What Type of Bug are you experiencing?

Stability

Steps to Reproduce

  1. Place any mesh in the scene. (Does not matter the mesh size or shape)
  2. Set the mesh to not be spatially loated, and to have infinite bounds (so it never stops rendering when far away)
  3. Set the scale to 65534.998, it will work.
  4. Set the scale to any value bigger, it will become invisible.

Expected Result

  • The objects should still be visible regardless of the scaling applied (even with absurdly bigger values such as 100000000.0, like it always worked before)

Observed Result

  • The object stops rendering on both the editor and client. Besides this, it still simulates (has collision, handle overlap events, and runs logic)

Platform(s)

Tested on:

  • Windows 11 (Intel + NVIDIA) - Editor and Client
  • Android 17 (Galaxy S25 Ultra) - Game Client

Additional Notes

You can see on the images attached above, where the white cube scaled upon a little before 65535 works, but after scalling to it or bigger than it, it stops rendering.

I think that this issue may have something to do with being at the boundary values of 2^16 (65536), where it is considered a 16 bit value in programming (usually on unsigned short integer). Also appearing on some places as 64KiB (65,536 - Wikipedia)
