Post Effect
Post effects are visual effects that you can apply to the whole screen. Lens Studio has a number of such built in effects that you can easily add and modify. Because Color Correction is by far the most commonly used Post Effect, this guide is broken out into two sections: the Color Correction Post Effect and all of the other Post Effects.
Color Correction Post Effect
The Color Correction Post Effect uses an input color lookup table image to adjust the coloring of the Lenses. Image adjustments (saturation, exposure, color balance, etc.) are performed in an external editor like Photoshop and applied to the lookup table. The lookup table is then imported into Lens Studio and added to a Color Correction Post Effect object.
To create a Color Correction Post Effect object, press the "+" button in the Objects
panel. Then, select Color Correction
and pick one of the built in textures
You can also tune the intensity of the Post Effect
with the Alpha
slider in the Inspector
panel.
Tip Make sure your Color Correction Post Effect object is listed below everything you want to colorize in the Objects
panel.
Lens Studio includes a number of built-in Color Correction textures if you are unable to create your own. They can be added to your project in the Objects
panel by selecting + -> Color Correction
.
Download the Color Correction Lookup Table
To make your own custom Color Correction Post Effect, download the below base lookup table. You'll be making your modifications to this image.
Download the Base Lookup Table
You can also get this texture by going to the Resources Panel -> + -> Color Correction Texture -> Empty
.
Modify the Color Correction Lookup Table
Open the base lookup table image in Photoshop or a similar image editing tool. You'll be making your adjustments to this lookup image. Add a reference photo as a layer above the lookup layer. Then, add adjustment layers above both the reference and the lookup. In the example below, we've added simple Hue/Saturation
and Color Balance
adjustment layers to give the Lenses a pink tone.
Use your reference layer and the added adjustment layers to tune your effect.
Before export, hide the reference layer. Your adjustment layers will apply to the still visible image lookup table.
Export the lookup image with your newly added adjustments as a PNG.
Add your adjusted lookup table texture to your project by dragging it to the Resources
panel. Then, in the Objects
panel, select your newly added Post Effect
object and set its Main Texture
to the adjusted lookup table texture in the Inspector
panel. You should now see your image adjustments applied to your Lenses.
The Color Correction Post Effect object only supports a non-compressed PNG. Compressing the PNG or using a JPG will result in noticeable artifacts.

Adjusting the Post Effect
Post Effects have various parameters that you can adjust in the Inspector

panel.
With the corresponding material selected in the Resources
panel, you're able to adjust its settings in the Inspector
panel.
