Region Rendering with Maya
Region rendering is a useful option to use when rendering large, single frame images. This process has not yet been automated but can be done quickly and easily using the "Extra Parameters" Field when launching your job. Below is a quick example of how to split your image into 10 separate regions. Please note that this process will start separate render jobs for each region and you (the customer) will need some sort of image editing software to combine the regions into the final full size image...
Take note of what the final resolution is to be. For this example, our final completed image will be 6200x6200 px. Depending on the complexity of the image you will need to decide how many regions you want. For this example we are going to use 10 regions.
Launching the Renders:
Begin by launching the job in a normal fashion; to make things easier you may want to rename the job slightly, for example "Scene_Reg_1", "Scene_Reg_2", "Scene_Reg_3", etc.
For each region submitted you will add in the follow string to the "Extra Parameters" field, modifying the string slightly for each submission.
-reg 0 6200 0 620
This line tells Maya to only render the bottom region of the image. "6200 pixels from the bottom left and 620 pixels up from the bottom" For each subsequent submission you will use the same method and adjust the above string.
-reg 0 6200 620 1240
This tells Maya to render "6200 pixels from left to right, and the portion of the image starting from 620 pixels up to 1240 pixels up"
Once all regions have completed rendering, you can open them in Photoshop. All the images will be the correct full size, with only the region rendered. So you can just overlay all regions and save the document.
Note: To Find the regions, just divide the height of the image by the number of regions you want. For the above example its height was 6200. We divide 6200 / 10, giving us 620. We start at 0 and continuously add 620 pixels...
0 + 620 = 620 620 + 620 = 1240 1240 + 620 = 1860 and so on...
These parameters can be modified to render as many or as few regions as you would like, depending on the size and complexity of the image.
