VFX Welding - UE4 -

Path to Learn RTVFX 2
The aim here was to make a vfx from scratch in UE4 using Niagara Sytem in a more realistic environment
Lot of thanks to @StevenCheung who motivated me and helped me (and is still helping me) along this path.

Disclaimers :
At first, it was made with UE5. But the scene happened to have a lot of issues.

- Light and Reflections : A lot of flickering, uv offset different meshes for unknown reason, lighting persistency even after the lightsource was deleted. After a certain among of time working on it and some unsuccesfull attempts to repair it. I resolved myself to start fresh with the same scene but using UE4 (and to check at every step that the scene was not broken).

In the end, I'm still not able to determine if theses issues were inherent to the scene I used, or to UE5.

Some issues are still persisting in this scene :

- The animation made here are not my doing. They were included and unfortunately there are some issues. The industrial arm are either too far from the engines they are suppose to work on, or too close (colision with the other meshes).

I try to choose a point of vue that can hide a bit of these issues. That's why the point of vue for showcasing the VFX is not that great.

Create new sockets for the VFX in the mesh skeleton (1) and placing it where the vfx is wanted (2)

In the Mesh Animation, I have created 2 new layer tracks and I added my Particle System as a Advanced Timed Niagara Effect (1). Exact same process done for the others animations (2)

Integration the Particle System was a bit different here. In the RobotArm Blueprint, the particle Effect was added (1) and the previous existing one was deleted.

Then, in the event Graph, I simply replace all nodes referring to the old Particle System by mine (1).
