i have a sphere geo in my scene when i apply texture to that using mantra surface shader i can see the texture in view port
but when i use surfacemodel shader and apply the same texture the texture appears black i had mention the texture path in openGL tab still its not showing the texture in viewport am attching the scene file if possible please check the scene file and help me to resolve this problem
I've attached a fixed scene. Basically you need to copy the relevant parameters from your surfacemodel to the OpenGL parts of the material and paste as relative reference.
