Just thinking out loud…I often wonder what folk mean when they make a broad statement like “unstable”. Does this refer to some inherently bad code that causes it to simply crash for no reason at all? Can’t be, because it works very well for others who have the same setup.
In my experience, Hex throws a fit if the operator does something when Hex is expecting something else - like giving it a task while it is waiting for one task to be completed and validated before moving on, or trying to use a curve to do something before completing the operation by collapsing DG.
Then there is simply bad mesh construction - not following basic rules. Over the years I’ve seen so much of this passed off as “advice” and think to myself that it’s no wonder the adviser says Hex is unstable, if this is their normal working method. Hex doesn’t have too much of a problem handling bad mesh, but when one tries to export as .obj, it can’t write the file and crashes.
Why I feel that a lot of the problems are caused by pilot error is that when I first started in Hex, I had frequent crashes - as i learned more about it, the crashes became less and less and now I can do really complex, heavy models without any problem.
A couple of things I’ve picked up in the forum that are worth trying out to improve “stability” - on Win7 64 bit, instead of installing Hex in the default X86 directory where 32 bit apps are supposed to go, install in the the normal Program Files and make it LAA. Set your graphics card to “Let application decide”. If you don’t have a really good graphics card, set OGL preferences to “No optimisation”.
Use the Universal Manipulator exclusively.
If in doubt whether validation is required, validate anyway - won’t do any harm. A good indicator that validation is required is if the UM doesn’t show after completing an operation.
As for alternates, Blender is really good and not really all that bad once you make the effort. Wings 3D is good, but I never really made an effort to understand it. Probably the easiest of all to learn and which gave me my grounding to move to Hex is Anim8or - free, simple, with some surprisingly advanced features.
Until Nvil (which is a seriously good app) came on the scene, I was convinced that there was no future for stand-alone modeling apps.
I doubt that Hex will see any further development while in the hands of Daz. It fulfills Daz’s need to have a modeling companion to Studio and is very capable of doing the very basic type of modeling required to do morphs and make clothing. Daz management is convinced that the modeling capabilities of Carrara are better than Hex’s and if there is to be any further modeling development, it will surely be either in Carrara or Studio will get some basic modeling features.
