With version 2.80, only the "Cycles" path-tracing render engine supported creating a cryptomatte whereas "Eevee", the newly added real-time render engine, did not. The support to create cryptomatte images was added to Eevee with version 2.92 that was published on February 25, 2021 [ 7 ] one and a half years after Eevee was first published.
Normally there are tools to raise, lower, smooth or erode the terrain. Another way to create a terrain is to use a terrain generation algorithm. This can be for example a 2D simplex noise function [1] or by diffusion-limited aggregation. [2] Another method is to reconstruct heightmaps from real world data, for example using synthetic aperture ...
Alpha mapping is used when the given object's transparency is not consistent: when the transparency amount is not the same for the entire object and/or when the object is not entirely transparent. If the object has the same level of transparency everywhere, one can either use a solid-color alpha texture or an integer value.
In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1] It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite .
Unreal Engine 1 (UE1, originally just Unreal Engine) is the first version of the Unreal Engine series of game engines. It was initially developed in 1995 by Epic Games founder Tim Sweeney for Unreal. Epic Games later began to license the engine to other game development studios. It was succeeded by Unreal Engine 2.

UV texturing permits polygons that make up a 3D object to be painted with color (and other surface attributes) from an ordinary image. The image is called a UV texture map. [ 1 ] The UV mapping process involves assigning pixels in the image to surface mappings on the polygon, usually done by "programmatically" copying a triangular piece of the ...
An alternative free global DEM is called GTOPO30 (30 arcsecond resolution, c. 1 km along the equator) is available, but its quality is variable and in some areas it is very poor. A much higher quality DEM from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument of the Terra satellite is also freely available ...
