How would I effectively and quickly render images of my map?

Hello,

I am working on a type of driving game where you can work as many roles.
And I have the fundamentals down but I am having issues surrounding the minimap.

How would I effectively and quickly take a render of my map in order to use it in in a minimap.
To clarify, I have used RoRender however my map is too big leading to the minimap being blurry because I have to zoom in.

I have thought about splitting the map into 1024x1024 sections where I can render but the problem is the sheer amount of time it would take. Estimately It would take 34 hours of straight rendering to complete.

So simply, I need a way to quickly generate high resolution images of the entire map and then stitch them together into the minimap.

I have seen some posts about this but they don’t really fit into what I want to achieve.

Thanks in advance.

not sure but use viewport frames?

Viewport Frames do not replicate Roblox Terrain and it would be too performance heavy due to the size of my map.

That is why I am resorting to rendered images of the map which I would then be able to stitch together.
