[SOLVED] - CHANGING THE BASELINE

[nalinraut]

I am re-opening a new issue since I have no response on the other issue and eventhough this particular issue may be a solved one, none of the solutions are working for me or I might be going wrong somewhere, however, without any response it is getting a bit difficult for me to carry on with my project.

Following is what I tried for changing baseline:

( a) I edit BP_FlyingPawn using UE4Editor as suggested in #1770 (comment).

(b )Next, I save, build, and compile in UE4Editor itself. I close the UE4Editor and reopen it to find no change in the baseline.

Left Camera in BP_FlyingPawn:

Right Camera in BP_FlyingPawn:

The images retrieved from Front RIght, Front Left, and Front Center, are evident from snap below.:

Like both Left and Right cameras are 2006 units apart.

The settings.json file I used is:
{ "SettingsVersion": 1.2, "SimMode":"Multirotor", "SubWindows": [ {"WindowID": 0, "CameraName": "1", "ImageType": 0, "Visible": false}, {"WindowID": 1, "CameraName": "2", "ImageType": 0, "Visible": false}, {"WindowID": 2, "CameraName": "0", "ImageType": 0, "Visible": false} ] }

I would really be glad to have this issue solved.

can you click save and compile in the flyingpawnBP window itself? that works for me. You'd need y=-6 and +6 for left and right cams for ZED.
Y=20000 is def a crazy value, and if got saved, it means you did it correctly once.

@madratman Thank you for the response. I could save and build it in the UE4Editor window, however, when I play without closing Unreal, Unreal just shuts off/ crashes. And when I reopen it, even though the value is saved, it is not being used. Also, at y = 20000, I get to see the same image as seen at y = 25. The values are definitely being saved but not used.

My earlier answer in this comment - #1770 (comment) - was way too complicated.
You don't need to mess with blueprints, the baseline / camera poses can be changed from settings.json itself.
Instead of centimeters, use meters. So it will be Y=-0.06, and Y=+-0.06

@madratman Thanks! This works.
