As of about an hour ago, models rendered through ViewportFrames are taking a long time to render in, or they don’t render at all.
IF they do render in, when you remove them from the ViewportFrame, they continue to be rendered through the viewport frame for an unknown amount of time, before switching to the new model parented to it.
Here is a few GIF’s demonstrating the bug.
This is the layout of the UI:
Clicking the right arrow button destroys the current viewport model, and clones in new item’s model, the camera also gets re-positioned to look at it.
in this gif, you see nothing is rendering in the viewport
In this gif, you see the explorer destroying and creating the new item (my mouse going off screen is clicking the arrow button to cycle):
After leaving an item selected, eventually it renders into the viewport, to which when I begin cycling the shop, it never unrenders for a random amount of seconds.
As stated, this just began happening in both studio and live servers. However nothing changed in my code.
I tried preloading the model’s descendants when cloned, however this changes nothing.
Edit: I changed nothing and it is working as expected again in studio
Edit 2: It appears to be place specific? Even if I publish the same place file to two different Places, it only occurs in one (happens in Firework Simulator 🎆 - Roblox but not FWS Dev - Roblox)
