Bending gives you better control over projecting decals on cylindrical surfaces such as bottles or glasses, or even on spheres thanks to bending in two axes:
Stacking Decals
Overlaying many decals with varying vertical positions and options can quickly produce good-looking results:
Affect Base
Only “Displacement” is enabled under the “Affect Base” section. This way, only the displacement map of the decal affects the base object's material. Otherwise, we would be also affecting other channels such as diffuse color or reflectivity.
By the way, the ripples on the water surface are also achieved with a decal using a procedural gradient map.
Real-world map size
With the "Real-world map size" option enabled, the size of the textures used in the Corona Decal can be precisely controlled using real-world units such as centimeters or inches. In the below example, the size of the hole texture (opacity) is set to exactly 1.5m x 1.5m and the bricks have a realistic scale as well:
Front Back Map
Corona Decal can be used alongside Corona Front Back Map to create advanced material effects. This allows for precise control over decals based on front and back face rendering, enabling more flexible material setups.
