Some textures not showing once I play the game on the phone (galaxy S3)

Placed a static mesh from the free infinity blade stuff (thought it was mobile compatible?) but once I run it on my phone, the texture is missing and it’s only for certain areas. For example, I have bridge where the sides have texture but the actually walking area doesn’t appear to have any texture so it’s all an off white color.

I know there are going to be some requirements for mobile textures but I don’t really understand them well.

Even if you use ETC1 ?

how do you deploy it? through Editor directly to phone or after packaging and copying apk-file? When I used second deploying all lights were broken, in first weren’t

Are you using C++ at all? I had an issue once where the textures were fine on PC, and not on Android and it was because I wasn’t properly including the materials in C++, so the textures were never actually packaged with the game.
