What is curvature map substance painter?
The curvature baker allows you to extract and store concave and convex information related to your mesh. The black values represent the concave areas. The white values represent the convex areas. The gray values represent neutral/flat areas.
What is curvature mapping?
A curvature map is a texture that stores the convexity/concavity of the mesh. Also called Concavity, Convexity, Pits & Peaks, Worn Edge. A Cavity map is different, it stores ambient occlusion which is limited to small crevices only.
What is a curvature texture?
Curvature is a texture that effectively samples the underlying mesh for curves. A region around each shaded point gets sampled with additional rays (similar to Dirt) and all additional normals are averaged to get a “smooth” normal at the original point. This normal is used to compute the color.
What is cavity map?
Cavity maps are essentially the blue channel of a normal map and represent dark shading in the crevices of the model. They can be useful as a multiply layer over a diffuse color map to accentuate details or as a diffuse map in Maya to help punch up the high-frequency details in a render.
What is a position map substance?
The Position map from mesh baker computes the location of the high-poly mesh geometry and save into a texture. It is similar to the base position baker but can produce more accurate results. Available in: Substance Designer.
What is profile curvature?
Profile Curvature is the curvature of the surface in the direction of the steepest slope (in the vertical plane of a flow line). The Profile Curvature affects the flow velocity of water draining the surface and influences erosion and deposition.
What is the use of position map in substance painter?
What is thickness map?
The Thickness map from mesh is very similar to the ambient occlusion baker, but it casts rays from the surface of the mesh to the inside. This texture can be used in a Sub Surface Scattering (SSS) shader or for masking textures. The texture properties are defined as: Black values represent the thin parts of the model.
Is curvature the same as slope?
The slope of the curve at a point is equal to the slope of the line that best approximates the curve at that point, a.k.a. the tangent line. The curvature, on the other hand, is the inverse of the radius of the circle that best approximates the curve at that point, a.k.a. the osculating circle.
What is curvature map in AutoCAD?
A curvature map is a texture that stores the convexity/concavity of the mesh. Also called Concavity, Convexity, Pits & Peaks, Worn Edge.
What is the difference between curvature map and cavity map?
A curvature map is a texture that stores the convexity/concavity of the mesh. Also called Concavity, Convexity, Pits & Peaks, Worn Edge. A Cavity map is different, it stores ambient occlusion which is limited to small crevices only.
What is the purpose of using curvature?
Curvature can be used to mask where the surface would get more wear or where sub-surface scattering might occur (convex), where it might accumulate more dirt (concave), to check for surface continuity, etc. Concavity (green) & convexity (red), made with rebb’s r7_vertCurvature.py.
