Seams incredibly noticeable - Source engine/blender issue

[SMasters]

Hey everyone, I've been having this issue for a while now and its really been bugging me. Where ever there's a seam on my model from unwrapping a weird white line appears over the seam depending on how far away/how close you are to the model. At first I thought it was my own fault on the texturing but now I'm not too sure. Anyways, here's some screenshots to explain my issue

How it looks in game and in model viewer:

(look a bit towards the right)
How it looks in blender:

My unwrap/texture if it helps:

(I know the texture/unwraps pretty bad, I tried a few things with the texture in attempt to fix this earlier)

I'm pretty sure it's a blender issue but if anyone has any ideas on how to fix this I'd be grateful

Thanks in advance.

You may have gone past the UV boundaries in the diffuse map, but it looks like the colors darken considerably right at the edges, so it's creating seams.

What I'd recommend is, instead of using black as the background in the diffuse, make it the same color as the candle (before you added shading to it). That may or may not help you. Worth a shot though. Alternatively you could just use the smudge tool and smudge the lighter part over the edges to make it more consistent. The diffuse map will look really fugly, but what matters most is how it looks wrapped on the model in Source.

PS: I personally don't think the unwrap is incredibly important on a simple little prop such as this. If it were a larger object, like a character or a vehicle, it would most certainly be very important. You could always try and unwrap the side of the candle via cylinder instead of planar. It would take a lot of manual editing to get the melted base of the candle to look right, but it might help fix the seam.

I'm not too sure about this one, but I'm more sure about it than I'd usually be, because I know blender...

I think you have to be a little more generous with space when UV mapping. I believe what you see in model viewer is an LOD setting within the vtf file.

That was the issue! It looks fine now, thanks for the help both of you
