tyuvwfreeze not working back

[Booclay]

Hi all,

I have TY pro and have cached some particles then uvw mapped them then applied a tyuvwfreeze at frame 120. It sticks the texture at 120 onwards but not backward in the simulation. What could I be doing wrong?

Many thanks in advance

Is your particle count changing? Topology can't change for the modifier to work.

yes the particles birth over a time period, but I thought that was ok?

like the person does in this tutorial:
