<html><head><meta http-equiv="Content-Type" content="text/html charset=us-ascii"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">Hi Gottfried,<div class=""><br class=""></div><div class="">it's not a huge problem, but we basically have to spawn all articles for a single time-step around the emitter region. So for the distance "timestep * inflow-velocity" we have to create enough FLIP particles for a continuous stream of liquid without gaps. When the object is not planar, that will be "messy", and not lead to a proper inflow. Is there some convenient way in the blender UI to input a direction? Then the inflow could consist of a volume defined by a mesh plus an inflow direction...</div><div class=""><br class=""></div><div class="">And you're right, it would be cool to have finer control over the inflow velocity with textures.</div><div class=""><br class=""></div><div class="">Cheers,<br class=""><div class="">
