Hi,
I'm Northgard technical director.
We are creating buffers to draw various 2D shapes into textures for map generation. Then we download the textures from GPU to CPU for additional processing. These textures are then used to generate the landscape. For some reason unknown to us the textures generated in some case appears to be corrupted, resulting in these weird height maps. We haven't been able to investigate the issue in details atm.
If you could capture a trace of the issue in renderdoc or apitrace [1] upload it somewhere and provide the link we might be able to investigate it. But currently I can't get a trace because the HashLink virtual machine crashes. Maybe you guys could try compiling with HL/C and try grabbing a trace with the binary?
