Dynamic shadows artifacts

[spacegojira]

@PieBaron

Hello, I see this thread was started in 2015, is there still no good solution to cascade shadow artefacts? I am getting this in my scene, shadow bias moves the shadow far from the point of surface contact, and any subtle angles get filled with lines and jagged shadows

The problem still exists. The shadow slope bias made it a littlebit less obvious at certain areas, but it’s still very noticable.

Right now, after all this years with UE4, Epic still treat dynamic lighting without the importance it should have. And this is clear by the lack of optimization and the basic problems of shadowmaps such as the one in this thread, wich is 3 years old, and only very recently a small and quick made fix was proposed.

It’s sad that I have to agree with this. Building a game that uses dynamic lighting only has been a struggle ever since, and at every step it feels like Epic sees dynamic lighting as not important.

I would play with the slope bias, bias and the cascade amount of the directional.

I know its from a different engine, but this solutions I think are worht a try:

Would anyone that messed up with the render before give me some guidelines or tips about how to do it?

Shadow Resolution Scale, in the directional light, is capable of smoothing jagged shadow edges. But it can make other aspects of shadows difficult to adapt / modify properly…

This is sadly not a fix, as we have tried already over two years ago.

Look into this. And get some hint.

C4D Smoothing Groups inconsistent

I had the same issue with my landscape. Dynamic lighting did a good job on some of the terrain, but very pixelated like textures appeared on back side of slopes. Dirty botches of low resolution “shadows”. The only way I managed to mitigate it is to increase the landscape resolution mainly Using “Resize mode: resample” and picking 2*2 sections per component in the “Landscape” mode. After that I just started smoothing things until these “Shadows” smeared away. Not sure if this is the “correct” process but It did a better job than tweaking the “Shadow bias” and “shadow slope bias” and the cascades. Hopefully it will help someone.

Still a problem even with Lumen…
