To be honest I prefer to just create entirely new cams.

This can be done rather quickly in the following general steps:

-You'll need an image editor that supports layers, I use Photoshop

-Grab two texture images from stock image sites like sxc.hu, put them on separate layers with the "background" layer going on top

-Put the grid on top of everything else, make it transparent and non-editable

-Save the file as a template psd image

-Grab or create your own individual visual elements to be used in the levels (eg grenade machine, hand stone, sign post) and save these elements in separate psd files

-Draw up a rough sketch of the level first, I use Gimp for this

-Use the template to create separate screens that are then saved to bitmap format (Once the grid is removed) to import into the game

--To create platforms and walls simply cut out the "background" layer where needed so that the foreground layer shows through

--When putting in visual elements just grab them from the psd files you created before

-Presto! You have a brand new cam to be imported into the game
