Expo GL does not support the new ArchitechtureΒ #7

@IAlphaOmegaI

Description

@IAlphaOmegaI

Issue: Black Screen, no environments, no lights and no meshes load at all, no explicit error or warnings, but nothing actually loads.

Run on a real IOS device through a dev build;
Tried on both expo@51 with the following app config:

  plugins: [
    "expo-router",
    [
      "expo-build-properties",
      {
        ios: {
          newArchEnabled: true,
        },
        android: {
          newArchEnabled: true,
        },
      },
    ],
  ],

and on the expo@52 with the

newArchEnabled: true

flag on the root of the config;

Here is the code:

import { Canvas, useFrame } from "@react-three/fiber";
import { Environment, useGLTF } from "@react-three/drei/native";
import { Suspense } from "react";
import { Bloom, EffectComposer } from "@react-three/postprocessing";

export default () => {
  return (
    <Canvas camera={{ position: [-6, 0, 16], fov: 36 }}>
      <color attach="background" args={[0xe2f4df]} />
      <ambientLight />
      <directionalLight intensity={1.1} position={[0.5, 0, 0.866]} />
      <directionalLight intensity={0.8} position={[-6, 2, 2]} />

      <Suspense>
        <Environment preset="park" />
        <IPhone />
      </Suspense>

      <EffectComposer>
        <Bloom intensity={1.5} luminanceThreshold={0.9} />
      </EffectComposer>
    </Canvas>
  );
};

const IPhone = () => {
  const asset: string = require("../../../assets/models/iphone.glb");
  const { scene } = useGLTF(asset);
  useFrame(() => {
    scene.rotation.y += 0.01;
  });
  return <primitive object={scene} />;
};

This app is part of a turborepo monorepo:

metro.config.js

// Learn more https://docs.expo.io/guides/customizing-metro
const { getDefaultConfig } = require("expo/metro-config");
const path = require("node:path");
const {
  withTurborepoManagedCache,
  withWorkspace,
  withSVGTransformer,
  withNativeWind,
with3DAssets
  composePlugins,
} = require("@zenncore/config/native");

const PROJECT_ROOT = __dirname;
const WORKSPACE_ROOT = path.resolve(PROJECT_ROOT, "../..");

const withZenncore = composePlugins(
  (config) => withSVGTransformer(config, WORKSPACE_ROOT),
  (config) => withNativeWind(config, WORKSPACE_ROOT),
  (config) => withWorkspace(config, WORKSPACE_ROOT, PROJECT_ROOT),
  (config) => withTurborepoManagedCache(config, PROJECT_ROOT),
  (config) => with3DAssets(config)
);

/** @type {import('expo/metro-config').MetroConfig} */
const config = getDefaultConfig(PROJECT_ROOT);

module.exports = withZenncore(config);

Otherwise works great on the old architecture!
