Voxel Texture Stretching

[Craft4D]

I am not really sure why but my terrain texture is stretching in a few places on my voxel cave and I am not sure why. I can fix it by remodeling the voxel but sometimes that causes me to loss the desired shapes I am looking for. Anyone know why there is so much stretching and if there is a better way to fix it?

are you using the 3d materials ? It would be better if you could post some screen-shots of the issue.
