Hello everyone :wave: Inside my shader I am passing a uniform vec3 direction to periodically offset the vertices positions, like so: // Pars uniform vec3 direction; // passed in normalized uniform float timeElapsed; ... // After #include <begin_vertex> transformed += direction * sin( timeElapsed )…

Turns out the correct way to do this is to multiply not by the matrix but the inverse of the matrix
