Clone material to re-used it

[vignalbrice]

Hi everyone, My issue is the next one, i want to clone my ProjectMaterial, but when I do material.clone() I get this error :

"Error: Invalid camera passed to the ProjectedMaterial"

This is my code:

        let cloneActiveMaterial;
        let cloneMaterial;
        if (this.activeMesh.name === mesh.name) {
          mesh.camera = projectionCamera
          cloneActiveMaterial = mesh.material.clone();
        } else {
          cloneMaterial = mesh.material.clone()
        }
         if (this.activeMesh.name === mesh.name && properties.elem === "Texture") {
          this.activeMesh.material.map = currTexture;
          this.activeMesh.material.camera = projectionCamera
          this.activeMesh.material.needsUpdate = true;
        }
