SteamRoller

Version: 
v1.72
Date Updated: 
10/05/2018

Steamroller unwraps every objects in a selection using Max's built-in flatten function based on the specified parameters. Steamroller is mainly intended as a quick and dirty method of quickly unwrapping lightmap UVs on large sets of objects, similar to the automatic unwrap in Render to Texture.

To install, run the macroscript (.mcr) or drag the file into the viewport, then go to Customize > Customize User Interface. On the toolbars tab, select "# SmallpolyScripts" from the category and drag Steamroller onto a toolbar to create a button.

- UV tools now closes with steamroller
- UV tools now moves with steamroller (currently, as a fixed position)
- Added UV channel suffixes to allow unwrapping to multiple channels.

- Hunting down a bug that is causing unwraps to fail when "by selection" is disabled.
v1.3 - 2018.02.07
- Bugfix for a case where some of the geometry wouldn't be unwrapped.
v1.2 - 2018.02.06
- Fixed the instance problem by using a custom unwrapper name and checking for it.
- The applied modifier is now called "SteamRoller_UVW"
- The modifier has also opened up an easy way to clear the unwrappers and check for them before flattening.
v1.1 - 2018.02.02 - Working on instance fix. Making script category consistent. May be doing some fixes soon.
