demostenes Posted May 22, 2019 Posted May 22, 2019 (edited) Import of this fbx crashes Unigine 2.8.0.1 (and Unigine keeps crashing just after start, if it is not deleted). It was created by export from Unigine, imported in 3dsmax 2015 and exported again from 3dsmax as fbx without any modifications (default export settings). test.7z Edited May 22, 2019 by demostenes
morbid Posted May 23, 2019 Posted May 23, 2019 Hello Demostenes, I've successfully imported this file in a default 2.8.0.1 project. Please, check your import parameters. Will resetting them to default help? Thanks. UPD I've reproduced the crash with your model only if "Import Tangent Space" is set to enabled. Is this your case?

I dont know, I was importing with default parametres and because of crash I am not able to verify what was there. But in log was some error about tangents.
morbid Posted May 23, 2019 Posted May 23, 2019 You can send me *.meta file. All Import options are listed there How to submit a good bug report --- FTP server for test scenes and user uploads: ftp://files.unigine.com user: upload password: 6xYkd6vLYWjpW6SN
demostenes Posted May 23, 2019 Author Posted May 23, 2019 You were right, I had import tangent space on, because this mesh has manually tunned tangents. test.fbx.meta
morbid Posted May 24, 2019 Posted May 24, 2019 To be more precise, the crash was caused by two options combined: import tangent space and merge surfaces by materials. We'll investigate this issue, thanks. How to submit a good bug report --- FTP server for test scenes and user uploads: ftp://files.unigine.com user: upload password: 6xYkd6vLYWjpW6SN
morbid Posted July 30, 2019 Posted July 30, 2019 Hi demostenes, We fixed the crash. It was caused by attempt to merge two different surfaces, one had tangents, and another didn't. Similar to the case with vertex color. This operation wouldn't be valid until your number of vertices equals to the number of tangents. Thanks!

demostenes Posted July 31, 2019 Author Posted July 31, 2019 OK and how it will behave now? What happens in such case? Some error in log?
morbid Posted July 31, 2019 Posted July 31, 2019 We'll generate default tangents for such surfaces and will print a warning. How to submit a good bug report --- FTP server for test scenes and user uploads: ftp://files.unigine.com user: upload password: 6xYkd6vLYWjpW6SN
