Cinemachine Transposer smooth zoom. Help please

Hi guys

I`ve been using cinemachine for quite a while and it is AWESOME literally in any mean. The only addon I am using and it is worth.

However, without further chatter i want to explain the problem I have, it is simple one i guess but i can't find the proper way to do it. I am making 2.5D game - sidescroller, going left and right only, so far I got everything under control, the only problem i have is I cant make the zoom functionality to work smoothly, it works, but the transition is very fast and i need slow transitions.

I am using only 1 camera attached to the main character which is following him everywhere. I have referenced parts of the cinemachine code/transposer functions to an invisible blocks(trigger) through my map and once the player collides with it, it updates the Vcam values with the new ones from the colliding block.

For the zoom function I am trying to manipulate the "Camera Distance". I have also tried playing with "Field of view" setting so i can zoom, but the result is the same, the zoom transition is happening very fast.

I have noticed that when dragging the "Camera Distance" field, the camera is transitioning smoothly, but if I write a number inside the field the transition goes very rough and fast. So please help and if someone can explain me how can i use the "drag" transition (if possible) which smooths out the zoom, or is there other feature that can be accessed through code?

Thank you.

So i am using this setup for the main camera:


I am using this setup for Vcam1:

 

Thank you for the help, i had troubles before writing lerp function code, it wasn't working (probably i did some wrong things, i`m still learning programming) but thank you for the idea.

Update:
I followed your idea and actually i made it. THANK YOU!!!
Here is what i did, pretty simple (if i could knew this before), it is working:

zoomLevel -> value that i add in the inspector manually

if (transposer.m_CameraDistance < zoomLevel)
{
transposer.m_CameraDistance = transposer.m_CameraDistance + Time.deltaTime;
if (transposer.m_CameraDistance == zoomLevel)
{
return;
}
}
else if (transposer.m_CameraDistance > zoomLevel)
{
transposer.m_CameraDistance = transposer.m_CameraDistance - Time.deltaTime;
if (transposer.m_CameraDistance == zoomLevel)
{
return;
}
}


I also wrote custom code for rotation for cinemachine camera and works like charm. I`m sure this will help many people as well:

targetRotation = value that i add in the inspector manually
rotateVertical = the angle Y i add in the inspector manually
rotateHorizontal = the angle X i add in the inspector manually
smoothing = multiplier of the movement, i add in the inspector manually

void Update()
{
targetRotation = Quaternion.Euler(rotateVertical, rotateHorizontal, 0);
transform.rotation = Quaternion.RotateTowards(transform.rotation, targetRotation, smoothing * accelerationValue * Time.deltaTime);
}



Thank you once again
