Disabling Z buffer for a single scene

Game Engine Game Engine Support and Discussion

Hi,
I was wondering if it possible to disable the Z buffer for a single scene in the BGE.
Typically, I have my main scene and an overlay scene with around 100 objects.
For this second scene, I do not need a Z buffer, but rather a Z sorting done on object center or even no Z sorting at all.

I think this would probably save some memory and maybe speed up the rendering.

I used to have up to 4 simultaneous scenes but after thinking about it, I though this was stupid because of this additional memory consumption (or CPU consumption if the same Z buffer is used for all the scenes but with a clearing between each ).

Any comments on this subject?

I do not think you can disable z-Buffer processing.

If you think you get performance or memory issues, you should look at your design if there is a way to reduce the amount of simultaneous scenes.
