YouGroove Posted March 19, 2015 Share Posted March 19, 2015 I have seams not visible when the camera is close and lot more visibme when the camera is far. How to fix the problem ? It is mip mapping related ? or do i need to fix normal map seam manually or re make the UV seams differently to hide them ?

macklebee Posted March 20, 2015 Share Posted March 20, 2015 Would be hard to say without the model and textures. I would try looking at the diffuse and normal maps first - try them without mipmaps, uncompressed, different filter modes, etc...

tjheldna Posted March 20, 2015 Share Posted March 20, 2015 It looks like the mip mapping is going down a level which blurs the textures a bit and is bluring with a white background. In this example to help avoid you need color the green passed your uv islands... Blue line = UV Dark green = your texture color Light green = background color First off this is a bad diagram, but you can see that I have colored the dark green passed the (blue) UV lines and anything around it is a similar green. If any blurring occurs due to distance it wont matter or will be hardly visible. I'll bet on your texture all unused parts of the texture are white and the diffuse coloring stops right on the edge of a UV island? Sorry this is a little hard to get across. 2 Quote Link to comment Share on other sites More sharing options...

I re exported the normal map , and the seams is not visible , but make some strange look artifacts on long distance.

YouGroove Posted March 20, 2015 Author Share Posted March 20, 2015 The solution is to uncheck "Generate mip maps" in the normal map texture settings. Quote Stop toying and make games Link to comment Share on other sites More sharing options...
Olby Posted March 20, 2015 Share Posted March 20, 2015 I don't think you have to disable mip-mapping (as it would give you aliasing artefacts). Try switching on ClampX and ClampY on your diffuse and normal map. This way it should use the last pixel on each edge over and over again thus eliminating any seams. 1 Quote Intel Core i7 Quad 2.3 Ghz, 8GB RAM, GeForce GT 630M 2GB, Windows 10 (x64) Link to comment Share on other sites More sharing options...
shadmar Posted March 21, 2015 Share Posted March 21, 2015 Filter Mode sat to pixel usually fixes seam problems like that. 1 Quote HP Omen - 16GB - i7 - Nvidia GTX 1060 6GB Link to comment Share on other sites More sharing options...
