Use tools: VRED HDR Light Studio PS is busy, and another year is almost over. I faltered to learn VRED and bought Yuge's book in 2019. Since then, I have started my study of rendering. I also learned the last exercise intermittently. To tell the truth, if you do it completely, the biggest change may be when you look back at the previous works like shit. I know I have made progress, but it is far from enough. I still need to study harder. The biggest gain is that we must dare to take the first step and then stick to it. Taking the first step and insisting is what this book has taught me. There are still many flaws in this work that need to be pointed out, and I will definitely learn with an open mind. For the rest of this year, continue to strive for by going up one flight of stairs. Welcome everyone to pay attention to our public number "UK Design". We will update the rendering and modeling tutorials from time to time. I wish everyone a happy holiday in advance.
