Straightforward change and a reasonable feature. Not keen on the example explosion, but it's helpful for testing and learning.

i usually make an example after seeing it crop up in the help channel a couple times, then having something to just link to them is nice

maybe not include as a wasm example would be nice though

this one specifically could also just be merged into the already existing repeating_texture example, with a toggle to change between 2d and 3d

This is my longterm preference, but because of the way the screenshot tool is currently setup I like having it split out as a test for now. (cc @mockersf)

one thing that i did not test was seeing if wasm would complain about alignment, does ci test that?

[hukasu]

one thing that i could add is Text2ds on top of each rectangle with a small description like Repeat On Control Repeat Off

I like that :)

[hukasu]

should i also move the example to the asset folder (within examples) or on 2d is fine? name of the file is also ok?

[hukasu]

is the font size ok?
