Me too

Chrome
The workshop loads, the models is load BUT models are invisibles.
Also If I adding new bricks they are invisible too.
All Bricks docking are visible but there isn't the up arrow to open it.

Firefox
after Cleared Cache= not at all, black screen, workshop don't works at all.

An "old version" of workshop is impossible to take online?
Just until bug of the new version is fixed

TNX scrubs!

For me, WebGL just shut off entirely

Mine doesn't show anything, it says no bricks are there, & the bricks don't even load up. It was working fine yesterday morning for me.

Clear your browser cache to have the latest version of the workshop. The whole platform has been updated yesterday.

If you did, please post the content of your browser console (F12 on chrome)

Sorry...
Cache re-cleared now.

Chrome & Firefox
The workshop loads, the models is load BUT models are invisibles.

I cleared my Cache but it still goes to black..

The model from Library is loaded BUT invisible on browers.

Also if it's all black I do: File>export>Obj+Mtl

and in photoshop 3D the model is loaded, visible, texture perfect, editable...

So I think the problem is in the browser model player/viewer

@brickeducation This is not an issue from Mecabricks but the 3D framework that I use. It looks like that there are issues with specific graphic cards. It may be solved in the future but as of today it is not something I can really have control over.

For people having an issue with WebGL I would need your operation system and version as well as your hardware (CPU and GPU). We are trying to gather as much information as possible to fix it.

A proper report shall look like this:
OS: macOS 10.12.6
CPU: 3.5Ghz Intel Core i7
GPU: Intel Iris Plus Graphics 650 15336MB

Is there a reason that you are using r113 already of threejs, Scrubs? r112 is the latest stable version.

@brickeducation I also need the most import element which is the graphic card type and your operating system.
@Sim yes there are some reasons. One of them is that there is some of my code that I committed recently on the threejs repository which is currently only on the dev version. I follow threejs very closely and try to help has much as I can with the project.

Reverting to stable is no option then. 😃
I see the related issue that you've created on the repository. Perhaps you can try to set up a test version with PR #18419 applied since you think that it is related and let them try if the fix would work.

I'm also seeing the "pow(f, e) will not work for negative f, use abs(f) or conditionally handle negative values if you expect them" warnings and downloadable font errors, but have no problems with Mecabricks after that. So these are not causing it.

R112 has the same issue anyway.
There has been a few things going on on twitter and threejs guys have asked to gather a list of impacted hardware.
I will just leave it a bit of time before looking more into it.

For me, the workshop isn't displaying at all. I know my laptop isn't as new as anyone else's but like the others, I didn't have a problem until after the update.
OS: Windows 7 Ultimate version 6.1 (build 7601: Service Pack 1)
CPU: Intel Core 2 Duo CPU T5670 @ 1.80GHz 1.80GHz
GPU: NVIDIA GeForce 8400M GS 256MB

If It doesn't display at all (full black page), it is likely something different. Make sure that you cleared the cache of your browser. If you did please provide the browser error log (F12 in chrome)

I am going to respond to your post on social media:

On my Huliet Packard, my Graphics card is an "Intel(R) HD Graphics Family", and my OS is "Windows 10"

Hope this helps.

Also, I am having a similar error to where the whole screen is black, but I also have the problem to where I cannot see the world grid or any models I am building.
