Member rooattack Posted March 21, 2016 Member Report Share Posted March 21, 2016 There is a bug affecting every model I create. It's really inconsistent. Sometimes when I undo or smooth, or turn symmetry off, it corrupts my mesh and is irreparable. It basically causes he mesh to have zero width on some part of it. I can't even undo to reverse the changes and hope to god that I have saved a recent backup. See attachment to view what happens. Notice the top part of the model's head that looks like its see through and pixelated almost. 1 Quote Link to comment Share on other sites More sharing options...
Contributor Michaelgdrs Posted March 21, 2016 Contributor Report Share Posted March 21, 2016 Is this voxels? Your version and OS? If you create a cube and start working it does the same? Can you post a video showing the problem? Quote Link to comment Share on other sites More sharing options...
Member rooattack Posted March 21, 2016 Author Member Report Share Posted March 21, 2016 Yes it happens with every model I have. It's random so I can't reproduce it always. I just had to completely redo a model a few mins ago because it corrupted multiple voxels. See attached. It always creates these jagged edges around the model. 1 Quote Link to comment Share on other sites More sharing options...
Advanced Member Gary Dave Posted March 21, 2016 Advanced Member Report Share Posted March 21, 2016 That is super weird. One thing that might help shine some light on this, is if you could get something like Bandicam and record yourself as you work, then, when it happens again, just upload the video to youtube and we can take a look at what might be causing it. Aside from that though, can you give us a rough break-down of your usual procedure? ie:- import mesh from other app into voxel room / create primitive in voxel room - mostly use tools X,Y,Z - etc 1 Quote Link to comment Share on other sites More sharing options...
Carlosan Posted March 21, 2016 Report Share Posted March 21, 2016 Could try to use another version as CUDA or DX or openGL ? 1 Quote Link to comment Share on other sites More sharing options...
Member rooattack Posted March 22, 2016 Author Member Report Share Posted March 22, 2016 Ive attached one of the models that it has affected. Not sure if it can be diagnosed this way. If I reinstall 3D coat, will I lose all of my workspace and presets? issue.3b.zip 1 Quote Link to comment Share on other sites More sharing options...
Reputable Contributor AbnRanger Posted March 22, 2016 Reputable Contributor Report Share Posted March 22, 2016 Ive attached one of the models that it has affected. Not sure if it can be diagnosed this way. If I reinstall 3D coat, will I lose all of my workspace and presets? It's a necessary practice to save your UI Workspace/Layouts (WINDOWS menu), Hotkey layouts (EDIT menu), if you added your own custom hotkeys, Presets (via drop0list toggle in upper right portion of the panel), and any Custom Navigation settings. Also, if you created a Custom Theme, you will want to save that as well. Once done, whenever you have really strange, bug-like behavior, try the simplest thing first...restart the app. Sometimes that is all it takes. If that doesn't help, one or more of the .XML files in your "MyDocs/3D Coat 4.5" directory may have gotten fudged up. I will delete all of those .xml files (careful not to delete the LICENSE.DAT or any of the sub folders) > Re-install. That fixes the problem many times. There was an UNDO bug that was recently reported and supposedly fixed in the latest build (4.5.32), so I would try the steps I mentioned > install the latest build > reload your layout and presets. It may seem like a lot, but in practice, it only takes a couple of minutes at most.. 2 Quote Link to comment Share on other sites More sharing options...
Contributor Michaelgdrs Posted March 22, 2016 Contributor Report Share Posted March 22, 2016 You have a couple maybe more solutions to try now , please let us know for the outcome. Quote Link to comment Share on other sites More sharing options...
Member rooattack Posted April 8, 2016 Author Member Report Share Posted April 8, 2016 I did exactly as mentioned with reinstalling. The issue is intermittent, so I will have to create some models and come back to respond. Thank you so much for that advice! Quote Link to comment Share on other sites More sharing options...
Member kait kybar Posted April 8, 2016 Member Report Share Posted April 8, 2016 Hi. Its happening quite often but what helps Is to convert mesh to global (assign shortcut) So after every major tweak, make it global. Maybe its not a right solution though.

Member rooattack Posted April 11, 2016 Author Member Report Share Posted April 11, 2016 Hi. Its happening quite often but what helps Is to convert mesh to global (assign shortcut) So after every major tweak, make it global. Maybe its not a right solution though. When I do that, it changes the position of the object sometimes. I just found out that this is consistently occurring when I 'subtract' elements from other elements. So if I use an 'import' object and hold 'ctrl' to subtract that shape from another shape, it happens. Or when I use a Primitive to subtract from another object. I wonder if it could be some kind of graphics card thing. Attached an image of my Apple hardware build Quote Link to comment Share on other sites More sharing options...
Member rooattack Posted April 11, 2016 Author Member Report Share Posted April 11, 2016 I just captured a video of it! See attached. I wasn't even on the layer that it corrupted. I was importing an object on a separate layer then clicking on another tool to exit the import mode. 3d coat bug.mov Quote Link to comment Share on other sites More sharing options...

Contributor ajz3d Posted April 11, 2016 Contributor Report Share Posted April 11, 2016 Shooting in the dark here, but have you perhaps tried importing your models without voxelization? If you're importing to voxels you need to be sure that everything is watertight. The mesh needs to have some thickness, or you may run into some problems when 3D-Coat takes the process of making it thick into its own hands. I made it my habit to import everything without voxelization. This gives me 100% assurance that my mesh will import WYSIWYG. And only after my objects are imported, I convert them to voxels if it is necessary. This gives me total control over what happens with my mesh. Can you provide source geometry files which, when imported, will randomly generate this bug? Quote Link to comment Share on other sites More sharing options...

Do what AJZ said...just switch the layer to Surface mode before you hit the APPLY button or ENTER key, and it will commit the object to that layer as a surface mode (mesh only) object. Then, if you want to use voxels, first RMB + Click the layer > choose THICKEN. The default is probably way too thick. Try .5 first and work from there.
