I`ve followed the tutorials and i have at arrived at a point that i think it should work but it doesnt.
houdini vex code (should be irrelavent since i cant even get anyhting in)
// Convert angular velocity to quaternion delta (per second) float angle = length(v@w); // radians/sec vector norm_axis = normalize(v@w); vector4 q = quaternion(angle, norm_axis); // builds quaternion from angle+axis vector4 unrealQuaternion = set(q[0], q[2], q[1], -q[3]); // note that someone said that // set(q[0], q[2], -q[1], q[3]); //is what actually worked for them p@rotvelq = unrealQuaternion;
Sometimes i also get HoudiniNiagaraBasic Particle Span Script interpolated. I dont know where it comes from or how to remove it.
there is no toggles on the emiiter spawn and there is no toggles on emitter state i havent toggled.
I imported with the the hjson.
