Hello ,
This certainly looks strange. I would need to take a look at your Twinmotion file to better understand what might be going wrong. Would you be able to submit a bug report here and upload your file for the support team to review and figure out what's going wrong? When submitting your file, be sure to sue the Resource Collector in the Edit menu of Twinmotion to package your file and texture data.
Best,
Raghib
