# Scene Presets

Scene Presets allows you to set a few variables so those settings are applied.

From Menu > Set Scene Presets

## Scale Multiplier

Sets the strand 'scale' multiplier. This is the scale value that all strand will be multiplied by (by 2) when created.

## Curve Width

Changes the curve width display thickness

## Aim Mode On Create

Default is set to Aim Mode, you can switch this to Auto Normal if you prefer, the flipping/mirroring/UV Retaining System will adjust based on your Aim Mode automatically.

## Orient Sample Distance % (Card Only)

This is the percentage of the length starting from the 'root' of a strand curve to use as the reference point for the "Orient" function.

## Mirror/Flip UV Method (Card Only)

Determines how we want to handle the UVs when after we mirror or flip a strand. When a strand is mirrored or flipped, their UV are reversed (red). The tool offers options for you to automatically fix that. 

* Flip UV in U - If your UVs are always vertically laid out, this will be the best option. (fast)
* Flip UV in V - If your UVs are always horizontally laid out, this will be the best option. (fast)
* Retain UV - Automatically re-unwraps and remaps so it is in the correct position at all times. (can be slow if more strands are selected)
* None - Do not do anything to the UVs, leave them reversed.

## UV V-Axis Treatment (Card Only)

This setting controls how the inner vertical UVs is handled during unwrap.

* Respect CV Distance - It takes in account of the CV distances AND curvature of curves when unwrapping.
* Stretched Equally - Ignores the distance of CVs on profile curves and will always unitize and unfold into equally sized UV faces.
