Methods and content rendering systems for rendering Augmented Reality (AR) content for textureless objects are disclosed. The content rendering system captures one or more image frames associated with objects and transmits to a cloud server to detect one or more textureless objects along with one or more associated buffer Regions of Interest (ROI) based on a pre-trained object detection model. A grid index associated with each buffer ROI defines a position of the one or more textureless objects in each buffer ROI. The content rendering system obtains AR script from the cloud server based on the detected one or more textureless objects. Thereafter, based on the AR script, AR content associated with the one or more textureless objects is rendered in real time at the position of the one or more textureless objects.
