Hi all! Ive been lurking around the forum for a while and seeing some amazing stuff, but now Ive finally plucked up the courage to start my own sketchbook and post my progress as I grow my skills and understanding of real-time VFX. I have a degree in games art and design, but only in my final year did I decide Real-time VFX would be my niche so my skills are still beginner. Im currently learning through VFX Apprentice courses for the next year to see how far I get. Cant wait to grow with you guys!After a lot of tutorials, Im stepping out of my own (a bit) to test what Ive learned. So, Ive started a block-in version of the magical trails from Darin Aranda substance designer course on VFXA. Its not been as straight forward as I thought, but Im happy with todays progress.All of the movement is in the rotate around point module. to distribute the two particles evenly, I changed the rotation phase to return normalized Exec Index (thanks to CGHow for that) and unchecked normalized index included. Set rotation rate to above 1 to get them going.To get the orbs to fly in a up and down a bit, I went into the rotate around point module, made the x-axis into a vector and animated the z-axis with a sine-wave. I tried a lot of different things and this was the most straight forward in the end.However, there are a few things Id like some insight on. Firstly, the sine wave works, but when the system restarts its loop, the wave kind of restarts, as in theres a jitter when it restarts. In the level its fine but Im wondering if there is a simpler more seamless way to get them to move up and down.Second, I see this at the start of the system:Which makes me think the orbs spawn in the middle and quickly move out and the trail follows. It doesnt look very clean, so again Im wondering if theres a better way. Can I delay the trail spawning in by a bit so that this doesnt happen?Feedback welcome!
