Animation Exterior - Can I use PT+PT?

[CiroC]

Hi guys,
Basically, I have an exterior scene, with loads of vegetation (it is a aerial view) and I have a camera that goes around the scene. No moving geometry, just the camera. Can I use PT+PT? Will I have any flickering?

Thanks for the help

i believe PT is better than UHD ... so , yes you can ...
but needs more RAM ...
and less ALBEDO ...

Can you explain what you mean by that?

You can render an exterior scene with PT only. UHD Cache is mainly useful for interior shots, where GI bounces are very important. In exteriors, you usually see mostly direct light. If there are no moving objects or lights in your scene, you can also save your UHD Cache and re-use it for all frames. There is nothing wrong with it, and there won't be any flickering.
