Hello Unreal community,
I am working with UE4 for a few months and I love it, however I have one very important question. I did a landscape about 4x4 km, and did in speedtree simple model of leaves so it looks like a grass. I used a foliage tool to paint my landscape with that test grass, however when I tried to build my scene, engine said “Large actor receives a pre-shadow and will cause an extreme performance hit”. I found, that this issue can be solved by disabling dynamic shadows for the grass, but in that case grass will be with static shadows? What is the best solution for grass and also I will be placing a lot of grass on my landscape, will that hit performance? I need animated grass not only static but with bending leaves, please share your experience.
With all respect
