Hi, I have a heighfield of 10912 x 10912 px with multiple heightfield nodes using a cop network texture. I try to instance 1,6 millions of trees with the heighfield_scatter node, which is no problem in the scene view, but with Mantra renderer. Mantra eats insanely much RAM, no matter I use full geometry or packed primitives of the trees. The tree loaded as full geometry has 26 MB and as packed primitive 14 KB. The render resolution is 6000 x 4000 px. The maximum number of trees, which I can render without chrashing Mantra is 800.000. I have also tried instancing through the instance node, which changes nothing. Do you have any ideas for another solution as upgrading to 256 GB RAM ? Kind regards System: Core i7 7820X, 128 GB RAM, GTX 1080 graphics card
