Chapter 1047 Even if it's bad, there is still a company to take care of it
In front of the main control screen of Tiancai Special Effects, Guo Fan was sitting in the command chair, his eyes fixed on the clip of "The Wandering Earth 2" playing on the big screen.

In the picture, a huge planet is slowly approaching the earth in the dark universe. As the sun collapses, the details of the hot magma flowing out of the cracks on the planet's surface are as clear as real.

"This is the shot of the planetary impact," Guo Fan said solemnly, pointing at the screen. "The problem now is that the flow of the molten lava is not realistic enough. It's too regular. It should be more violent, like a wild beast out of control. Also, the rendering of light and shadow here."

Guo Fan swiped his finger across the screen. "The transition between highlights and shadows when the molten lava gushed out was too rigid. It lacked a sense of reality."

At this time, the special effects engineer sitting next to him immediately opened the parameter panel and said, "Director Guo, we are currently using a standard lava effect based on fluid mechanics simulation, using OpenVDB volume rendering to simulate the heat flow and convection caused by temperature differences.

But if a more violent effect is needed, we can try adding a turbulence disturbance node to make the surface liquefaction details more fragmented and dynamic. "

"What is the parameter control range of turbulent disturbances?" Guo Fan asked.

"We can superimpose a more complex vector field on the velocity field to increase the sense of chaos," the special effects engineer said as he operated. "But this will increase the calculation time, especially at high resolutions, which may double the rendering time."

Guo Fan nodded. "I'm not worried about the rendering time. This is the visual climax of the movie. We must give the audience a sense of shock as if the sky is falling and the earth is collapsing. If necessary, the model can be further optimized."

Just when Guo Fan and the special effects staff were discussing enthusiastically, Li Mu walked over, but the two still didn't see it. Instead, the other special effects staff saw it, but Li Mu just pressed down slightly with his hand, nodded and smiled.

There's no need to say hello in this kind of situation, just get to work.

Li Mu walked over, glanced at the screen, and asked with a chuckle, "What did you talk about?"

"Senior Brother!" Guo Fan turned around and quickly stood up. Then Li Mu gently pressed his shoulders and asked him to sit down.

"Mr. Li!"

The special effects engineer called out quickly.

"It's okay, I'll just take a look."

"Boss Li, we are adjusting the special effects of the planetary impact segment. We are currently discussing the issues of molten lava flow and light and shadow rendering."

Li Mu walked closer to the screen, carefully looked at the picture twice, and frowned slightly, "Indeed, the molten lava looks like it is controlled too steadily and lacks a natural sense of power.

There are also problems with lighting and shadows. Now it looks more like game CG than movie special effects. Is it because of insufficient funding?"

Li Mu wondered, "The Wandering Earth" should not be short of funds.

The special effects staff scratched their heads and explained, “Mr. Li, our current solution already uses physical rendering, and the refraction and scattering of light are simulated based on the real behavior of lava.

But there may be a lack of ambient light interactions, such as the effect of lava on the surrounding dust and air."

Li Mu thought for a moment and came up with a possible solution. He was about to speak, but stopped himself. He glanced at Guo Fan who was sitting there thinking hard, and remained silent for the time being.

The main thing is that he is no longer the director, and if he speaks in front of the special effects staff, and if his opinion disagrees with Guo Fan in the end, who should he listen to?
There's no need to make suggestions here. After all, Guo Fan still has to stay with the people here for a few months. It's difficult to establish prestige and other things, but it's easy to lose them.

Moreover, he believed that Guo Fan would not be unable to handle such a simple problem, so he just supported himself on the edge of the chair with his hands, stood behind him, and said nothing.

Guo Fan thought about it for a while, and his eyes lit up slightly. "Do you think this will work? Ambient light is a starting point, and the flow of the molten lava itself needs to be more emotional. But the movie is not about replicating reality, but about shocking the audience. Use the particle system to enhance the splashing effect of the molten lava, especially the moment when it hits the earth, so that the blending effect of the molten lava and dust will have dramatic tension."

"Another point is that the impact of the shock wave from the collapse of the sun could be even greater. When this shock wave passes through the magma, there should be an effect where the high temperature causes the gas to expand, such as the ripple effect of the magma being pushed away by the airflow." Li Mu nodded slightly at the back. The plan was similar to what he thought.

I have to say that as a director, after spending a long time in various departments, you basically understand the "rules of the trade" of other departments to a certain extent, which makes you an omnipotent person.

It can be said that you may not be proficient, but you cannot be ignorant, because when you don’t know, you cannot fully describe the effect you want to the special effects engineer. What the other party produces may not be exactly the same as what you have in your mind, so a lot of time will be wasted arguing.

The special effects staff quickly opened a new effect layer. "This can be done with fluid particle diffusion to simulate heat diffusion caused by high temperature, and nodes can be used to control the dynamic range of expansion and bursting. But in this case, we need to adjust the lighting of the entire scene and increase the reflection of global light."

Hearing this, Li Mu smiled and patted the two of them, "No problem!"

After resolving the matter, Guo Fan and Li Mu sat down on the sofa.

"How is it? Is the progress ok?" Li Mu asked with a smile.

"We will definitely be able to make it in time for the Spring Festival. The only thing I'm worried about is the quality. After all, you are such a great example."

"You're afraid of nothing." Li Mu scolded with a smile, "The entire Mengying Media is behind us. Even if things go wrong, the company will take care of it."

"Hehe, thank you for your support, senior brother." Upon hearing this, Guo Fan quickly responded with a smile.

"Okay, get some rest!" Li Mu patted his shoulder before leaving. Recently, Guo Fan was almost living here as if he was risking his life.

As soon as Li Mu left, Guo Fan immediately sat next to the special effects engineer.

"Director Guo, didn't President Li tell you to take a rest? Nothing will go wrong here, don't worry." The special effects crew looked at Guo's film and said with a smile.

"It's okay, I'll just watch."

"Boss Li, just before leaving, I told you to get more rest. You..."

"It's okay, just don't argue with Mr. Li. Just do your thing and I won't get in your way."

"Director Guo, he is the boss!

"."

When he went out the door, Li Mu took out the car keys.

As for the autumn evening glow of the imperial capital, I had no intention of appreciating it.

Although the glow in the sky at this time is like splashed paint, with different shades of orange, red and gold interweaving into a magnificent picture, as if the entire sky is on fire, such a beautiful scenery should not be missed.

But going home is more important.

The leaves of the ginkgo trees on both sides of the street have turned slightly yellow, and the light of the setting sun shines obliquely on the car, casting mottled light and shadows.

Li Mu stepped on the accelerator and drove back home.
