I created several objects, applied its material with a texture. When I render the scene it all render nicely except one. It renders black both in cycles and BI. I have tried everything. I don't know whether I have missed something or not But I'm not getting the result properly. What is the solution to this 'rendering black' problem?
Your UV coordinates are set to the wrong set of coordinates for rendering. Click on the camea icon right of 'UVMap_final' to activate it as the UV map for rendering.
The Viewport and the UV Editor always show the set of UV coordinates selected (the one highlighted blue), but this has not to be the set used for rendering.
You can fix it by adding an attribute node to assign the UV map you intent to use:
I made minor changes in the node editor:
