Some roof normals seem incorrect #50

Closed RedAuburn closed 1 year ago

these sides of the roof should be in shadow, maybe the normals are being smoothed?

The tiles normal map looks like it could be in world-space or something.

Without the current normal map, it looks better. But it still looks like the geometry normals on the roof ridge aren't right: with current normal map / without (better) bitmap

Hmm, it's hard to say whether it's expected behaviour or not. Maybe the normal map is a bit too extreme.

Normal texture for roof tiles had a slight slope baked into it. It should be better now. But besides this normal maps work correctly.
