How to show something behind an occlusion shader?
Example scene:
- After mapping out a room, we detect that there is a Wall divider, and the enemy is setup to hide behind it.
I have the occlusion renderer on the wall surface, which successfully hides the enemy.
However, the enemy has a beacon on them. That beacon I want the player to be able to see. I.e. it should show up through the occlusion shader wall.
Is that possible? How do I modify the shader of the beacon object or of the wall to see it?

If you add "ZTest Always" to your beacon shader it will always pass the depth test (z comparison) and it will always be drawn.

I think the easiest path would be to draw a raycast from the camera to the beacon and determine where the wall intercepts your line. Then place a copy of the beacon just in front of your occlusion.

ZTest did it.
Thanks!
