Are those at the edges of individual textures, or do the figures use a single texture? And which shader are you using?

Hi, David thanks for the reply.

I'am using a Diffuse shader for all, individual textures, I am just using the Color feature to colorize the models, so I'am not using and RGB texture.

Basically I just painted the different polygons with different colors on Google Sketchup.

And yes, the artifacts appear at the edges of the polygons with different colors. Besides, in the gray guy tie, the red tie, the tie is an extruded polygon with a solid red color, but even in that plane the artifact appears as a banding effect.

thanks again!

Check the mobile 'Quality' settings of your project:

Edit > Project Settings > Quality

You can set antialiasing and other graphics related settings here.  Use the black arrows below your target platform's checkbox column to set the default quality level.  You can also add your own custom quality levels and toggle them through script (e.g., Video Settings menu with a switcher for "Low", "Med", & "High" graphics levels).  You could even set these per-device generation at runtime to ensure optimal performance on older devices.

You can also edit the player settings:

File > Build Settings > Player Settings

Choose the correct platform in the inspector.  Note the settings 'Device Filter', 'Graphics Level', and 'API Compatability Level'.

If you're still having trouble, upload a unitypackage file and we can help you troubleshoot your issue.

Do anybody have a solution for this problem ?

I experience it also :(

ps: I dont understand what that means:

It means that you go to the Edit item in the menu, open that and select Project Settings and in Project Settings set the Quality.

Also I'd recommend posting these sorts of questions to Unity Answers as well - http://answers.unity3d.com/index.html

Someone there has probably run into the same issues.

That was what I did not understood: i do not use (or know) unity.

I am just using the qcar library.

Hi vincekillian!

Thanks a lot for your suggestion.

I have been playing around with the quality settings and it seems that it actuallly reduce the artifacts a bit but it don´t make them dissapear. I even use the Fantastic quality settings are the artifacts are still noticeable and also set custom settings with the same results.

However I tested the same app in a Motorola XT and and Samsung Galaxy SII and no artifacts appeared, all looks clean!

I think that it probably has to be something related with the OpenGL implementation of my Samsung Galaxy Tab 10.1.

I will keep trying other suggestion to see if I found a solution and I will let you all know!

Hi Nerith!

What device are you using?

As I said in another reply in this thread, I tested my same app on two android powered phones (Motorola XT and Samsung Galaxy SII) and no artifacts appeared. I am not sure, still researching but maybe it  has something to do with the OpenGL implementation in our devices. I will let you know if I found a solution that you could apply even if you are not using Unity.

This is my post in the Unity Answers forum , asking for help regarding the same issue here

http://answers.unity3d.com/questions/283497/rendering-artifacts-at-edges-of-3d-models-android.html

I hope it could help other guys running with the same issues. I still need to test some suggestions that the Unity guys posted.

@Nerith please post a description of your problem in the Android forum. Does is appear as though triangles have dropped out of your model? If so, make sure you have triangulated the model, any 3D modeling software should be able to do this. It is also possible that the model has triangles winding in different directions (some clockwise, some counter-clockwise). This can happen when the normals are incorrect in the modeling software. In this case, try turning off culling: glDisable(GL_CULL_FACE);

Thank you David, that was that !

It seems that GL_CULL_FACE is enabled by default on iOs, but not on android !

Regards,

Cyril
