I have noticed that whenever I use a long focal length to render a scene with Cesium on, D5 either fails to render or takes an extremely long time to do so.
I am working on a pretty heavy project (approx. 26M faces), but I am using an RTX 5090 and it handles it very well with Cesium off, or even with Cesium on, but at a wide focal length. The longer I set the focal length of the viewport camera, the quicker I notice the FPS to drop off. Moving around the viewport at 15mm is around 30fps but at 100mm, it’s around 9fps. And if I tried to render at 100mm, no matter the resolution or DLSS/Super Resolution, it will fail to render. I confirmed the culprit was Cesium after opening a fresh new file and only loading in a new Cesium scene. I rendered at the same focal length and I noticed it took over 20min to render a scene at 100mm compared to less than a minute for a scene at 15mm. Changing the Maximum Screen Space Error, LOD Transition, or Range Limit doesn’t seem to affect it either.
This is incredibly frustrating to deal with as we need to be able to render scenes with longer focal lengths and it doesn’t seem possible with Cesium at the moment. I’m hoping this can be addressed as soon as possible. Thank you
