Bump (Normal) Mapping - Any specifics?

Hey guys, so, I decided I want my game to look pretty, and I know that normal maps are the standard right now.

I’ve generated a normal map from a detailed model, assigned the UVWs, and I’ve exported a normal map-- that pastel looking image.

On a lower poly model, I set the shader to Bumped Diffuse, set my texture and my normal map (and checked to make sure that the normal map is set under import settings). However, I see no change in the model.

I’ve tried turning on a lightmap and baking my object, but that didn’t do anything (are you even supposed to lightmap the object? I’m trying to bump map my player if at all possible, and have it respond independently to the location of the light source)

I’ve tried researching this, but I didn’t see much other than the Valve technique of Radiosity Normal Mapping, which is certainly over kill for what I’m trying to achieve (though, an interesting read).

This seems to be something fairly straight foward, though this is my first time through it.

Thanks!

It should just appear, but it’s entirely possible your video card is old and can’t use normal maps maybe? Hard to say, but it should just work if you set things up correctly.

Psst, I don’t want to bump this unnecessarily, but I started a request in the feedback section some days ago suggesting implement “Radiosity Normal Mapping” for Unity. Some say it’s already a feature in Beast, just not activated for Unity yet. Some voices wouldn’t hurt though, since it seems more people are interested in this feature :slight_smile:

Your normal map won’t work without pixel lights lighting it. Add one and you should see your normal map taking effect.

TwiiK, I set a directional, point, and spot light to Render Mode: Important (Manual says this forces pixel lighting), and that did not seem to fix it :-/

Would you mind posting your 3D package, normal map, UV map, and a resulting screen shot and also your normal map’s import settings in Unity?

Would make it a ton easier to debug.

Sure, I’ll get around to it later today.
