i make tank track effect but not exist another way?

i make it that similar to animation

(youtube video tag did not act;;;; )


it is have texture 128 files, so that it is able to animate

but i forget change alpha channel (material transparency)
ntice it, howeve,i don’t know how to movealhpa channel (it is) not able to copy)

so i realize

if it able to Lua?!

In fact
i try to do it in lua but i did’t find how to do
so i make animation…

lua be not able to move(shift) material(material position)?

You could use LinearRamp .vmt/material proxy to move the texture itself instead of making an animation.
