How to combine different render

[DrakeOnLand]

I have created a scene in daz . Which have a female,male and room as background. The render time was quite high due to low specifications system. So, i have separate female , male and background render . My question is this how to combine them in on pictures without losing picture quality ?

If you follow the renpy

You must be registered to see the links

it will explain you how to use sprites + backgrounds separately.

If the male and female are supposed to be together, you can just merge them as a single sprite with any image editing software.
