A normal map also has a depth amount slider, this defines the total height difference and should be used to tweak the look of the material. So if the overall silhouette is more important than intricate details use a height map in all other cases use a normal map. Consider what is more important: the overall height difference of the material or smaller less protruding details. The choice between a normal or a height map depends of the amount and scale of detail. So a completely white image in the roughness input will result in a completely smooth surface, depending on the category this could be a mirror (metal). 0 is smooth and 1 is rough, this translates to black=0 and white=1. The roughness map defines the surface of your material, this can be done using a slider, in which everything will have the same roughness. Both cannot be transparent and then there is the last category base & top coat which should only be chosen if you try to recreate a material which consists of distinct layers. The choice of material category should be relatively simple it's either a metal or not a metal. Also called a diffuse, color or albedo.Īlthough the terminology is sometimes mixed there is a difference between them.Ĭhoice of category, associated parameters and maps The basis of every material is a color,texture or image (photo).
Note that not all maps are needed to create a material, some maps reflect different workflows but most programs still offer all the possible ways of creating and defining material properties. To add detail and complexity to a material different techniques are used to emulate physical properties of real world materials. Many of the things discussed here are used in other render engines, for example: Enscape, Lumion, Unreal, Twinmotion, Rhino, Blender, Vray, Arnold, etc.Ī Material is comprised of a collection of maps (images) and values that represent different properties. In this section we will cover the basics of creating a material, this is not limited to Revit. The image above is made with the same file and materials but with Enscape as it's render engine. (the lighting is not correct in this particular image it is just to show the use of a background image) It is a combination of different tools available, which will be explained here. There is no post production or editing involved, everything is done inside Revit. The above image is made entirely with Revit and cloud rendering. Moreover you have more control over your assets because you have more settings. These newer assets also have the possibility of adding height or normal maps, where previsouly only bump maps were used.Ĭreating a PBR material asset or adjusting an existing one is easier than before. Or you can replace older assets with the new PBR assets. Older material assets can be used alongside the newer ones,
These assets allow for more accurate light reflection and diffusion. Since Revit 2019 there are new physically-based material assets available. This means that it will simulate the real world physical properties of materials. Revit uses a physically-based rendering engine (PBR). However this doesn't mean Revit ins't capable of producing high quality images. It's primary focus is integrating the different aspects of multidisciplinary design.īecause visualization is not its primary purpose and only part of the functionality of Revit, it is Limited. Revit is first and foremost a modeling tool not so much a visualization tool. 3.4 Choice of category, associated parameters and maps.3 Creating/Editing Revit Material Asset.
