Hi,
Just a simple question. When I make camera 1, the program automatically set the view to camera 1 even if I set the current camera to 0. I only want to use the camera 1 for some small ingame cutscenes.
Thats why I am making the camera 1 in main loop and as soon as it finishes its job I am deleting the camera. Working fine but only problem is, the poly count becomes double. But it become normal again when the camera 1 get deleted and set the current camera to 0(the main player).
Any advice how do I do it?

Thanks in advance
Regards

I think you'll have to use "sync mask".



...will draw only to camera 0...



...will draw to camera 0 and camera 1

Decimal:
1 = Mask required to render camera 0 only
2 = Mask required to render camera 1 only
4 = Mask required to render camera 2 only
8 = Mask required to render camera 3 only
16 = Mask required to render camera 4 only
17 = Mask required to render camera 1 and camera 4

That should help I think.

Here's a great link for understanding "sync mask":

I think I don't understand it. How do I use it? I have a variable and when it is 0 I want to set the current camera 0 and when it is 1 I want to set the camera 1. I don't want to render 2 camera at a time.
Thanks for your reply.

Regards

Maybe my code is not quite right then. Could you post some sample code of your problem?

It might help in debugging it.

My code is very simple. I am making the camera 1(when I create it, program automatically set the camera to 1, which is ok). Then I run a timer or variable for the cutscene and when it is greater then some value I delete the camera 1 and set the current camera to 0. Thats it.

Say, cutscene is the variable for running the cutscene. If it is 0 then player can move and if it is 1 than the above condition runs and player can't move.

Here is the function.


EDIT: Now I am thinking, why camera 1. When I can use the camera 0 in stead of camera 1.

Thanks in advance
Regards

Unless you need to have 2 different views at the same time, or are doing some shader trickery, there is really no need (IMO) to have more than the standard camera.

If you have a cut-scene, simply save the camera coordinates and angles, then reposition the camera appropriately. Then when you are done, used the saved values to put it back into its original position.
