In this episode, Ruben (TheGameDev.Guru) exposes the runtime performance costs of Unity lightmap baking that nobody talks about. While everyone shows off gorgeous baked lighting, they conveniently skip the frame rate hit, memory bloat, and draw call explosions that come with poor lightmap settings. You'll learn the five critical settings that make or break lightmap performance: lightmap count and batching breaks, filtering modes and bandwidth costs, compression formats that actually work, mixed lighting modes ranked by performance, and texture streaming to cut memory overhead. Perfect for Unity developers targeting mobile, VR, or any performance-sensitive platform who need beautiful lighting without tanking their frame rate.
