vex input error lightfall

VEX is a high-performance expression language that is utilized extensively in Houdini, including the creation of shaders. VEX evaluation is often quite efficient, producing results comparable to generated C/C++ code. It is not a replacement for scripting, but rather a more compact and efficient general-purpose language for creating shaders and custom nodes. VEX is partly based on the C programming language, but it also borrows elements from C++ and the RenderMan shading language. This error notice typically comes when you attempt to play any game-related vex enemy-related activity. This error’s precise cause is unknown, and the Bungie Help pages make no mention of it. You can also get vex input error resetting vex lock. The likely cause of this error, though, is a problem with the connection between players’ devices and the Destiny 2 servers.

Where is VEX utilized? 

VEX is utilized in various places in Houdini, including:

  • Mantra utilizes VEX for all shading computations. This comprises shaders for light, surface, displacement, and fog.
  • Composition – You may develop complicated custom COPs in VEX using the VEX Generator and VEX Filter COPs. The expressions run 1000s of times quicker than the Pixel Expression COP and evaluate extremely near to C/C++ rates.
  • Particles – The POP VOP lets you accomplish practically anything that POPs can do. It is feasible to construct a single VEX function that performs the function of several POPs. Because the VEX code is limited to a single operator, it usually runs quicker than a network of POPs.
  • Modeling – You may use the VEX SOP to create a custom surface node that manipulates point properties. This can move points, modify velocities, and change colors. You may also group points and do a variety of other helpful functions. VEX SOPs are often 10 times quicker than point SOPs.
  • CHOPs – The VEX CHOP allows you to create your CHOPs. The CHOP functions can handle an infinite number of input channels and process channel data in an infinite number of ways. In some circumstances, VEX code can outperform compiled C++ code.
  • Fur – VEX is used to develop procedural fur behavior.

Contexts of Vex Language:

VEX programs are created for a specific purpose. For example, a shader that controls an object’s surface color is created for the surface context. For the light context, a shader that determines the illuminance of light is written. And For the chop context, a VEX application that produces or filters channel data is developed. Which functions, statements, and global variables are available are determined by the context.

  • The standard C statements are supported by VEX. It also enables shading-specific expressions like illuminance and collects loops, which are only usable in specified circumstances.

Built-In Functions:

  • VEX has a big built-in function library. Certain functionalities are only available in specific situations.

User-Defined Functions:

  • Functions are defined in the same way as C functions: state the return type, function name, and parenthesized list of arguments, followed by the code block.
  • Parameters of the same type can be declared in a comma-separated list without the type being expressed again. A semi-colon must be used to separate further arguments.

Main (context) function:

  • This function usually handles data and updates global variables. The return statement does not  return the value of the context function. The context pages contain a list of the global variables that are attainable and available in each context.


  • When the types on the operator’s left and right sides match, the comparison operators for strings, floats, and integers are defined. Integer types are created by the operations.
  • The string matching operator (=) is defined when a string is present on both sides of the operator. Its use is comparable to applying the match function on those two values.
