I'm not knowing so much about CG/OpenGL, so I want to ask an issue about what I faced.
On Ogre 's RenderSystem_GL or RenderSystem_GLES2 or RendererSystem_GL3+ running on Windows are result nice output for texture like bellow
But on mobile device (iOS / Android), these terrain became black:
Note: I've research alot, someone 's answer said that it about the Mipmapping, should be disable Mippmapping?
Plus: I'm using Ogre 12 (migrated some code from Ogre 13.6.4), should I upgrade it to latest version?
