How to make camera ignore entity?

[naomijub]

So, I've been working on this PR, which has at least 3 cameras, play mode camera, editor camera and simulate playmode camera in another view tab. The issue is that I want to ignore debug_grid in the newly created camera, but not in the editor camera.

I remember that around version 0.8 I could do it with render pass, but I'm not sure how to do it now

Perhaps you can solve it with render layers:

bevy/examples/3d/render_to_texture.rs

Line 75 in 8067e46

let first_pass_layer = RenderLayers::layer(1);

If the debug grid is on layer n, you can opt-in to rendering this layer on a per-camera basis by adding layer n to those cameras as well afaik.

The example shows that the last camera pass uses the default layer 0, so it does not see the layer 1 stuff earlier in the example.

Is there a way to just opt out a layer? I feel that defining layers this way could become very rigid for other users

[torsteingrindvik]

Not sure I'm following what you mean?

If I understood your problem, you could:

1. Add the debug grid to render layer e.g. 1
2. Make editor camera render this layer
3. Don't add this layer to the new camera, it won't render the debug grid then since it's not on the default 0 layer

Hey, tried doing this but I seemed to have done something wrong, can you check the PR and help?
The commit hash is 239e474 and this is the image I have right now when adding a playmode camera and a mesh obj.

Hm I can't easily tell by just looking at the commit.

Gut feeling is that perhaps the combination of

• Render layers
• Not clearing cameras (I saw clear color none)
• Render ordering

might have hit a but somewhere.
