WebApr 8, 2024 · Array of basic type: one entry with the name of the uniform suffixed with [0]. E.g. uniform vec4 b[]; will result in b[0]. Struct type: one entry for each member of the struct. E.g. uniform struct { float foo; vec4 bar; } c; will result in c.foo and c.bar. Arrays of structs or arrays: each entry of the array will generate its own entries. E.g. WebThis rule also applies to the struct inside the std140 struct. TBH, I dont like implicit padding, I usually add some explicit padding variable to the struct, so it matches what I have in the CPU side. Might be worth to change your PointLight struct like this.

The syntax is the same as in C, with some limitations. A struct is made up of a sequence of named members, which can be of different types. The type of a member can be any of the built-in types, an array type, or a previously defined struct type. For example, ram apotheke meran
