Hello,
I am having trouble to get usable results with some assets. In the next image you will see how the grass does not get a “proper” shadow on it from the white columns on the right part of the image. most of the upper part of the grass is Lit as the sun was hitting directly on it, as you can see in the left part of the image :
:
this is a foliage actor, the asset has a material with masked and WPO on it. I already watched this video Troubleshooting FOLIAGE issues in Unreal Engine - YouTube and just in case, eventhough the problem is not the same, I tried the “evaluate world position offset” checkbox wich makes no diference (even with a blueprint and foliage actor) and also the “foliage.forceLOD” console command
I also checked what happens when using the asset without foliage tool, and the results are exactly the same, so I guess Foliage is not the problem. I also tried to see if the material is the problem, so I created a new material just with the mask and a grey color, nothing else…the results are not promising, since it also looks really bad:
So by elimination, it only remains Lumen, I guess, as the source of the problem. Any ideas in how to get a more natural shadows casting on those grass assets? Like the result from the path tracer?
thank you
