- engine version:4.14.3
- SO: windows 7 Professional 64bits SP1
- when it happens: clicking in the 3rd material’s combobox in the mesh editor
- expected: open the combobox and give avaliable options.
- what actually happens: open the selected material in the material editor (the combobox isn’t opened)
- frequency: 1/10 times
- how to avoid: clicking and holding the mouse button
- how i replicated: in the “content example” project, i opened this mesh you can see in the ss attached and added a material (it only happens with at least 3 materials), first it was happening in a personal project (and with a higher frequency) then i tried to replicate in this project because it’s public and everyone can try to replicate it.
- my theory: i think what is actually happening is a double click, the “edit” option (from combobox) is exactly in the same place of the combobox so a double click would actually open the combobox and select the “edit” option, and it would open the material in the editor as expected, i’ve also noted that if i scroll the details panel the bug don’t happen anymore, and the edit option isn’t in the sameplace as the combobox anymore, what makes my theory stronger. After all of this the next step was check my mouse, since it could be a potential problem, i’ve tested my mouse for a long time and there was no double clicks, so i think the problem still may be in unreal.
Hey veccher,
So I have attempted to reproduce the issue you have outlined on my end, but with no luck. Since this repro is so minimal and I have not been able to replicate it, we more than likely won’t be able to file a bug report. If the occurrence was more consistent, and it ended up crashing or even breaking your mesh, then that would be grounds for a deeper investigation. Since you have a workaround, and the frequency is so low, we are going to mark this as resolved until a more concrete case can be established.
There was a known issue dealing with similar functionality within UMG where if you went to add an image and select a material from the dropdown, it would open the edit option as if the single dropdown click were counted as a double-click. This could be related, but it is hard to say for certain. In any case, I am going to mark this issue as resolved for now, but if you discover new information feel free to leave a comment which will reopen the issue.
Thanks,
