Hi

I've been playing with multiple cameras as well, recently, and I'm a bit puzzled by one problem. The code I've added here is a test with four cameras positioned and rotated exactly the same way, and set up to be exactly the same image size, and the same fov.

However, camera 1 (the one in the top right of the screen) has a different fov to the others, it looks like it's a 4:3 ratio image, like the screen resolution, while the other three are 1:1, square.

Could someone please try the code and tell me if they get the same effect? I've tested this with 12 cameras and it's the same, all of them eccept #1 are square.

Thanks

Avan

Ah, it's attached the code as the 'source' button at the bottom of the above message.

Yes, I get same effect but do not see why it is happening. Played with code for a bit but can't fix it. Must be yet another bug!

I've found a solution to it, it always happens on the first camera created, so to solve the problem, create all the cameras you need, plus one extra, and delete the first one you made. Seems to correct it.

Wonder what causes it. Seems like an odd nature for a bug. *shrug*

prolly a fov command setting

try the camera fov setting tutorial and perhaps it will work for all cameras created.

Indi - I have played with the fov command and it seems that the first camera created has a 4:3 ratio image, so changing the fov doesn't help because that changed the fov of both the vertical and horizontal view, now if DBP had control to change both, that would be able to sort this problem, I believe. Thanks anyway.

Also, does anyone know why the 'set camera to image' command is so restrictive on the image sizes, you have to use computer numbers, 64, 128, 256 etc, so you can only make images of 1:1, 1:2, 1:4 etc, I was hoping to be able to control the exact size of the image, or am I wanting too much?

The camera problem I have also had.

The image size issue is to do with your graphics card. On my GeForce 2 MX I can have any image dimension I want until I use transparency then it wants power of 2 sized textures.

If you use an odd image size on a graphics card that supports it, then you can expect compatability problems with users who dont have such a card.
