Some shader effect may also have additional properties that can be adjusted.
NOTE: Any change to a shader will be evident immediately when the asset is in preview and even when playing in program. This means you can make changes on the fly without having to stop.
Borders can provide a pleasing aesthetic for PIP type layers, effectively framing the asset with a color of choice.
Width: Use this to adjust the thickness of the border. The value is in pixels and ranges between 0 and 100.
Radius: This can be used to round the corners of the border. Since the effect also includes an alpha mask that clips the contents, increasing the amount can be used to provide a vignetting of the asset. In most cases the asset’s aspect ratio is more rectangular so this clipping clip will appear more as an oval shape. However, if you combine it with some geometry crop adjustments you can achieve a perfect circle.
Color: Click the Choose Color to select the desired color of the border itself.
A desire to blur an asset my seem unlikely but when used on underlying layers it can create an interesting bokeh (depth of field) effect making layers appear as if in a 3D space.
Amount: Simply the percentage between 0 and 50% of applied effect.
