Hi all,

Is there any way to force a camera view to draw? I have 4 cameras all showing different views of my world (they render to 4 seperates parts of the screen). What I want to do is set the game state - draw the view from the first camera, change the state - draw from the second camera and so on all before I swap buffers using sync. I am trying to avoid writing a dll as the whole rapid prototyping thing goes out the window.

Thanks in advance.

Darren.

Currently the sync does all those operations. I suggested to Lee that he provide seperate commands for rendering and flipping, and he said that SYNCRENDER and SYNCFLIP sounded like a good idea and may be added soon.

Do you want Windows menus in your DBP apps? - Get my plugin: http://snow.prohosting.com/~clone99/downloads/tpc_menus_103.zip

Here's a suggestion - it may take a little work on your part though.

Set up all 4 cameras to draw to images, then when you want to update the view of one, paste that image to your bitmap in the appropriate spot.

Not very efficient, as all 4 views will still be rendered to the images behind the scenes, but workable.

Thanks for the replies. I don't think rendering to a set of images would make any difference as I cannot force a camera to draw. If I understand the sync command correctly then the camera to texture draw will happen for each camera just before the buffers are swapped. I want to draw to the backbuffer at a time I dictate and from the camera I choose.

Those commands would really improve multiple camera handling, hope they appear soon!

Thanks again
