本文针对室内设计效果图制作所使用教材中制作流程不够合理、导致出图速度慢等问题，提出了优化效果图 制作流程的解决办法，包括导入CAD图纸、改变材质和灯光的设定顺序、针对灯光和材质分别测试、使用光子图加快出图速 度、将正式出图的TGA格式改为质量更高的TIF 文件、用转换插件生成材质通道图等，有效提高室内设计效果图制作的速度 和质量，使学生掌握实用性更高的制作方法，提高了教学的效果。

In view of the problems of unreasonable production process and slow speed of drawing for interior design, this paper puts forward a solution to optimize the production process of drawing, including importing CAD drawings, changing the order of materials and lighting settings, testing the materials and lighting, speeding up the drawing speed using photon map, transferring the TGA format into TIF file, and generating material channel drawings with the conversion plugins. The solution effectively improves the speed and quality interior design drawings, makes students master more practical production methods, and improves the teaching effect.
