Black lines outlining model..

[tonyd927]

Ok, So Ive UVWed and baked my maps for this knife Ive made and now Im getting alot of buggy maps. Im not sure if theyre coming from my normal, ambient occlusion or diffuse but along the edges and seams there are extremely noticeable black blotches surrounding my model, Im not sure what Im doing wrong here... Any help?

I am just not grasping the concept of normal mapping and baking maps. Ive done countless tutorials and it's still coming out very buggy, even when I follow each step to the t.

Guessing it probably your normal map,
quickest way to check which map it is to mute or disconnect the map until you see which one.

But assuming it is the normal map it could be:
The red or green channel needs to be flipped (can be done in Photoshop via the "channels tab" next to layers)
or you haven't got enough padding on the normal map bake.

My low poly model was pokin out of the high polys silhouette in several areas, also, I baked my maps in 1024x1024 tgas but when I baked just the normal map in 2048 the problem is barely noticeable

Looks like you have not checked cage before baking. check Ray misscheck on and see the result . You will find red marks in your baked output. that part are not properly projected. So then you need to sed cage properly on that area. never use automated Projection cage. Reset it and then do it your self. It will give you much accurate and fast output. I hope this will help you.

It's difficult to be precise in exactly what could be causing the issue with just the pics you posted up. Can you post the baked textures from the output and also a screenshot of the 'Render to Texture' settings you have?

Since you are saying the black lines are barely visible when baking at higher resolutions I am gong to guess that you forgot to turn padding on.

If you have the photoshop plugin of xNormal, simply select all the "negative space" on the textures and delete it so it is transparent. Than simply run the Dilations filter. (Filter>xNormal>Dilation..)

If you do not have the xNormal plugins, just rebake your textures and this time make sure you enable padding.

It might also be a good idea to post which software/tools you are using.

Padding was going to be my guess also.
