Showcasing the use of simple math and some smart 3D techniques to fake volume on effects. The speakers go over the tricks to create a volumetric Laser Sword effect in Unreal, using Niagara to control visual properties of the material and to pass position and rotation data to the shader to achieve a smear effect while keeping the volumetric glow around it. Also, this sessions explains how to use Dot Product and Cross product to control the rotation of 2D particles inside Niagara in a way to fake a twirling motion of dust in the wind. As a result, the left side of the ring to rotate to the right, the right to the left and the center won't rotate at all.
Attendees will leave with a better understanding on how to fake volumes with planes using shader tricks, and how to use position transformations and interpolation to create a smearing effect on a mesh, and some basic Niagara workflows to put the whole effect together. Other than that, attendees will understand vector math a bit better, being able to do separate rotation behaviors based on the position relative to the camera.
Intermediate Realtime VFX Artists looking for insights on how to use vector math and transformations on their shaders. The talk is mainly focused on covering the math used inside the material, which can be insightful not only for Unreal user, but for any other Engine as well.
