Transparent fluid when using Meta quest passthrough

[josemendez]

To enable passthrough on any quest (1,2 and 3). you have to set the background to black in the camera, this is fine because the user does not see this. It can not be any other color then black as that would cause the user to see this color.

Hi,

This shouldn't affect the fluid color whatsoever, unless the camera doesn't render anything else on top of the background. Fluids will refract whatever the camera has rendered after opaque objects have been rendered. If the camera just renders a black background, this will be what is seen trough the fluid.

if you want to see the headset's camera output trough the fluid, that's outside the scope of Obi's built-in rendering system and something you must implement yourself by using a custom fluid shader that samples the passthrough camera texture instead of the frame buffer after opaque rendering.


kind regards,
