I need advice on creating a historical map with provinces

I’m developing a grand strategy game, similar to Hearts of Iron 4, but with a chronological focus on the 13th century. The map is divided into administrative units for each nation to ensure gameplay diversity. However, I’m facing issues with the boundaries of these administrative units; they simply cannot connect properly.


In this case, I used SVG files of nations with administrative divisions that are publicly available, primarily from Wikipedia.

hello again.

are you importing them from blender? if you are, just import them with location and size properties.
issue seems to be with location and scaling. why not manually tweak their size and position anyways if the solution above isn’t viable?


Yes, I import maps from Blender. In the screenshot, I marked in red the Kingdom of Croatia and Slavonia, which was part of the Kingdom of Hungary in the SVG file. After that, I added the administrative units of Croatia and Slavonia and now I am working on their connection with the administrative units of Hungary, so that later I can correctly use the administrative structures of Austria-Hungary of the 19th century.

I’m not much of a builder or modeler, but set RenderFidelity to Precise on the meshes in Roblox and see what happens.

I set the value to “Precise”. All the same.

assuming each area is a separate mesh, then just insert each with location through the asset manager:

Everything is loading fine for me. The whole Kingdom of Hungary and the Kingdom of Croatia and Slovenia with their correct positions, that is, like this:

But I need to connect these separated two to make sure that I can attach the other administrative units surrounding these two to them:

if the borders match up perfectly according to the meshes from the map data you got, then just position and scale them to match up. it’s just a matter of being precise.

Then what is the best way to adjust the size to connect these two parts?

literally as manual as it can get. just resize, position, zoom in, and repeat until they look connected enough.

It’s going to be quite a long time. I’ve already tried it. Therefore, is there any other way to connect the borders?

no not that i know of. this seems to be a pretty specific scenario so i doubt much resources exist for these situations except tiresome, cumbersome, gruesome, and manual unpaid labor.

Is there any way I can create anchor points for both territories to connect the borders using anchor points?

More precisely, they already exist, but they are not enough to properly connect these boundaries. So how can I create more of these anchor points? And how to snap one anchor point to another anchor point of another 3D model?

this wouldn’t work in so many ways, i mean even if you do snap to these “anchor points” as you say, (i’ll assume you mean the origins) you’ll still need to scale them. it’s as simple as taking the 2 seperate parts and select every section in them to scale all of them at once.

well ofc it’s not going to fit if the borders are wrong. like imagine asking how could I connect france and malaysia, not possible.

Have you tried the snap tool in blender?
