WebSep 16, 2016 · Opengl - Glsl for loop array iteration bug. I am facing a really weird bug. On an old copy of my engine, i was doing a loop to render all the lights in my scene: for (int i = 0; i < numLights; i++) { finalColor += ApplyLight (lights [i], diffuseColor.rgb, normal, fragPosition, surfaceToCamera,specularColor,shininess); } WebJun 8, 2024 · This means that you can have an array of arbitrary length in an SSBO (at the end, rather). The actual size of the array, based on the range of the buffer bound, can be queried at runtime in the shader using the length function on the unbounded array variable. SSBO access, all things being equal, will likely be slower than UBO access. sporty\u0027s duluth mn
