The early filming went well, and the scheduled time was much earlier, so Tang An was not in a hurry to rush to Xiangjiang immediately.

From the preliminary preparation to the present, the crew has been exhausted by several months of busyness, and it is just the right time to take a break.

On the morning of the 9th, Tang An came to the post-production center of Huairou Film and Television Base to inspect the production of film special effects.

Generally, the pre-production and post-production of a film are separated, and some scenes do not have to wait for the finished film to come out, and the production can start first.

I was still sleeping at my desk last year, and in more than a year, it was the third movie.

At the bottom of the building, Chen Yanjun, the director of the production center, was already waiting there, and when he saw him coming, he immediately took two steps forward and greeted him with a smile on his face.

"Director Tang is here!"

"Director Chen hasn't seen me for a long time, this time let's see how the special effects are doing, you won't bother me!" Tang An laughed.

"No, no, how can this be, many places have to wait for Director Tang to come up with an idea!" Chen Yanjun hurriedly said.

Just kidding, the post-production special effects are equivalent to 20 million yuan, and their entire post-production center can't receive a few such big orders a year.

Although they didn't get real money, in addition to allocating a production fee, China Film also gave them quite a generous bonus!

As a small subsidiary of China Film, a huge entertainment group, it has been unable to make ends meet before 04, and even most of their main business is not to make movie special effects.

TV series, TV movies, cartoons, commercials, ......

Basically doing everything, there is very little time to actually do the special effects of the movie.

That is, starting from Tang An, three movies in a row, not only turned their center into profits, but even the appearance of the entire company was different.

At a price of 20 million, you must give people an effect of more than 20 million, which is no better than those producers who are only willing to take hundreds of thousands to fool the audience.

"Director Tang, come in, the model of the car chase scene has been prepared, the digital painting extension and CG background extension of the entire Xiangjiang have been made, simulating various automatic CG weapons, in order to ensure that the picture is real and credible during digital synthesis, it is completed at ultra-high resolution......"

Chen Yanjun introduced Tang An as he walked.

"Director Chen has a heart, of course I am relieved to leave these things to you professionals, this time I will take advantage of my time to take a look!" Tang An nodded frequently.

Walk through the building and come to the open space of hundreds of square meters in the back.

The original vacant land has been arranged into a miniature version of the Beijing CBD business center, and a team of hundreds of model makers is holding photos and measuring tools to compare them in various places.

More than 10 special effects experts in the center are constantly drawing and recording data, and under their feet are all kinds of vehicles, including police cars, joint ventures, domestic and other cars.

"Bang Bang!"

Chen Yanjun clapped his hands and gathered everyone together.

"Come here, Director Tang is here to inspect today, everyone must prepare well, no one will drop the chain at the beginning of the meeting, and show our technology to Director Tang!"

After that, he whispered to Tang An, "Director Tang, do you want to say a few words?"

"No, everyone is professional, I'm just here to see!"

It is worthy of being a state-run institution, and it speaks at every turn.

After the disbandment, Chen Yanjun began to explain one by one.

"Previously, our VFX DP had taken 360-degree HDRI images of several locations and scanned the LIDAR scene to provide accurate and detailed data. ”

"The combination of HDRI and LIDAR scanning is very important, every parameter may affect the entire model production, I think you have done a good job of this, it is simply a condensed version of CBD!" Tang An nodded.

Through the first two cooperations, Chen Yanjun also knew that Tang An had a certain understanding of special effects production, so he didn't dare to be careless, and did his best in every place.

He continues, "We also simulated the dynamics of the car rigs to get the suspension system right. ”

"Once each car model is selected, we run simulations on high-precision ground models scanned by LIDAR, which can track points on the ground and collisions that match the weight and specifications of each vehicle.

"For all car collision screens, we developed a deformation rig system that can control the deformation of the geometry mesh based on the impact point, velocity and angle. ”

"We started with the most basic deformations and refined them with more detail, including simulating the interior of the car that would be represented, and adding a second layer of animation. In addition, we also simulated special effects simulations of small elements such as debris, dust, smoke, etc. in Houdini. ”

Chen Yanjun turned his head at everyone as he spoke, "Old Wang, are you ready for the lighting treatment of dust and smoke?"

"It's ready, I've experimented many times, and I'm sure it's okay!" a middle-aged man in the crowd raised his head and replied loudly, and then went back to his own business.

Once you've turned everything around, it's time to start testing.

The staff tied the cars to Weiya, and the first shot was affected by superpowers, the two cars collided head-on, and a police car on the side happened to collide with the two cars.

Three cars collided, and the special effects photographer had to shoot from all angles, and two rocker cameras shot from the top of the air.

The special effects are complex and detailed, with every detail carefully calculated, from the direction of the collision and deformation of the three cars, the vibrations that occur, the dust around them, and the range and rate at which the car parts fall.

After watching them shoot twice, Chen Yanjun took Tang An to the office.

There is a scene in the film with a beautiful view of the Xiangjiang River from a hotel suite.

This is not a real shot, and the on-site shooting cannot achieve such a perfect night scene.

Chen Yanjun pointed to the computer screen and explained, "Our photographer spent six days shooting a lot of high-resolution twilight and night scenes of the Xiangjiang River. ”

By compositing these negatives to create an ultra-high-resolution animated panorama, the senior digital painter added tall buildings and neon accents to the scenery to make the scenery layered. I went on to build a 3D digital painting to make the building parallax effect in the foreground and middle ground very realistic!"

"The effect is very good, but you can't achieve this effect if you shoot it in real time!" Tang An nodded with satisfaction.

"And here!"

Chen Yanjun led Tang An to another LCD screen, "This is the colorful rays and the X-rays of the heroine's superpowers that we made according to Director Tang's requirements!"

"There are also some "invisible" things that the heroine can see, and we started to divide the actual footage into different levels, similar to the operation during the stereoscopic transformation. ”

"Once we decided on the layout of the different levels of depth, we replaced the layers with elements that were shot against a green background. These "invisible" scenes, such as hospital corridors and examination rooms, were then modeled based on LIDAR's scans and projections using simple geometry combined with projections. ”

Finally, we animated the elements in three so that we could switch between live-action and X-ray effects. THESE EXTENDED SCENES AND CG CHARACTERS ARE RENDERED WITH DIFFERENT MATERIALS, AND THEN COMPOSITORS COMPOSITE THEM TOGETHER IN FLAME WITH ARTISTIC TOUCHES. ”

......

In the next few days, Tang An went back and forth between his home, studio, and base.

Until the afternoon of the 14th, Tang An was invited by Han Sanping to attend the world premiere of "Wuji" in the auditorium of the Chinese People's Political Consultative Conference in Beijing.

Just get acquainted with more contacts, and this is the second time he has seen Han Sanping in a few months, and there are still many things to discuss in the later publicity!
