Utilize the WebGLRenderTarget again

In my project, I am working with two scenes: the main scene which displays a textured plane, and a secondary scene that needs to be rendered to a texture. This texture will serve as a map for the main scene's plane.

Although most THREE.WebGLRenderTarget examples redraw both scenes each frame, I specifically need the secondary scene to only be rendered once. After rendering, I want the result to be stored as a standard texture.

If you'd like to see a simplified version of the project, check out this fiddle: here. In the animate() function, feel free to remove the condition if(i === 0) so that the second scene is rendered every frame.

Answer №1

Make sure to handle texture loading asynchronously before utilizing it.

To achieve this, you can trigger the animate() function within the loader callback.

beginTexture = new THREE.TextureLoader().load( "https://i.imgur.com/eoQwyRb.png", animate );

Alternatively, incorporating a loading manager could provide another effective solution.
