Would it be possible to render objects after post processing?

šŸŒµ Needle Engine
21 
private cam: Camera;
onEnable() {
  this.cam = this.gameObject.getComponent(Camera);
}
onAfterRender(){
  this.cam.renderNow();
}
22

Something like this- typed on a phone, canā€™t verify right now :slightly_smiling_face:

23

Might be the method is called something else?
Or Iā€™m importing the wron camera
(I might add that TypeScript is very new to me, so things move a bit slowā€¦ :sweat_smile: )

Camera from @needle-tools/engine, not the one from three

25

Tried both

Then Iā€™ll have to check later, sorry, on the go right now
You can check if intellisense gives you the right name

28

I scrolled through all definitions.
But thereā€™s no hurry, I can wait :slight_smile:

Thank you anyway! :slight_smile:

I think its this.context.renderNow(myCam)

30

Or just use the threejs renderer directly, you can access it with this.context.renderer

31

Hereā€™s a WIP for a custom ā€œCameraLayerā€

import { Behaviour, Camera } from "@needle-tools/engine";
import { PerspectiveCamera } from "three";

// Documentation ā†’ https://docs.needle.tools/scripting

export class CameraLayer extends Behaviour {
    
    private cam: Camera | null = null;

    onEnable() {
        // getting the Camera component from the same GameObject
        this.cam = this.gameObject.getComponent(Camera);
        if (!this.cam) {
            console.warn("CameraLayer requires a Camera component");
            this.enabled = false;
        }
    }

    onAfterRender(): void {
        if (!this.cam) return;
        // we remember the current background as we want to turn it off for the layer
        const currentBackground = this.scene.background;
        // we don't want automatic color clear anymore here
        this.context.renderer.autoClearColor = false;
        // if this is a Perspective Cam, update the aspect
        if (this.cam.cam instanceof PerspectiveCamera) {
            this.context.updateAspect(this.cam.cam);
        }
        // clear background, render, and restore the background
        this.scene.background = null;
        this.context.renderNow(this.cam.cam);
        this.scene.background = currentBackground;
    }
}

I can not for the life of me get the other camera to render :person_shrugging:

Iā€™ve copied your code and have to cameras in my scene. Both cameras, as of now, is set to render the whole scene but from differen angles. But I only see what ā€œMain Cameraā€ is rendering.
Is there perhaps some setup in the scene I am missing?

33

Updated the code, now it should work :slightly_smiling_face:

34

Make sure the component is on the ā€œlayeredā€ camera
Make sure your main camera is tagged ā€œMainCameraā€

35

Hereā€™s how it should look for two cameras, the second one just draws on top of everything.

36

So weird. The code makes every sense as well?

Hereā€™s a screen grab of the two cameras aswell (FX Camera is the layered one)
Is there something Iā€™m doing wrong?

37

looks ok. maybe put it on ā€œdefaultā€ layer for now for testing?

38

I made a texture the render target and put a Raw image on top of the screen to confirm that the camera is indeed working, but I canā€™t seem to get it to render to the screen.
This is very confusing, it should work :sweat_smile:

Is it possible to get a videocall or something? Another day perhaps?

If I can get this method to work Iā€™m pretty much set regarding the project Iā€™m working on

Can you make an empty scene with just two cameras (one MainCamera) and a cube, and the second cam having the script?
