The shadow casted by rocks low poly looks weird. The edge is hard but it seems to be some tiling inner, and I don’t know where the tiling pattern being from.
If I turn down the distance field shadow of the default light source(the directional light), the far prospect weird shadow gone but near one still exist.
If I just set the directional light to invisible, all the shadow gone and scene turns red.
If I just shut the “generate distance filed” option down in the project setting , it still has this wired shadow.
By the way it only affects landscape as I discovered now.
I would be appreciate if you could help me, thank you guys.
Yes you’re right. But do you know or expact where does this pattern comes from? LayerHeightBlend? I don’t remember landscape has something properties like “Shadow Maps”.
It seems I found the causing, it is a landscape blend layer heightmap. If I scale the height map tiling, the pattern changes. But things only happen on this layer, the other layer keeps their function as usual.
Newly found. The two snow layer has identical nodes struct, just different texture sample(pictures).
but “SnowSoft” works well while “SnowHarsh” just makes it heightmap mask every where and tiling no matter how I changes its parameters.
It seems solved just now by unknown reason. I simply force delete all the material instance and re-instance them, then the strange thing gone.
Suspect it to be some unknown bad temps in material instance during some operations or version upgrading.
