Semi transparent mesh problem

[Lakistein]

Hi all :),

I have a problem with meshes that are semi-transparent where you can see triangles.

Playground: http://www.babylonjs-playground.com/#DXHFD#3

Here are some images to demonstrate the problem with another model:

 

One solution is to separate mesh into multiple meshes like in image below, however that is not always possible, therefore i need something that works with single mesh

 

 

Any help is appreciated

Thanks

Hello

Did you try your model with some demos from the basic tutorial page ?

I not so in ReflectionTextures
@Sebavan

I added a single line to your playground and it starts look o.k

Make also sure your models are unwrap correctly, if this would be a normal texture, the most, what leads to this kind of problem is a wrong UV Map

Hi @Lakistein

it's mostlikely due to the way your meshes have been build,

Edit:

also, the textures on the skybox material is just enhancing the effects,

see http://www.babylonjs-playground.com/#DXHFD#5, you can still see lines from some angles, but it isn't very notiseable,

Ok, so I have discovered the problem. The mesh we were using was actually created in maya and had been unwrapped correctly. However, the model had not been triangulated before being exported to Blender and then ultimately to babylon.js.

So somewhere along the way when it was being triangulated (either by the exporter or at render time, the triangulation was apparently not correct. So by triangulating it in Maya prior to export the problem seemed to resolve itself.

Thank you for help guys

@Lakistein Can you show us the fixed version in the PG?  Thanks
