Flow map and SubUV for Particles

Hi,

I’m wondering if there’s is a way to create material and use the flow map workflow with Particle SubUV.
I tried to simply plug into the UVs input of the Particle SubUV node, a Lerp node between the default texture coordinate, and the distorded one. But when I change the alpha value of the lerp node, nothing seems to happen.
I also tried to replace the Particle SubUV node instead of the texture coordinate and flow map, with no result

However, I tried to do the same thing with a texture sampler node instead of the Particle SubUV one, and got the result I expected.

Is this a limitation with the Particle SubUV? if so, what is the purpose of the UVs input in this node? Thank you a lot for your help

Hmm interesting, posted in hope someone replies and allows me to read it as well.
