#modularrig

Unreal engine, known as one of the best game engines, is evolving with every update. While working on my project, I had problems with the character. There was no control rig present, and I was unable to generate a quick control rig without the tools creating their own skeleton.

Unreal Engine, in its latest 5.4 version, released a new feature called Modular Rig. It is a life saver especially for people who need a control rig inside of Unreal Engine and get their work started without manually rigging.

Using the modular rig is very simple. You simply right click on the skeleton mesh, go to animations and in the bottom option, select control rig. Then select modular rig. This takes you to the modular rig section and all you have to do is to drag and drop the icons to create a control rig.

This above is the tutorial by Smart Poly that I followed and was able to get my work done.

After searching for some time, I found out that in the new version of Unreal Engine 5.4 uses a new feature called the “Modular Rig”. It takes the characters bones and asks you to tell the tool where what bone is. After assigning the bones, the tool automatically creates an unreal engine control rig.

The modular rig did create the control rig. But even then, there was a problem with the mesh. I was unable to move the hands using IK rig. The rig was only FK. The mesh breaks whenever I tried to move the part of the body, there were no constraint attached to him.

I sent this to Malcom, our rigging teacher, and he showed me how to switch IKs and FKs in this modular rig. There were some naming problems with the bones which he fixed for me and made my work a lot easier.

Above is a screenshot Malcom sent to let me know how to switch between IKs and FKs.

I also asked and found out that I cannot import control rigs from Unreal Engine to Maya (or vice versa), so I was unable to animate it in Maya. Since I have already spent a lot of time on this, I decided to just animate inside of Unreal Engine using the sequencer.
