I tried to: Add a Nanite mesh sharing a material with another existing Nanite mesh Add a Nanite mesh with a brand new material Neither two operations resulted in any additional draw calls. Mar 22, 2023 · Hi, Steps to reproduce: 1- New 3rd Person Project. Plenty of people have tested the optimized LOD workflow vs converting it to Nanite. Complex organic/natural static shapes which are more much more difficult to optimize nicely and that often look shitty as you go between different LODs. Im amazed you even managed to get HLOD to work properly as i can’t even get that far yet. Aug 29, 2021 · As we all know, UE5 and Nanite has provided us with massive improvements with respect to the rendering of geometry. The level we want to optimize uses world partition . but when i tried in game, there was a massive, really massive ram usage. Nanite does what HLOD does.

But, if you can pre-compute that (hlod) it easies up what nanite has to do. We'll take a look at how to access World Partition, explaining its UI, 首先，Nanite网格体本身是一种HLOD结构，它依赖的方法是将小三角形简化为大三角形；在差异小到无法感知时，Nanite会选择较粗糙的三角形。 这在连续的表面上效果很好，但在聚合体（aggregate）上效果不佳——从远处看时它们更像是部分不透明的云，而不是固体 Aug 23, 2021 · It’s just the HLOD that seems to not be working.
