Hi, Thanks very much for getting back to me regarding the error.
I deleted the Twinmotion content from the 5.2 folder. Disabled the contents plugin. Restarted the PC and verified the 5.2 build tried again. Enabled the plugin again. Now the datasmith plugin works including the datasmith twinmotion export with textures. Thank you.
Sorry, I cant be certain what solved the error as I maybe importing it into an architecture scene instead of game scene now. I will report back if I see the crash again and I will add a bug report.
Many thanks
