Finally, I have a short free time to summarize the quick smoke tutorial that I found in the previous rendering process, hoping to enlighten your thinking.

This is the final effect display, the smoke is all surface, so the rendering is very fast.

1. The breakdown of lighting, in fact, lighting is not very complicated, I personally don't like to play a lot of light, on the one hand, it is not convenient to adjust, on the other hand, it will appear messy.

2. The effect of all light on.

3. We add a plane to the back and adjust the highlights and diffuse reflections to black.

4.(Possible Problems) When returning to the main viewing angle, you will find that the outline light of the object has disappeared.

5.(Solution) Pull the black plane away from the product, or reduce the black plane to make it only a little larger than the camera's viewing angle. It's important!!!! Most of the time, objects outside the camera block the light, so it is not right to light up. (Speak words: simplify all objects outside the camera's perspective)

6. After adjustment, the light is normal

7. Add ground and a plane.

8. Add opacity and refer to mottled light and shadow for connection mode.

9. Add bottom smoke

10. Gradient Map

11. The black part is transparent

12. Without adding color compound, the places on both sides that should be transparent will become opaque.

13. The output source in the color to be counted controls the transparency on both sides.

14. Like the bottom smoke, add a flat surface to make a lamp near the Tindal phenomenon.

15. Returning to the main perspective, I found that the smoke volume sense of the light part is not strong.

16. Add a very narrow lamp to the upper left corner of the smoke in the light part to make the smoke feel gradual.

17. Back to the main perspective, I feel much better now.

18. Similarly, adding a small area light in front of each lamp is done.

19. To sum up, this way is biased towards ps thinking, which can make medium-quality smoke effect simply and quickly. Let's learn and improve together O(∩_∩)O ha ha ~.

Hey, hey

我也说一句

I thought it was ps. I didn't think it was rendering.

It may be more convenient to use multi-layer VDB.

杨晓作者 2020-08-12

you can try it. my feeling is that it is more troublesome to find a suitable vdb file, and it takes a long time to simulate with blender or c4d (my current ability). To achieve the same Tindal effect will require more strong light probability will affect the light. The most important point is that I need a better computer, which my 4-core computer cannot afford... The rendering time is very long and the noise reduction of ks is too chicken ribs now. Simple planes can be drawn quickly, and yan fog's materials are relatively easy to find. Of course, after I change my computer, I will definitely try more deeply. Thank you for your valuable comments

My goodness, you are still using quad-core . I have never used a picture for keyshot noise reduction. it feels so strange, just like PS beauty

Yes, gpu mode is not very mature either. It is estimated that the next version will be better.

I tried to stack four VDB, and the picture showed strange black edges and deformation.

After turning on the noise reduction, it will be much better when it is buffered and shaded for a while,

It is true that VDB is a simple and easy-to-use method, but it is a bit unfriendly to light up. C4D does a lot better. If it is keyshot, it is better not to use noise reduction and GPU. Many strange bugs seem to be much better after 9.3. However, I still dare not use noise reduction.
