To increase the size of this texture, we can use the appearance manager. As you can see, the size of the texture became bigger. Now we want to create a pbr material in vray for revit. First, we need to download the textures we want. We download Albedo, Roughness, Normal Bump textures. We want to make wet asphalt material. We place the downloaded textures in the generic material. Now we attribute this material to the street. As you can see, the wet asphalt material is well made. As the asphalt reflectivity increases, the rendering time is increased. We can control the size and rotation of this material from the appearance manager.
