Dynamic Light + Foliage Tool
I hve an ongoing issue where movable meshes placed by the foliage tool are rendering as extremely dark when shadowed by static meshes. I have been battling this for the better part of a year, so I'm quite ready to have it figured out!
The scene is made up of the following lighting-wise:
What happens, is that it seems the foliage tool or lightmass hits a critical "mass" (bad pun?) when placing foliage. They will appear fine in the viewport as I place them, then as soon as I place one too many, all previously placed objects start rendering very dark when shadowed. If I remove the last mesh, all previous meshes return to rendering as they should. What is more bizarre, is that the surrounding landscape uses the same meshes placed with the landscape grass tool, and they work beautifully. It seems quite random too - one day, it will be working ok-ish, then I try and refine it and start again and it gets much worse.
Other things to add
I've turned off all AO on the main foliage in the images so they appear bright and obvious, and I've just plopped them on all the meshes, but they actually need to only go on the surrounding bits of bare site.
This is driving me bonkers, so any suggestion is appreciated. I'd be quite happy to be shown I'm a moron and missing something obvious!
So it sounds like you are hitting the max combined lightmass size of your foliage instances per landscape component. When using the foliage tool you can only paint a set number of instances per component up until they no longer fit within the lightmap size limitation placed on each component.
This is why you get an override within the foliage tool itself to set the desired lightmap resolution on each foliage type. Take a look at the documentation we have provided on this procedure.
Let me know if you have further questions.
