Shadows are lines instead of a gradient
Since Im just trying stuff, I was using the "template_floor" found in the geometry folder from the template. So I also made a grid with a good amount of faces and of course, made the uvmap. No luck, still the same.
I notice this happen with some textures but not with others. For instance: m_basic_wall m_basic_floor m_frame m_lamp m_metal_gold m_water_lake m_wood_oak m_wood_walnut m_colourgrid_lowspec
They all sufer it, in the case of the frame and lamp mats I could understand it cause Im using them on grids and floors, but the others too? The concrete and brick series have no issues for instance, Im trying to find whats the conexion, but Im not succeding. Someone had this problem and fixed it?
My lightings settings were in production, I placed them in High now. The proyect is set for shipping. I tried increasing the lightmap size settings, no results either.
pd: Oh I forgot to mention, this also happens a lot when the sun position is the one in the picture. I have another proyect with a day/night cycle, works great but at every dawn I get this lines which move like a moving curtain
This is a problem of self-shadowing. There are a couple ways of approaching this, depending on the needs for your scene:
If you don't need the surface in the picture to cast any shadows, you should be able to just disable shadow casting for that mesh. This will make the problem go away completely.
If that surface has to cast shadows, you can try playing with the shadow bias setting for your directional light. This won't completely fix the problem, but it can reduce it.
