Hello Jon Simpson
There’s a solution to that
I textured your butterfly wings and it flapped without the texture going on or off
Check the video of the butterfly flapping without the texture going on or off
Here is what I did
I simply deleted the old texture and created new one and also also delete other tags as well
Try deleting the texture and tags then create a new but if the problem continues then you have to try out different render engines aside the one you’re currently using which will surely worked out for you 100%
You you want to know the render I used then it was C4D standard render
Let me know if you have any other questions
THANKS
