can manipulate your rendered image (especially in terms of exposure/brightness, color saturation, and contrast) and apply other post‐processing effects.


Adjust Exposure: Automatically adjusts the rendered image's exposure.
Tonemapping: Select a tonemapping method: Standard, Filmic, Reinhard Global, Reinhard Local.
ISO: Defines how sensitive the image sensor is to the amount of light present. A value of 100 is mostly used for exterior shots under a clear sky and sun lighting. Higher values, usually between 400–1600 are used mostly for interior shots.
Shutter: The shutter speed corresponds to the duration a camera shutter stays open, measured in 1/sec. Low values result in brighter images.
f-number: The lens aperture is the ratio of the focal length to the effective aperture diameter. Low values make the image brighter.
Gamma: The gamma factor typically ranges from 1.0 to 2.5. In order to compensate for the darkening of the image due to non-linear output, we apply a gamma correction scheme to the pixel values before displaying the image.
Brightness: This parameter is used to compensate for a linear scaling of the image by a monitor.

Camera Response Function

Camera Response Function files use real data provided by the camera manufacturers to create realistic (non-linear) display results, as if the image were taken with that specific camera.


Sharpness: This is the most important option for controlling filtering during downsampling of the image. It is advised to use the default of 50%, which is a balanced value between blurring and sharpening. A value near 0% produces a more blurred image, while a value near 100% produces a more sharpened image.
Burn: The burn value can be used to compress a High Dynamic Range (HDR) into a Low Dynamic Range (LDR) image, presentable on screens and other limited range devices. Setting burn to 100% means that there is no compression.
Vignetting: In photography and optics, vignetting is a reduction of an image's brightness or saturation at the periphery compared to the image center.
Chroma: Increase the value to enhance the colors of the image. Chroma acts as a saturation control.
Contrast: Determines the difference in the color and brightness of the object and the objects within the same field of view. 0% equals a disabled control. 100% is the maximum value that can be set.
White Balance (K): Change the overall color balance of a render, so that it matches the expected physical phenomenon. A value of 6500K is usually used to balance sunlight and make white walls appear white, even if the sunlight is yellowish.
Glare: Glare is the effect of a high amount of protons arriving at a film, causing lighting to also flood nearby areas. The shape of the glare itself depends on the shape of the diaphragm.
Glare Type: Select how many blades you want. Radial equals Bloom.
Glare Weight: Controls the intensity of the glare.
Glare Radius: Controls the length of the blades.

Optix Denoiser

Optix offers AI-accelerated denoising. The denoiser can be enabled before or after the rendering has finished. If you enable Optix before starting the engine, two additional channels are enabled to ensure the best denoising quality. These channels are Normals and Raw Diffuse Color. An NVIDIA GPU is required for Optix to work.
Blend with original: Controls the blending between the original and the denoised image.


The Display tab is a very important area where you can manipulate your rendered image (especially in terms of exposure/brightness, color saturation, and contrast) and apply other post‐processing effects.

The Adjust Exposure option automatically adjusts the display settings to find the appropriate exposure based on the given image. You can see the effects of this option on an underexposed and overexposed image in the following images.

Presets are also available by clicking on the hamburger icon. The presets should be used as a guide to correctly adjust the intensity of the lights in the scene and avoid using unrealistic values. The available options are:

  • Exposure: Interior
  • Exposure: Interior Sunlight
  • Exposure: Exterior
