tiling issue and LookAt constraine

Hi guys
I’ve encountered the following issues, may some one have advice:

1.
Turn off the tiling checkboxes in 3ds Max,
then animate the offset so that the texture wraps around the geometry and fades out
– it works in Max, but in Verge, the textures aren’t visible at all

2. I constantly run into problems with Lookat Constraint -I’ve already stopped using the “Keep Position” checkbox. I understand it didn’t work correctly before, but everything is fine in Max. However, when I export, some objects work fine while others fly off to the side or shift slightly.
Which settings should I avoid?
