Hello,
Can you read an error message in your browser console?
Make sure that the file is for the latest version of LDD.
Is this file publicly available so that we can troubleshoot?

Hello,

Thank you for your help.
No, there is no error message on my browser. I 've tried with another LDD file : it is working.
The file is not publicy available but i can send it to you if you want.
Maybe, the file is too "heavy" (the modele is around 2200 bricks) ?

Have a good day

The LDD importer can import such an amount of bricks.

You can send it by email to Scrubs. You can find the email address by clicking "Contact Us" in the footer. 😉

Thank you.
It is done.

It is fixed now. Issue was with LDD parts that are made of one mesh but designed as multiple in Mecabricks. e.g. Tassel

Ok. I'd never be able to find the solution
