In this example, all the noise sources used to generate wear effects have been moved to the bottom of the graph. Create quick edge wear effects (Substance Designer) Watch The Video ( - ) The Directional Warp, Directional Blur and Slope Blur Grayscale nodes are all good for generating realistic-looking irregularities and wear effects in the edges of tessellated materials like bricks and tiles, says Rogelio Olguin.The video linked above shows their effects on a simple checkerboard pattern (Generators Stripes) instead would create wood grain effects.

If you compare the render of the orc character (above, right) to the raw ZBrush sculpt (left), you will notice that the fine geometric details of the helmet, like the rust and scratches, have been added through textures.

Working in this way, rather than sculpting them into the ZBrush model itself, makes it possible to update the details more quickly during look development, and makes it possible to edit the high-res geometry without losing the details.

For V-Ray, use the Config Vray option from the Export document... (If you use a UDIM-based texturing workflow, in Substance Painter 2.1 , choose Vray UDIM instead).

If you're using a standard VRay Mtl material inside 3ds Max, and generating texture maps in JPEG format, you need to assign the maps Substance Painter creates to the Diffuse, reflection (Reflect), reflection glossiness (RGlossiness) and Fresnel IOR map slots – the latter is particularly important to get consistent results between the Substance Painter viewport and the final V-Ray render.

The Directional Blur node works in a similar way, but softens the edges of the pattern.

The Slope Blur Grayscale node can be used in conjunction with a noise source (in this example, Rogelio is using the Cloud 3 noise) to generate edge wear effects.

Connect the pattern source (in this case, the checkerboard) to the Input of the Directional Warp node, and the spherical gradient to its Intensity Input.

In the Specific Parameters rollout on the right of the screen, set the Intensity to a low value, and adjust the Warp Angle setting as necessary.

As well as discussing its product roadmap and unveiling new versions of both Designer and Painter, the company invited four of its best-known users to discuss their own workflows.
