The latest version of Hexagon does have various issues. I would first suggest some steps to try to find where the problem lies.
1. If Hexagon has crashed, there is the possibility that the configuration file as become corrupted. So first, open Hexagon and “File-> User Resources-> Reset all”. Then restart Hexagon. (sometimes, even resetting Hexagon will not be enough, as the configuration file itself may required manually deleting. Hexagon does create a new config file on re-start).
2. There can be problems due to the OpenGL optimization. The setting for that is in “Edit-> Preference editor” -> “3D display-> Advanced-> OpenGL optimization”. Change the setting to “No optimization”
3. The next problem can come from attempting to export objects while there is dynamic geometry active (although that was supposed to be fixed. I have seen reports stating it can still cause issues)
So for example, after you create your tubing, before you export to .obj file, select the object then go to the lower right hand side window “Dynamic Geometry” and click on the little lightening bolt, which will collapse the DG.
If you do not use the dynamic geometry, you may be best, in the dynamic geometry window drop down settings, set it to “No DG”, so you do not forget to collapse the DG.
Thank you so much for the tips. The first two actions saved my day, HEX is now stable again. I don’t know exactly what was wrong with my settings, or what had been corrupted, as it used to work fine formerly. Anyway I have printed and saved your steps so I can easily find and follow them again, if necessary.
HEX used to crash on me even after extremely simple activities like creating a primitive cube, not doing much with it (some translation or resizing) and moving the camera perspective… bang#?@&&*§... Sometimes I had a feeling it happened more often when doing some tesselation, but then again, short after starting HEX and just creating a first primitive cube,,, bang#?@&&*§... So I guess in my case this smells like a corrupt configuration file, like you described in step one. There had also been some anomalies with some icons after starting the program, the UI wasn’t built up properly, and just hovering over the incorrect icons transfered them into what they were supposed to be, another indication that is was the configuration file, right? But I didn’t have the patience to try the steps one by one, instead I did 1, then restart HEX, then step 2, restart HEX again, and wooooow, after 3 hours it still seems stable.
This was needed desperately, I have a project running, and couldn’t afford the time to introduce myself in modeling in my Carrara Pro 8.5 or Blender or Wings3D… Like DidrikB said in a comment above, I simply love the interface of HEXAGON and I want THIS. I don’t want it for FREE, I am very ready to pay for a fair price and would immediately purchase a new version, IF IT IS STABLE. However, now it seems reliable enough again to continue my work without switching to other software, am a happy guy now.
