Help! GL error since 3.2.0-alpha8

[BlackMojito]

Hi Folks,

I am getting below GL error when calling scene.pick() since 3.2.0-alpha8. I am not able to reproduce it with a simple background.  Would any one of you know what (which commit) might cause this? Everything worked correctly with alpha7.

[.Offscreen-For-WebGL-0C016078]GL ERROR :GL_INVALID_OPERATION : glDrawElements: uniform buffers : buffer or buffer range not large enough at index 0.

 

And the result is that my CustomRenderTargets in the Scene cannot be rendered any more...

Hi,

would you be able to reproduce this on the playground? so we can see exactly what went wrong?

[BlackMojito]

I tried but I could not reproduce it in a simple playground. But in my code, I am pretty sure that it is when executing scene.pick() that the GL error occurs. 

Would you please give me some debugging instructions so that I can narrow a little bit the cause? In the meantime I will try to see how I can reproduce it...

Thanks.

This can happen due to many reasons, but I doubt scene.pick is one of them. it might be a callback executed after the scene pick has returned. Try removing callbacks registered and see which one is causing this. The try reproducing this specific function on the playground so we can understand what was changed and if it is a bug.

also, you can share your page online with a reference to babylon.max.js so we can debug it live

Sorry it hasn't been deployed yet. Everything is executed at localhost at the moment.

BTW, when using Webpack, how can I link babylon.max.js instead of babylon.js?

Have you tried this:

1. add babylon.max.js as a script to your  HTML:
<script src="https://preview.babylonjs.com/babylon.max.js"></script>

2. add to webpack config:
new webpack.ProvidePlugin({ BABYLON: 'babylonjs', }),
I didn't actually try that, but should work.

edit. or via externals:
