bandrewk Posted April 17, 2014 Share Posted April 17, 2014 Hello, I am experiencing some issues with assets that are being ported to Leadwerks, a few of them are showing white artifacts / lines. How can I fix that? Am I using wrong settings somewhere? I attached a video to demonstrate this behavior. Texture settings: Material settings: Thank you!

tempest Posted April 17, 2014 Share Posted April 17, 2014 That's an interesting issue. But I doubt that it has anything to do with the textures themself. As you can see those on the far right which are well lit are pretty consistent. It's just a guess but the lines that you see are probably due to specularity. Could you try setting it to 0 and posting the results. Quote Link to comment Share on other sites More sharing options...
bandrewk Posted April 17, 2014 Author Share Posted April 17, 2014 Changing the spec. does not change anything at all. However, I figured out that changing the diffuse color is also changing the color of the artifacts: Perhaps this is a shader error? Quote Link to comment Share on other sites More sharing options...
Guppy Posted April 17, 2014 Share Posted April 17, 2014 Does your diffuse have an alpha channel and if so is it solid? Quote System: Linux Mint 17 ( = Ubuntu 14.04 with cinnamon desktop ) Ubuntu 14.04, AMD HD 6850, i5 2500k Link to comment Share on other sites More sharing options...
bandrewk Posted April 17, 2014 Author Share Posted April 17, 2014 Does your diffuse have an alpha channel and if so is it solid? It does have, and yes as seen on the screenshots above. The artifacts are also appearing if I set the material to a development one: Quote Link to comment Share on other sites More sharing options...
tempest Posted April 17, 2014 Share Posted April 17, 2014 If you look closer you'll see lines that are not on the mesh. I suspect that it's a rendering bug. There was a similar thread but I cant seem to find it (it might've been deleted). If i'm not mistaken, the explanation was - problem with the graphic card. I don't know if that's true. What graphic card do you have? Quote Link to comment Share on other sites More sharing options...
bandrewk Posted April 17, 2014 Author Share Posted April 17, 2014 I sent Josh a pm about this, hopefully he'll look into it. Graphics card: NVIDIA GeForce GT 750M: Quote Link to comment Share on other sites More sharing options...
tempest Posted April 17, 2014 Share Posted April 17, 2014 I'm very intrested to know what is causing this. Hopefully Josh would be able to tell us more. Quote Link to comment Share on other sites More sharing options...
Josh Posted April 18, 2014 Share Posted April 18, 2014 Having the files to actually produce the problem would be helpful. Quote My job is to make tools you love, with the features you want, and performance you can't live without. Link to comment Share on other sites More sharing options...

YouGroove Posted April 24, 2014 Share Posted April 24, 2014 Post your files publically if you want, we could take a look. Be rassured we won't use your texture to make the next big AAA mmo Quote Stop toying and make games Link to comment Share on other sites More sharing options...

YouGroove Posted April 25, 2014 Share Posted April 25, 2014 Some of us would have graciously give some of our time to look at your problem, even on some 32*32 pixel of images. Good luck with your problem. ----------- I would say open diffuse, specular, normal map in Gimp and get rid of Alpha channel on all three maps and test again to see if it is what is causing the problem.

digman Posted April 25, 2014 Share Posted April 25, 2014 Without having the files I am just guessing but I know a NDA will not allow you to post publicly. Are the fence railings (not the post) just flat polygons or do they have true depth... Check your model for duplicated vertices and merge or remove them. Also check for flipped normals... You might have done the above already but did not mention this in your post. Could it be a light bleed problem? Quote Link to comment Share on other sites More sharing options...
