The material of the trails. All trails with the same material will dynamically batch.
The color of a Playground Trail is done with a Gradient. The far left is the start time/point and the far right is the end time/point. The Gradient will be iterated through based on which Color Mode is set.
The Color Mode determines if colors from the Gradient should be picked by the points Lifetime value or the normalized point index in the Point Array. Using Point Array can come in handy if you for example only want two points drawing a straight line, where you want a start- and end color only.
Point Array Alpha
When Color Mode is set to Lifetime the alpha can be set from a normalized Animation Curve.
The Uv Mode determines if mesh UVs should be set by the Lifetime value or the normalized point index in the Point Array. Using Lifetime will make the UVs move over time where Point Array will make them stretch over the available points in the array.
The Render Mode determines what perspective the trail is rendered.
Billboard – Perspective is set towards the assigned Billboard Transform.
Horizontal – Render the trail flat on XZ axis.
Vertical – Render the trail flat on XY axis.
Custom Render Scale – Perspective is set towards a custom scaled normal.
