works better and better but if i key (with I key) a value in a texture node the value goes yellow like keyed but no key appears :
i tried with the time input node but nothing do the work ;;; on rendering the texture doesn't move / modify while time goes forward

(but tools are looking fine if they'll run)

i'm trying fake under water caustics

thanks to coders , it's a huge work

I noticed this too and posted a bug report on it. Seems to be widespread with textures, I was making f-curves for the texture normal map mipmap filter values. Also interesting is that the value at frame #1 didn't start at the default! Because I didn't key frame #1, it was unspecified and instead of using default, it started with the last value entered = my last key!
