I'm trying to export orthomosaic of large project, but get OOM(out-of-memory) at the end of export orthomosaic, as I can see memory consumption start grow drastically when 99% is done. I'm able successfully build orthomosaic from mesh builded from sparse point cloud and I'm export it in Google Map Tiles format.
If I can fit images and orthomap in memory why it crashes with OOM at export orthomosaic? as i understand it should just cut orthomosaic in tiles.
Is it a bug? If it matters after crash .zip file with tiles is about 20Gb and it's broken.
Also maybe someone can give additional recomendations for pipeline how to export orthomap in Google Map Tiles format with lowest memory consumption?
