HTML5 Tiling Texture not working

Hello there,
I do have some weird problems tiling a texture after packaging to HTML5.
While everthing is fine in the Editor (even previewing in HTML5), after packaging the object only renders the first tile-texture. Is there a different way to tile textures in HTML5?
I hope the pictures explain the issue well enought.

take a look at this thread: Textures in HTML5 - Platform & Builds - Epic Developer Community Forums

try making the texture width and height a power of 2? (256, 512, 1024, …)
