Problem

Description:

Heya,

When lowering the substeps, particle flow particles are losing too much speed, up to the point where they barely exit the emitter and just drop under it.

Steps to Reproduce:

Thank you, I will have to check it out.

I wasn't able to reproduce this, have you tried it in a newer build?

Hello Marsel,

Apparently 'no'. The number of substeps doesn't seem to cause this issue anymore :)

However the speed operator in PFlow is still ignored it seems, you need to use the Lucid global settings 'max particles velocity'.

The speed operator should be taken into account, but Lucid will limit the speed based on the global setting. This option is to introduce stability in fluid simulations.

Further testing showed that in fact it still happens, but a bit less, with less substeps particles loses velocity.
