“The secrets of Swimsuit babe ” by CGriders
There’re two scene files, character (babe.mb) and hair (babe-shave.mb), to render and they share the same command line (under :RENDER) with different options as variables. Different passes are put into different render layers which are indicated in the %layers% variable. There’re also mel scripts (eg. renderHighQuality.mel) which update the sampling attributes (eg. render settings, area lights) to control the quality of the output image. The scene file for the background is not included in this batch file. The total render time of all layers is about 3 hours with sample level min=0, max=2. It takes 5 hours to render if sample level min=1, max=3 without noticeable improvement in image quality.
5 Epilog
I think I’ve achieved my objective within the limitation I’ve got: amount of physical memory, number of computers, level of skill. If I’ve got more memory, I can do more in ZBrush. I have only got 1.5 million polygons with the 1.5GB of RAM I’ve got. This is not enough for this full body character. That’s why I gave up displacement map in the end as I didn’t want to separate it into several pieces. If I’ve got a couple of computers, I can break up the image into several pieces and render them simultaneously so that I can do more tests especially when displacement map is applied and when the shader is too slow like p_MegaTK.
Finally, I think I’ll make another image of her and I’ll give her a name next time.
