Hi guys, the texture i used in diffuse is used in displacement with paste instance. the texture mapping coordinate changed immediately when copied to displacement, but if displacement is cleared, it showed the right result. sorry, my english is not good enough to explain it in details. you can check the video.
i attached the scene which is same with the attached scene in https://forum.corona-renderer.com/index.php/topic,10204.0.html.
