RTTassist

About:

RTTassist is a free MaxScript toolset shaped in a beautiful interface that automates the tedious process of texture baking. It has a wide range of features, but most especially it is designed to give you better user experience! Take a look at some of its main features (to see them in action check the site or the youtube channel):

* Explode all objects using an unique vector so there are no overlapping objects and there is enough space between them.            

* Produce the best quality, normal, Ambient Occlusion and other map types.

* Render using "Smart" , an algorithm that saves rendering time by processing less important objects more quickly.

* Render using the "Isolation" method.

* Batch render multiple files at once.

* Combine all rendered maps together in a single resulting map.

* Create a custom render presets for every need.

* Easy to use interface and "click-of-a-button" workflow.

* LiveLog - Instant visual feedback at every step.

Version 1.4 for Max 9

Version 1.6 is available

* Import/Export of projection cage meshes(Use Ctrl + MMB on the Project button). 10x to Joshua Stubbles for the idea.
* New BuildPairs feature that uses the name you can enter in the new BuildPairs Name Field.
* Users can now create a default preset for mray in case they use the built in automatic switch between scanline and mray.For additional information check the help documentation.
* New HideFaces(MR) checkbox is added that allows you to hide the faces of all low-poly objects when rendering.

The new build pairs explained

RMB + Click] = on the BuildPairs button will rename the selected objects by using the text entered in the build pairs text field (located right next to the Build Pairs button). Thisway you have more control over the names of the objects. Check out the help documentation for more in depth information.

 *Revamped baking system from ToTex. Special thanks to Sven Fraeys

 *Hides all faces of low poly objects when MentalRay is used for texture baking.
 *Projection List now shows the number of objects each Low-Poly has in its reference geometry list.

Note:

Download version 1.5 from official site of RTTAssist.

Version 1.4 is available.
 The addition to the new version is that now RTTassist can render at once different groups of objects on separate texture maps. All you need to do is to put your objects in different selection sets and when you are ready to render, first click on the "Sel. Set" checkbox located in the Preset Manager drop down menu (a new dialog will pop up asking you to choose exactly which selection sets do you want to render) and then hit the Render button using RMB. 

Also installing the max9 version should execute without problems.

RTTassist version 1.3. is available!

Here is the changelog:
      * new projection spinner is added.
      * saving the scene will no longer store the objects in their exploded state.(Objects will implode on save and will be exploded    back once the save operation is complete.)
       * Combined maps now include properly rendered alpha channel (thanks to DaveWortley and denisT)
       * The issues with the installer are fixed (@Norman3D, @renderhjs, 10x a lot for the tips! )
The new projection spinner explained

LMB + Click = on the spinner arrows will increase or decrease the cage size of all objects by 0,01 step. You can enter an amount directly in the spinner by typing it in.
