…ets`, Add render function in RenderPass and make properties optional.

Can you provide an example or show in the code where scene or camera can be optional/undefined?

One common way is to pass undefined in the constructor and assign the camera, scene before rendering. This way passes can be initialized before the scene/camera init/load.
But if its confusing I can remove this change.

I'm just concerned about the properties becoming optional since that would cause any access of those properties to assert that they're not undefined or check for it. I would feel better if there were some official three.js examples that show this pattern.

Shouldn't the parameters be readBuffer and writeBuffer (in that order)?

In three.js RenderPass.js, the first parameter is ignored and the second parameter is used as writeBuffer.
The autocomplete always creates confusion since the params are not write, read but ignored, write

So the variables are misnamed in the three.js source code?

I think the better fix would be to have WebGLMultipleRenderTargets extend WebGLRenderTarget like it does in the three.js source code.

I tried but since the type of texture is an object in WebGLRenderTarget and an array in WebGLMultipleRenderTargets, its not possible to inherit and change type of the property in typescript. This seemed to be the simplest solution for Passes atleast.
One way is to make texture to be Texture|Texture[] in WebGLRenderTarget but that might break a lot of projects and require special type casting at many places.
Another way is to make an interface like IWebGLRenderTarget and make both implement it.
I am open to other ideas, would be good to fix type handling of WebGLMultipleRenderTargets.

Changes in Pass and RenderPass
What
Allow
WebGLMultipleRenderTargetsinPass.renderfor read and write buffers. This is required becauseWebGLMultipleRenderTargetsdoes not inherit from WebGLRenderTarget in this types repo(but it does in three.js)Allow
readBuffer,deltaTime,maskActiveto be optional in Pass.Add render function in RenderPass, which is slightly different from Pass.
