Realistic texture perception in Extended Reality (XR) requires tactile feedback that simultaneously addresses the fundamental perceptual dimensions of hardness, roughness, and warmth. However, current haptic solutions often rely solely on vibrotactile feedback, which alone cannot convey the full spectrum of tactile sensations. This paper presents a multimodal texture rendering method that combines three distinct haptic modalities—force, vibration, and temperature—to provide all required perceptual dimensions. We developed a multimodal fingertip haptic display to deliver these stimuli, and evaluated its performance through perceptual user studies within a Virtual Reality (VR) experimental framework. This framework assesses the modalities, both in isolation and in combination, to examine the robustness of the mappings between stimuli and their corresponding dimensions. Furthermore, we demonstrate our multimodal method by rendering real-world materials such as wood, metal, and water. A subjective evaluation with 48 participants indicates that users can reliably identify most perceptual dimensions, and that the integration of more modalities consistently improved texture realism compared to representations with fewer. These findings validate the effectiveness of our multimodal texture rendering method and advance the design of immersive, texture-rich XR experiences.
