Hi, I have strange bug.
When I start a level, then landscape has some black artifcats
If I make some action (look back, change view, move forward, etc), then this artifcats disappear
If i close level and open it again, then artifacts appear again.
What is it? How this artifacts can be fixed?
Found out that this problem exists because of shadows. When shadows are off - no bug. When shadows are low/medium/high/epic - bug appears…
Looks like this video does not help. Because my artifacts disappear when I do something (for example move). They are not permanent…
this happens on my end too. landscapes are rendered a lil different. they use heightfields and adaptive tesselation (you can observe that in the wireframe view). this artefact in particular looks like the tesselator having a lil hickup or slow start.
It is still the shadow terminator problem regardless. The landscape rendering pipeline does not change the fact that the smooth shaded normals will not perfectly align with the shadow depths.
It is normal for the shadow terminator problem to be inconsistent based on position, if the mesh has LoDs or tesselation. This is the problem. Bias your shadows properly, or smooth the landscape out, or increase its poly count.
