Hidden tyFlow object perfrom simulation on render stop with Corona only

[v.p.vlasenko]

Hi,
problem - clean scene, simple tyFlow object is hidden (as simple as birth operator only, so it won't render anyway), changing frame to let's say 50 doesn't perform simulation, starting render (interactive or production) as well doesn't perform simulation, but when I stop or cancel render, tyFlow start simulation up to current frame (50).

tyFlow objects simulate their result when Max queries their base object for a result

...

hiding a tyFlow object does not guarantee Max will never query it.

I tried Arnold and Scanline - no sim on render end, so probably some problem with Corona?

Hi,

I am unable to repro this on my end using 3ds Max 2024, Corona 12 HF 1 and latest version of Tyflow. Is this happening in some specific sim you are doing or this is happening even in a very simple sim also?

Is it possible for you to send your scene file so we can investigate this further?

you can send your scene by starting a ticket here: https://support.chaos.com/hc/en-us/requests/new

Hi,

I noticed it in a specific sim, but when I tried to figure out what's going on I found that it happens in such a way in the simplest scenes, like in the video below

I don't think I need to send such scene to you.

I forgot to add my specs in the original post:
2025.3
latest corona daily
tyflow 1.118
