Yep, it didn’t load from built-ins.

When I update my custom render script to the newest version (after [this commit](https://github.com/defold/defold/commit/5005a904c6a502a21dfaff17eff65987c1cb5964)) I’m getting the below error when building:

```lua
ERROR:SCRIPT: render/custom.render_script:80: bad argument #1 to '__mul' (matrix4 expected, got nil)
stack traceback:
  [C]:-1: in function __mul
  render/custom.render_script:80: in function update_camera
  render/custom.render_script:104: in function update_state
  render/custom.render_script:316: in function <render/custom.render_script:310>

```

As the camera projection is nil, it throws a multiplication error. I don’t know why the projection was nil, but I have just added a second check - of the projection function return value, as below:

```lua
local function update_camera(camera, state)
    if camera.projection_fn and camera.projection_fn(camera, state) then
        camera.proj = camera.projection_fn(camera, state)
        camera.options.frustum = camera.proj * camera.view
    end
end

```

And it works fine.

Maybe it’s something to take a look at. Or maybe it’s just me, I don’t know for sure 😉

Hm that seems like a bug to me, could you share a repro or something that I can look at?

Here’s the repro:  
[mul-repro.zip](https://forum.defold.com/uploads/short-url/fpyUMhLZClXaqDzLjd4cQFb8qHd.zip) (496.6 KB)

It looks like the problem arises after adding `msg.post("@render:", "use_camera_projection")` to the camera object init function. So, I don’t know if it still classifies as a bug, because this is not the way to do it currently.
