So I wondering if anyone knows a way to make all (0,0,0) colored pixels to transparent I\'v acomplished this by saving the image to a bmp file then loading it and pasting the image with transparency. But it is really freaking slow. there is another perameter in the
dbSetCameraToImage() function with iGenAlpha could this perhaps be the answer?

I think a really cool effect can be accomplished.

[edit] Is there a way to set the camera's viewport where there are transparent portions ( so its not just a box )

[edit] NVRM that would defeat the purpose. cause Im trying to get that tracer effect that comes with turning off the backdrop .

Remember that you can make objects to appear only at certain cameras wih set object mask... Wouldn't that achieve what you want? Show only one object and the others shown as 'transparent' for that camera....

I don't know if that will be as cool as you describe, but yes you can do this (I guess you want it just for one object) with an additional camera and set object mask. Turn of the backdrop for the additional camera and play around.
Oh eventually you'll need a screen quad object to output the render of the additional camera, won't you?
Good luck

Want i was initially thinking that I wanted to put a hole in the center of the screen, but i soon decided it was probably impossible my next guess is the camera to image but, now the object mask thing seems to me a very reasonable effect to get out of all this.
