Error Message: Could not show visualisation, please try with different input

šŸš€ Support (Q&A)
1

Hi all,

Iā€™ve written the script below, however once in the online 3D visualiser, I get ā€œAn error occurred while generating the resultsā€ and ā€œCould not show visualisation, please try with different input.ā€

Iā€™ve tried a few different changes including the addition of params. in front of the parameters as well as changing **kwargs to ā€œGroupā€.

.translate doesnā€™t seem to work and at one point I had the error message: Attributeerror: Materialā€¦ā€˜translateā€™ (I cannot remember the middle part).

Any help and guidance is much appreciated!

Solved: .translate accidently added to incorrect objects. They were added to the material object as opposed to the SquareBeam objects.
