Question by Deivore · Aug 06, 2018 at 04:09 AM · spritenormalsbumpmap

Incorrectly low scaling on sprite bumped normal maps

I'm having an issue with applying normal maps to my sprite: the scaling of the normals is done far too low, around 20% of what it should be. You can see different normals from the same sprite sheet applying to a single animation frame here:alt text

What's going on is that different frames from the normal map sprite sheet are being represented on the single still image, so different parts of the sprite are getting the normals from different animations, scaled down.

Here are the settings currently used for the normal map, material, and sprite sheet, respectively: alt text

T$$anonymous$$s mis-mapping applies to most shaders I've found for bumped diffuse lighting on sprites. The current shader I'm using is t$$anonymous$$s solution, but I t$$anonymous$$nk the issue is more likely related to an import setting as others seem to have little problems with these shaders.

Figured it out! The issue was that some animations were from another sprite sheet of a different size, so when the normals tried to apply themselves they were scaled miserably.
