Texture Artist Andrey Frolov, with whom we had the opportunity to speak earlier this year about the workflow behind a vibrant cloth material created in Substance 3D Designer, has now released an update to his custom Blur By Normal node featuring several exciting improvements.
This node blurs an image based on a normal map, running 64 iterations that blend with the previous one using Copy, Max, or Min modes, with an opacity of 1/n, where n represents the current iteration. This means the pattern gradually fades with each iteration, similar to a slope blur.
Each iteration uses a modified Vector Morph Grayscale node and offers three modes for calculating point values:
- Normal mode: Uses the point's value along the normal path;
- Blur mode: Averages the values along the path;
- Max mode: Uses the maximum value along the path.
