List of Incomplete Material Node Functionalities

Below is a work-in-progress list of Substance Designer's material node functionalities unimplemented by DiffMat. The nodes in question can still be successfully translated but the involved parameters and features are ignored.

Blend

  • Blending mode "Straight alpha blending" and "Premultiplied alpha blending (copy only)".

Curve

  • Per-channel curve adjustment (R, G, B, A). DiffMat currently maps all channels together using a unified curve as if the input image were grayscale.

Distance

  • Distance transforms using "Manhattan" and "Chebyshev" distances.

Gradient Map

  • Gradient interpolation mode "Smooth" with a "Smoothness" parameter.

Bevel

  • The "Corner Type" parameter ("Round" or "Angular").
  • The "Use Custom Curve" switch that enables an optional height curve input slot.

Quantize

  • The "Offset", "Slope" and "Slope Curve" options, which have just been introduced in the latest SD update.
  • Following the said update, the Quantize node is now implemented by a Pixel Processor and behaves somewhat differently from previous versions.
