Summary

UEFN Each of its dimensions must be a power of two (for example, 256x256, 512x512, 1024x1024, and so on).
This is wrong. the square root of 512 is approximately 22.62 (16x16 =256) someone has added 256 +256 = 512
(32x32 = 1024). Just calculate and test on Microsoft Calculator → Scientific and use the Square Root button to test the numbers

Steps to Reproduce

(512). Just calculate and test on Microsoft Calculator → Scientific
2. Enter 512 and use the Square Root button to test the numbers approx 22.67

  1. Look at “as long as each dimension is a power of two. For example, 256x512, 512x1024”

512 is NOT of Power Of 2

Expected Result

remove 1024 x 512 as its not power of 2 this is 256+256=512 256 x 256 = 65,536 and is Power of 2

Observed Result

square root 512 is about 22.67

Platform(s)

Windows 11 any PC

Additional Notes

Examples of acceptable image sizes are: 256x256, 512x512, or 1024x2048.
Textures that don’t use the power of two will not be optimized, causing instability and poor island performance.

Yep, @Jimbohalo10 is 100% correct, seems like mathemagic, but simply using a calculator to check, one will see what numbers work.

From something I read here,

I assume the optimisation of textures is relying on not triggering too many large 24bit floating point numbers from being generated.
