This tutorial takes you through the process of combining 3D models with 2D photographs in Blender. Starting with the fSpy tool, you’ll learn how to set up accurate perspective alignment using one-point perspective, ensuring your 3D model fits perfectly into the scene. Next, the tutorial dives into creating essential geometry like floors and walls and applying textures that match the photograph’s environment. By leveraging Blender’s powerful rendering capabilities, including Cycles for realistic reflections and lighting effects, you’ll see how to make your 3D models look as if they naturally belong in the 2D image. Additional steps include using HDR images for improved ambient lighting and fine-tuning shadows to enhance the composite’s realism. Whether you’re a beginner or an experienced Blender user, this tutorial provides invaluable insights into creating stunning, photo-realistic scenes by merging 3D and 2D elements.

Happy 3D modeling!
