# TweakAir

TweakAir is a variation of the Air renderer used to interactively rerender parts of a scene that have changed. This is done by placing mayaman in TweakAir mode with the toggle in the main menu and then previewing as per normal... after that you are free to change material values and re-preview, only the objects with modified shader parameters will be rerendere.

## Tips

Setup a hot-key to do the preview, the hotkey should call 'doMayaManRender(0)'.

When 'Only Render Selected Objects' is turned on only the shaders for selected objects are sent to tweakair, this can speed up interaction.

## Limitations

Shadow maps are not recomputed during tweaking, they are computed once during the initial render.

Turning ray-traced shadows on/off for a light only works if the light had ray-traced shadows on during the initial render otherwise the rib will not contain the correct ray-traced visibility flags.
