I made a simple spritesheet of some clouds, thinking that it would be easy to have the STK engine play the animation to add some more depth to the sky in my tracks/experiments.
I was so wrong.
I won't go into detail about everything I tried, but no matter what, the clouds would always render like this:
After a while, I decided to try swapping one of the working animations' texture out for the cloud texture, hoping that it would at least give me something to work with. But as you can see in the image above, I got a grid pattern (probably the spritesheet tiled horizontally), instead of a nice cloud timelapse.
By this point, I'm at a complete loss for what to try. Normally, I'd create an issue on github, but it just doesn't make enough sense that a specific texture would mess up a feature in the game engine.
So I'm posting this, hoping that someone else will be able to get the animation to work or at least make sense of what's going on.
Here's the image, and thanks in advance:
