[SOLVED] Layer architecture for FPS weapon?

[kungfooman]

Hi, I’m trying to make use of the layer system for rendering a FPS weapon “on top of everything else”, so the weapon doesn’t clip when the FPS player is near walls.

So for testing, my goal is: make the sphere render on top of everything else

I messed somewhat with the PlayCanvas layer editor, but I only have confusing results. E.g. I made a layer same as World layer and placed it in the Sublayers after World. Then I put the sphere into that new layer.

The result is: in editor its just rendered normally, in Play/Debug mode the sphere isn’t rendererd at all.

I guess I just don’t understand the layer system at all atm, somebody knows how to render something on top of everything else?

Edit: The reason I couldn’t see it in Play/Debug mode was that I forgot to add my new layer to the camera aswell. But still I can’t figure out how to render a model over everything else.

Edit 2: Ok, I just figured this out. The “secret” is to use a 2nd camera and set “ignore depth”. And put that camera into “MyFirstLayer”. In Sublayers, drag “MyFirstLayer” to the very bottom. That makes it render the sphere over everything else

If anybody has a better idea for this, answer are of course still welcome

The layer system is to control the order that things are rendered. So I would have the weapon layer render after the world and disable z/depth testing on the materials for the weapon.

Hm, yes, I first had that, setting entity.model.material.depthTest = false, but some of my models looked completely wrecked after setting it.

Looks like this then:

Switching cull mode didn’t “fix” this aswell

So I guess I gonna stay with the 2nd camera approach
