WebFeb 1, 2024 · Uniforms in GLSL are shader variables that are set from user code, but only are allowed to change between different glDraw* calls. Uniforms can be queried and set by the code external to a particular shader. Uniforms can be arranged into blocks, and the data storage for these blocks can come from buffer objects. Setting samplers You can tell because you didn't use the keyword struct ;) So what you're creating is an array of uniform blocks. If you want an array within a uniform block, you can create that using standard syntax: layout (...) uniform lightsBuffer { StructName lights [128]; }; Where StructName is a previously-defined struct.
