I'm interested in WorldMachine to build a 300x300km (to start) terrain.  From reading through the forums, I found mention that some of the features of World Machine are limited to 250km sizes.  If this is still the case, what features have this limitation?  Thank you for your help.


Hi there,

I'm not aware of any limitation. You can go to the Project Settings -> World Extents and set it to a larger value.

Testing that size right now, there's a few glitches relating to a couple of the views (leftside and 3d view), but no problem creating or exporting, and the layout view has no problem at that size.

That's great news, three more questions.   :o

I'm running a quad-core hyperthreaded processor with 8GB of RAM.  I'm thinking I want to output a RAW-FP32 heightmap plus deposition map, wear map and flow map as 8-bit RAW.  At 2.5m resolution that's about 100.8GB of data.  Do you think it will run in my lifetime?  Will I have memory problems?  Are there any specific features that dramatically increase memory use?
