Chaos Group shows a simple step by step workflow of how you can implement their vrscans library into your project.
This VRscans demonstration in this video we’ll take a closer look at the VRscans technology together with the VRscans material library we are going to cover the Vrscans material features as well as simple step by step workflow of how we can use the VR scans material in our project.We’ll take a look at some of the key features of the VRscans. A VRscans material is generated by capturing thousands of images of a real life material sample, the resulted scanned material is often indistinguishable from the original sample which makes the pure photo realistic.
The amount of photographs generated by the high quality Hardware captures the material’s texture in exceptional quality and detail. using all these physical data the viewer scans technology captures the materials bi-directional texture function or BTF. This approach is far more advanced and accurate than a single point bi-direction and reflectance distribution function, also known as BRDF. As a result VRscans recreate a material true surface appearance and unique response to light, to recreate a material that is physically accurate as possible from the ground up; you need to build a complex shading network which could be daunting and time consuming.
The VRscans require no prior material building knowledge or use of any reference materials. Setting up a VRscans material is as easy as just drag and drop and on top of that, a scanned material is seamlessly tile-able, which means you won’t get any seams or repeating patterns when you tile the material over the surface. The VRscans materials can be fine tuned further in terms of appearance directly in 3DS max or Maya, you can alter the color of the original scanned material to suit the needs of your scene, also you can paint on top of the color or texture without losing the materials properties or affecting the reflection color. You can adjust parameters such as UV tiling and bump strength and you can use VRscans materials with Vray materials as well. The VRscans material plugin is part of Vray version 3.5 or higher which provides the user interface for importing modifying and using the VRscans materials in vray for 3ds max and Vray for Maya.
There is no need for additional installation, once you purchase a license for the VRscans plugin you automatically receive a one year subscription for the VRscans library. In short the VR scans materials are more than just texture maps, they capture the materials physical properties and light behavior under different lighting angles, all of this is packed into a single material file that could be drag and drop onto any geometry in your scene; this approach provides incredibly fast workflow when it comes to shading your scene.
Let’s get started by downloading a few materials from the VR scans library. The library is a repository of pre-scan materials created by Chaos group with the VRScans Hardware, the library contains a large quantity of materials, currently around five hundred and fifty and it’s still growing. There are different types of materials broken into categories such as car paint, plastic, wood, leather, metal and so on. The library is accessible to all VRscans license holders and also with the extended day trial you can use the VRscans plugging along with access to the library.
