I'm currently working on an online configurator with 3D preview. The kind of tool you often see for cars.
I need to render hundreds materials for small portion of image which are not rectangular.
Is there a way to speed up render ?
Solutions I see so far :
- give an image to be used as a mask, it would be usefull as a greyscale that define the number of samples we want, I fear this option does not exists and require to tweak the source code
- mask areas that does not require rendering with a 3D object on front of camera that use some kind of "black hole" matter that will be blazing fast to render, but I don't know how to create this matter.
Do you see any other ways to achieve this ?
