Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]
With the addon settings shown in the screenshot, building double or triple ties does not happen.
Hi, thanks for the report. Please share file you're importing
This happens to me on any .pdb file
cc @Blendphys
I don't understand what "cc" means
Hi @Shymanovich-Siarhei and @PratikPB2123 ,
thanks for the report.
So, with version 3.5.0 it works, I have to rebuild Blender to see what happens with 3.5.1 etc. This needs some time ... . Meanwhile, can you tell us if the PDB file from above contains also tripple bonds? Thx in advance.
@Shymanovich-Siarhei , this doesn't answer my question: do you expect a tripple bond from your PDB file?
BTW: I see a double bond in the first image.
Considering the CONECT data in your PDB file, I only find one double bond. It is basically Atom 3 that connects two times to atom 8, and vice versa.
CONECT 1 7 9
CONECT 2 8 20
CONECT 3 8 8
CONECT 4 6 15 16
CONECT 5 6 7 10 11
CONECT 6 4 5 8 12
CONECT 7 1 5 13 14
CONECT 8 2 3 3 6
CONECT 9 1 17 18 19
CONECT 10 5
CONECT 11 5
CONECT 12 6
CONECT 13 7
CONECT 14 7
CONECT 15 4
CONECT 16 4
CONECT 17 9
CONECT 18 9
CONECT 19 9
CONECT 20 2
there is only one double bond in this file. the problem is exactly the same with the triple bond. i just don't have the triple bond file handy right now
@Shymanovich-Siarhei , you have sent exactly the same message as before, without giving an answer ... . Anyway, I think that the importer works: you have one double bond that is also shown in Blender.
Connections are only displayed in "normal" mode. no connections in "dupliverts" mode!
Yes, but this is needed. Please, send us the PDB file with the tripple bond ... thx in advance.
You mean, vice-versa? ... well, I'm compiling Blender right now, I will see later on ... .
there are both double and triple bonds in this file
@Shymanovich-Siarhei
Okay, but the triple bonds are correctly shown with the Dupliverts switched on. So, why do you want them in the normal mode? Any reason to avoid dupliverts?
I noticed a bug in the plugin! the checkbox "display double and triple bonds" in "normal" mode is there, but it does not work. "Dupliverts" mode does not work well if the material of the constructed molecule is glass - in this case segments are visible. if you render in evee the same way - segments are visible!
@Shymanovich-Siarhei
Now I understand! ;-) Okay, I have Blender 4.0.0 Alpha now, I will see what I can do ... . Be patient plz. ;-)
Dear @Shymanovich-Siarhei .
The
normalrepresentation mode does now show double and tripple bonds! This will be delivered from Blender version 3.6 onward. Those 'issues' you can see in the sticks, when using glass-like material and the dupliverts representation mode, are special. I will see how I can improve this. BTW, you can now also place double and tripple bonds closer together. Before, the distance was restricted.You now have to use version 3.6 or later. Either, you compile Blender yourself (you get the code from the git Blender repro, read here) or you just download the version from here. Note that you can also use version 4.0 alpha.
Cheers.
PS 1: Let me know if things work ...
PS 2 (EDIT): BTW, you can discuss things better here
downloaded the new version of blender... don't see any changes
Hi, wait until tomorrow for builds on website to update: https://builder.blender.org/download/daily/
@Shymanovich-Siarhei ,
you have to wait probably this night because those are the daily builds ... . Best is, if you compile the newest Blender ... .
Evil hack: you can download all from here and replace the old files in the correct directory where the add-on is inside on your system. ;-)
all good, everything works! thanks! checked double and triple links, checked the distance. blender versions 3.2.2, 4.0.0
