[Shaders updated on 2009.05.18 - please download again- lots of improvements!]
[Slide](http://slidelondon.com) have just released a new tool for public consumption. It's a mental ray shader - slideElements - which lets you easily save multiple 3dsmax render elements to a single OpenEXR file for use in your compositing package of choice. Download the SlideShaders package from [here](http://slidelondon.com/iv). Installation and usage instructions are somewhere in the zip. It's built for 3dsmax2009 in both 32 and 64-bit flavours. The package includes the mrGeomShaderObject 3dsmax plugin and the Microsoft Visual Studio 2008 redists, which you will probably need to install to get the shaders to work. It should also work fine in 3dsmax 2010 (although this is not fully tested yet).
Please post any problems or questions to this thread - I’ll do my best to get you up and running with it.
Massive props to [Puppet](http://www.puppet.tfdv.com/download/shaders_p_e.shtml) for releasing the source to his shaders, without which slideElements would not exist. Thank you so much for helping the community like this. To follow suit, we have also released a version of the archive with full source and Visual Studio 2008 project, also at the link above. Cheers!
