Start Your Engine: Get a Preview of a Massive Car Material Release on Substance Source

Yesterday, we introduced Substance materials for automotive design at NVIDIA’s GPU Technology Conference. We’re taking this opportunity to release 25 fully customizable materials. Inside this release, you can find 8 MDL materials: play with them, and learn to use SBS and MDL graphs, and create advanced material effects.

This is but a preview of a massive car material release on Substance Source with over 300 materials and generators!

Our ambition? To offer the major part of the materials used by visualization experts and car designers to texture each element of a vehicle – for both existing models or concept cars.

Today, get access to an early selection of 25 flagship materials showcasing the car’s body, interior seating, wheels, dashboard and even car prototyping materials. All are specifically designed to offer photorealism and maximum customizability using MDL (material definition language).

Moreover, materials are thrusting their way up the design process. Car designers can use materials for creative iterations on design for parts, skipping cumbersome and time-consuming modeling operations.

Photorealistic Visualization

The creation of these materials required help from experts. So we called in car designers, color and trim designers, and manufacturers’ visualization artists to gather an extensive material sample library. Automotive materials are by definition a composition of very diverse materials coming together. Therefore, our team had to adapt our material creation techniques to each type of material in order to produce high fidelity digital materials.

In order to reproduce the complex effects of car body multi-layered paint coats, we used MDL in addition to the SBS procedural graph (learn how to do this in our tutorial). We exposed custom parameters allowing users to tweak each aspect of the paint - its roughness, the number of metallic or pearl flakes, and so on.

We utilised a similar approach in the fabrication of composite digital materials. We created the weave pattern procedurally and combined the fabric to an MDL graph to show the anisotropy of the carbon fibres as well as the layer of resin covering the prepreg carbon sheets.

Hybridization at the Heart of the Creative Workflow

We intended to provide materials of the highest quality without compromising creative freedom. To achieve this, we combined the accuracy of scanned samples to the flexibility procedural material creation in order to deliver fully customizable materials.

In order to create some of the interior upholstery materials we used scanning techniques to capture highly detailed leather grains and we combined them to procedurally created pleating and stitching allowing full control over new pattern generation.

Designed for Creative Freedom

In the world of manufactured products, it is vital to understand the technology behind every surface finish as well as the opportunities offered by each process. Why? To let designers tweak digital materials and finishes the same way they would experiment in a real workshop. Therefore you can adapt each material's unique parameters to your needs by changing colors, glossiness, surface grain, varnish properties, structure assembly, and many other elements.

In a matter of minutes, you can configure the whole range of a vehicle's color and material variations.

Control Material Aging Parameters

Want to render a vehicle in a real-life context? There are also tweaks for that! You can vary the level of micro-scratches, wetness, and even dirt or mud. And that works whether you need to simulate variations in use, ageing, or to render the latest concept “in situ” at the push of a button.

Need to add your specific pattern? Just input your pattern bitmap into the SBS graph, and there you go!

Prototyping Materials

We even pushed it to the point of creating materials for prototyping. You will have access to the clay used in the making of full-scale models of car manufacturer's workshops.

Material Driven Design

Modelling vs. texturing! Reduce design iterations and optimize prototyping whilst exploring more variations in early design phases.

Designers can now take the fast lane to make hundreds of design iterations without having to wait for their sketches to be prototyped in 3D, creating shapes and materials together with the right level of detail with a minimum modelling.

Tweak materials created inside Substance Designer to create a large number of design variations that previously would have taken several weeks to model using current surfacing 3D tools.

It is now easier to make decisions regarding look and feel alternatives. Designers can produce realistic prototypes with high visual quality using Substance Source materials, and apply them to speedform models.

Modeling vs. Texturing

Save Modeling Resources for Where They’re Really Needed

Get much lighter meshes to fluidify your AR/VR experiences. The design of technical parts also becomes simpler as procedural techniques enable you to visualize designs and make changes dynamically on the material.

There’s no longer any need to create dozens of different models. You can now change in a click the amount, the size, the distribution and finish of key elements of any specific part. Experiment more, in much less time than before, using fewer resources at the prototyping stage. 3D modelers can take the time to finetune the surfaces that matter.

That’s all for now. You’ve got the key – take it for a test drive! Stay tuned, the grand opening of the Autoshow on Substance Source is just a short way down the road!
