static QSSGMaterialShaderGenerator::ShadowVariableNames setupShadowMapVariableNames(size_t lightIdx)
This function is called for every shadow casting light for each material in the scene from setRhiMaterialProperties(). That's far from ideal, given that it allocates five bytearrays and constructs them with appends and even qsnprintf.
