Any tips for doing such a thing?

Also did new Set * Pin modules help in this case?

if yes, how to use it?

Hi Ahmed,
Yes, with some hacking you can use a Set Pin module for that.
Add a Set Integer Pin beside your pin collector.

In order to set the pin you have the specify the exact module name and pin description of the collector:

Set Value to the desired initial value.

Now you want to trigger the Set Pin module exactly once when the scene starts.
It can be done using a Timer with a small End Time,  for e.g. 0.1 seconds.
It also have to be put in Play state.

this solution work but any plans to simplify the process ?

And If we have pin collector with multi input how we can set these input to defaults ?

Hi Ahmed,

For multiple inputs you simply have to connect multiple Set XXXX Pin modules the Timer and specify the correct pin name for each of them.

Currently the only method that is simpler than this is paying attention that the values are all in the desired position whenever you save the scene.
