Consider:
- skipping the PMC and
vInterpTo
to target (or the constant variant) - skipping the PMC and Timeline
Lerp
to target (you could even dynamically spawn a spline and drive projectiles along an elaborate path) - using the PMC Homing Target while also nudging it with physical forces (may not always hit, though)
Rotation can be obtained in many ways. For example: Find Look at Rotation
using the projectile’s location from previous frame and the projectile’s current location.
If you want something truly performant, since we may be talking about 100s of projectiles* (right?), look into Niagara.
