Normal Mapping pixelated

FaceofBoe

Hi everyone I have viewed polycount for a long time and recently joined, I need help with a normal mapping problem I've run into.

I was following this tutorial
http://www.game-artist.net/forums/spotlight-articles/43-tutorial-introduction-normal-mapping.html

and i've seemed to follow all the steps correctly but my normal map applied comes out pixelated like this:


^ is what it looks like in photoshop. When i render it though it looks fine in the render window



here is what it looks like applied:



and here are my settings:




If anyone could help I would really appreciate it, it's probably something simple that I'm missing /facepalm.

First, never trust what you see in the render window as far as normal maps go. Always open it up in photoshop to get an accurate look at it.

Could you post a shot of you high/low poly/cage? Are you sure your cage is pushed out from the high poly?

Bake it in Scanline (forget about Mentalray) and report back to us.

Mark Dygert

Are you baking that entire thing or are you baking just one part and tiling it, (like you should be doing). You can use a bigger map and tile it to help minimize the low res pixelation effect.

What kind of normal map are you out putting? It looks like World space instead of tangent. Click the Options button next to the projection settings and make sure its set to Tangent.

Did you add a normal map material to the bump slot, then put your normal map into the map slot of the normal map material?
