Summary0001429: Landscape edges have shadows
DescriptionThis comes from landscape edges being marked as material borders. They shouldn't at least when the sides are not open. See screenshot.
Steps To ReproduceStart Tests.ocf/Minimal.ocs, walk to the left or right edge of the landscape.
TagsNo tags attached.

I don't think this is a problem. The border is "magical" anyway, why shouldn't it drop a shadow?


Clonk-Karl (administrator)

To me it looks unnatural somehow. Like there's a 90 degree cliff right where the landscape ends. Maybe the clonk world is a disk :P

By the way, on the other side of the map the edge is actually brighter, not darker than the rest of the material. Like there's an extra light source somewhere on that side of the landscape.

Well, but is there a way to solve it without having a ton of coordinate border checks in the shader code? Like a texture addressing mode that mirrors the borders (but would that work with non-POT?)


Clonk-Karl (administrator)

The material edges are computed in CPU. And it makes sense that way, because if they were in the shader, they would need lots of texture fetches for each fragment.

I'd expect a fix for this to be fairly simple actually.

Changed Target Version to 8.0

This isn't release blocking and even if the fix is easy, no one's done it yet! But can be done anytime.
