World map tile size calculation formula confusion

It is component size * components in one axis + 1.

so for example, for the 8192 resolution it is 254 * 32 + 1 = 8192

There may be other size combinations possible by using different numbers of quads per section and sections per component. The quickest way to try a bunch of values is to use the new landscape tool and try changing the values and see what it gives as a valid resolution.

Unfortunately the page lists the value as 8129 rather than 8192. … and I just entered your numbers and formula into my regular hand-held calculator and it comes out as … 8129! I knew about the “+1” modifier, and after removing it the resulting value, 8128, factored into 24064, 42032, 81016, 16508, 32254, and 64127. In the article we see

These examples focus on square Landscapes. However, you can create Landscapes that are not square. For instance, in the first example the 10x10 is not special. Assuming 63 quads per component, you could have any Landscape of AxB components with total size in vertices of (A63+1 , B63+1).

Which led me to suspect the “64” value as the case. (I admit I missed seeing that “245x254” item there in the table).

I’m currently creating an external utility that cleans up our map data and exports it into a format that Unreal is able to import. While the built-in Landscape calculator is certainly useful, it first has to have the data in a size and format that it can accept - which is what my tool is supposed to produce. Meaning I need to be able to use the formulas prior to their importation.
