Rendering is the last step before entering the post and the last opportunity to adjust the effect of the picture in ue. Before rendering, we often do some rendering Settings.

First of all, we can adjust the post box, which is to control the overall effect of the screen, which can be understood as a filter. It can change the color of the light, the overall exposure compensation, as well as the screen color control, lens halo, etc., there are a lot of parameters that can be adjusted. I simply adjusted some of the exposure colors and temperatures, and for some of the details of the more complex channels, I will gradually try to understand them in future projects.

Programming command is also a very important part, he can use commands from the direction of programming to control the screen effect, this picture is my notes recorded some of my more commonly used expressions.

The last and very important rendering setup we have I am used to changing the output sequence to Png sequence and adding the resist tooth effect. Set the frame count to 30fps and the screen size to 2640*1080

For better visuals, I decided to add nigara system to my ue project. I plan to make some firefly particles to enrich the effect of the picture. At the same time, this is also an initial attempt, and I hope I can use it in future projects

First I created a material that can be applied to fireflies. This is a dynamic material, with particle color and some radial gradient node composition of the material, while some coordinate position, subtraction, multiplication and other calculations, and mapping to create an uneven particle state

After making the material, it was time to create the particle system. I used the base template emitter of hanging particles and adjusted the base material to give this example the material I made in the previous step.

The most important thing is that the base color of the particle needs to be turned up at the value to be greater than 1, and the particle will produce a luminous effect, which is exactly what I want to do for the firefly.

After doing this, I found that these particles were a little lazy, and their moving speed was very slow, so I added some flow nodes to the wind speed to flicker the number of speed scale color RGB nodes, which could be adjusted to its maximum and minimum value.

The result is an example that I am satisfied with.

Just Body animation in maya is not complete, another reason I use metahuman is because of face capture.

I use Live Link Face, which can be well connected with Apple’s mobile phone to implement real-time face capture, link to my mobile phone, and use the camera recorder to capture facial data, and finally apply it to my character model with blueprint.

This is a note I made, which records a lot of details about how to link plugins

For every beginner, understanding the workflow of the software is one of the first and indispensable key steps.
In my initial vision, I wanted to get the character model through ue’s metahuman plugin, complete the animation part in maya, and finally bring the animation back to ue to make the final effect and complete the rendering.

What’s frustrating is that I have a lot of trouble trying to work with the workflow, I try to find tutorials, I try to make mistakes, and then there are still some problems that don’t get solved well.

Today we are using metahuman to create facial animations from videos we shot ourselves. We used metahuman and live link plug-ins to achieve sequence recording, action baking, animation transmission, and finally realized the effect of face capture. It was a bit off in terms of accuracy, but it was a very interesting experiment

In this lesson we learned about high resolution screenshots and rendering Settings, as well as the post box to control the scope and quality of the rendered picture. Use anti-aliasing methods and commands to improve the rendering quality.
