How to fix the seam in texture when camera far away?
When I move camera close to that region, there is no problem. But if it move far away, I see the seam line
Bump!! Anyone help!!!
Is this Beast or external lightmaps?
Usually seams like that are either mipmaps on one of your textures, or lightmaps… or z-fighting with polygons overlapping.
In the case of mipmaps just turn them off on the texture and/or lightmap, and see if that resolves it first.
If it does, then you can modify your texture, skin, uv or whatever to give yourself more ‘bleed space’ so that you don’t have the artifact.
If it is polygon overlapping, then clean-up or adjust your meshes so that isn’t happening anymore.
I use external lightmaps.
There’s no overlapped face or unwrap.
We baked lightmaps using vray, that ceil is quite long, so we have to break the uv to keep the resolution. That seam goes at the breaking uv region
Then disable mipmaps for the lightmap on both objects, and you’ll probably see the seam go away…
Which means you’ll need to extend the baking seam/padding, as well as ensuring enough space between uv borders.
I use only 1 object, just break uv in unwrap and already turn off all mimap
I will check the padding. Thanks
Or…increase the aniso level on your textures which can also contribute to the issue.
already tried this but just reduce 10% 
Try changing format compression and tinker with the wrap and filter modes.
I already with all setting, I also use texture with TrueColor format
