Hi all.
In this tutorial ( http://away3d.com/tutorials/Introduction_to_Materials ) I added normal map for “BeachBall”. I attached the result.

How to remove this defect?

P.S. My English is very bad.

Can you also post the normal map you used?
Generally it’s a good idea to use Geodesic Spheres when mapping needs to be precise.

I expect this is from the SphereGeometry?

Good Luck!

I used different normal maps, problem is everywhere the same. In this case I used a uniform normal map 1x1 px:

Geodesic Spheres is a good idea, but I use cylindrical texture.

Yes, exactly, it SphereGeometry. If I use geometry of loaded sphere (3ds|obj|awd), reflections is not, but there is a seam on border of texture, as well as here:

But solution turbosmooth did’t help me.

Hmm, can’t see the point in a 1x1 normal map?? That could be your problem right there!

Geodesics can still be mapped for panorama type images, but instead of having 10, 20, 30 vectors meeting at the summit, you have max 3.

Another tip, avoid 3DS format completely if you need accurate normals.

I used this map in order to eliminate influence of topography / roughness. You’ve asked normal maps for this?
These reflections are an anomaly and not caused by roughness normal map.
My project - a map of galaxy with a lot of planets (spheres), some use normal maps, some not. I do not know how to solve this problem with glare.
