[BUG] Crashing on large area selection with Object + Terrain

[ereticor]

Describe the bug

Selecting the area slightly bigger than usual (as soon as you see "large are" warning) starts to eat up all of the RAM and then crashes at around 80%. Also brings down windows explorer due to all memory being eaten

Used bbox area
settings:

52.392154,30.897675,52.42671,30.971832 - this one works fine
52.344569,30.859222,52.496996,31.090622 - this one takes a lot more time and crashes

Arnis and Minecraft version
Arnis 2.4.1
Windows 11, 64Gb RAM/i9-13900HX

Screenshots

Additional context

• log empty
• memory usage goes around 58Gb and slowly eating up more, CPU around 5-10%

Is there a way to limit the max memory usage for this?

[ereticor]

tried with server, ate up to 96 gb at some point. Haven't had a chance to finish it but didn't break either

Thanks for the report! This should be fixed in the next release; I added a floodfill size cap and some memory optimizations for large areas. If you still see it after the update, please reopen with logs.

[ereticor]

@louis-e does it mean the would be a hard memory cap? Or is it planned to be dynamic with ability to change the values?

[louis-e]

It's a hardcoded limit, however it will not restrict your selected area size. It will just stop floodfilling single elements if they are too large (e.g. enormous water areas).

[ereticor]

@louis-e gotcha. Can you then include the short instruction on where to find this limit in code once its released? Im perfectly fine with using all the ram the server has if it makes the process a bit faster
