1. Not all elements import into Twinmotion. Some pieces of walls, moldings, especially custom profiles do not transfer through. For some reason the edge of one of the plies of a roof composite does not show. Any idea why some components don't transfer through?
2. Is there a way to change the settings so that Twinmotion does not arrange elements by materials? For instance, all pine materials from ArchiCAD come through as one layer, and if I want to change the material in Twinmotion of one chair that has that pine material assigned to it, it changes that material throughout the imported project. I'l like to be able to split them up. Is this possible?
Other than those issues, I find Twinmotion relatively easy to work with and you can come out with great renderings and movies fairly quickly.
Please send me a PM with the link and I'll send you files.
Thank you for the screenshot, this helps a lot!
For the first issue, it doesn't look like there are missing elements, but rather they were not exported properly. My suggestion is to untick the option "Optimize the geometry. This tends to cause problems with the element's geometry when transferring to Twinmotion, therefore we advise to turn it off for a correct export.
For the second issue, it is true that if you select No Merge, elements will be exported to separate layers. I'm not sure if we can delete them, but there might be a way to replace the materials for selected layers.
Let me know if the above suggestion helps you with solving the issue, then we'll see from here if this is what causes the issue. Thank you very much!
