光子图合并器 - VRay IRMap Merger

This script merges multiple *.vrmap files from a selected folder. Tested on Max 2012, Vray 2.0.

The benefit of rendering separate irradiance maps is that you can use distributed rendering. As with multi-frame incremental method, the map gets overwritten if multiple machines are being used.

这个工具用来合并VR的光子图，如果同一场景有多角度相机渲染，或是动画渲染的话，合并光子图就比较重要。可以把多个不同角度的光子图合并成一个总文件。

工具中会用到 imapviewer.exe 光子图查看器，这里提供的是VR3.03版本for max2014的光子查看器，应该是所有版本都通用的，如果不能用的话，可以手动将你自己版本的光子查看器拷到本工具的素材目录313文件夹下覆盖自带的，光子查看器一般是在：C:\Program Files\Chaos Group\V-Ray\3dsmax 2014 for x64\tools 里面，叫 imapviewer.exe。或者在开始 - 程序 - Chaos Group 里面也可以找到。

If you have a different version of Max and/or your VRay installation directory is other than the default one, please follow the instructions inside this script. The only thing you will have to change is the imapviewer.exe location folder. Any suggestions on how things could be improved are highly appreciated.
