EDIT: Ok i managed to achieve the old look by doing this:
Solidify Modifier with thickness: 0.001
Setting the Specular value from pricipaled Bsdf to 0.025 (Does not look good in Blender, but in Verge)
these are Things, that worked out of the box with 2.80.
So far so good. If use the value nodes in blender they work correctly as expected
and move the texture along x axis and y axis, just how i want it.
Now in Puzzle Editor i use the change value puzzle , but nomatter what value i enter , the texture is jumping always to the same place, no matter how big/small , positive / negative the value is.
I attached my nodesetup – maybe im missing something, but as i said in Blender it works as you would expect it.
thanks
