Hello! I’m trying to import a tiled landscape from world machine into UE5. it’s 12x12 2017x2017 tiles, which on disk are around 4.2 GB. When I pick the 0x_0y tile, the entire engine crashes to desktop and leaves me with the following error:
Now, I am pretty sure this is an overflow of something because it’s talking about allocating over 18000 petabytes of data, which is multiple orders of magnitude off the scale I’m working at here. So I’m wondering if there is some engine memory allowance I need to tweak upwards, or something?
I should note that when attempting to import I get a brief spike of CPU activity on all cores, ram usage jumps about 2GB, and then it errors out. I still have over 16GB of ram free when that happens.
If anyone here has an idea, please let me know!
