This a really basic tutorial for R6 and R15 on how to noclip. Some R15 avatars are better to noclip with than others, although nothing really changes in R6. Videos are at the bottom.
R15 Tutorial
Depending on how far your emote goes is how far you can noclip. I cant cover every emote but here are some emotes and how to noclip with them.
V-Pose. Walk up to a wall and turn backwards. Hold "S" Until you touch the wall. Do V-pose turn your camera sideways. And press shiftlock.
Baby-Queen Walk up to a wall. Turn backwards. Use your emote. When you go fowards turn your camera 180 Degrees. Then Press shift. (Same Steps as TWICE Like Ooh-Aah)
R6 Tutorial
Unlike the R15 Tutorial your avatar does not matter on how far you can noclip. There are 2 Well known methods I prefer the Laugh Lag Clip because it goes farther.
/e dance2 Walk up to a wall. Turn your camera sideways. (90 Degrees) Type /e dance2. When your avatar jumps to the right press shift lock and Hold "D" (0.1-0.9 Studs)
Lag Laugh clip Walk up to a wall. Turn your camera 90 Degrees. Do /e laugh. When your head goes back Tab glitch. (Tutorial on https://discord.com/channels/1143867106765570088/1232786227896389732 ) While Frozen Hold "S", "Space", and "Shift." Then Unfreeze (0.1 - 1.1 studs)
