[Fixed] symmetry and Splines/Text

[TanKh]

As I am currently working on a project where I have to texture lots of character props that have unique UVs though they are symmetrical I struggle with 3DCoat's symmetry feature.
The Spline-Paint-Tool is very handy for painting clean strokes and supports the style I use on the chars.
Unfortunately there seems to be a bug in conjunction with the symmetry function of 3DCoat that stresses my workflow a lot.

Repro steps:

 

create two boxes in voxel room, each with same distance from center axis:

 

Drop those to Paint Room with AUTOPO:

 

Enable Symmetry and start using Spline-Paint:

 

 

Result on "source side":

Result on opposite side:

It looks like there is some strange twisting of the brush when painting the stroke.
This is even more visible when using the text-Tool:

Result on "source side":

Result on opposite side:

I would like to know if there any tips to make this work from my side or if there any plans to adress this issue. If you need further info I am eager to help.

best regards

t.

Hi

Bug confirmed and reported. Thx for point it up.

I tried, but my text is absolutely symmetric on both sides. I am trying to understand what is different from your attempts. What I do:

1) 2 symm cubes

2) Autopo, bake to paint

3) Hide sculpt objects

4) Add 3 points with text

5) Enter

Everything is perfect...

Hi Andrew,

I made some Screencaps in order to show the problem:

I made a couple more vids in order to reproduce with different results, my findings are:

- error amount seems to depend on the viewing angle when applying the type curve

- after a couple of tries the complete type-curve tool went nuts producing only ****** when applying. So I restarted 3DCoat after this and after every following try. The two examples above were done after a fresh restart of the program

- I had few tries where I could not see any error

Compared to my real-World problems the videos above show somewhat mild results. Here is the problem on my current character model:

https://1drv.ms/v/s!Aq7jih4QElkLtOUlENF_ldTDztg1bA?e=i4YHRc

the scale of my model is quite small so it may depend on that. The UVs are perfectly symmetrical, I wrote a Photoshop script to compensate the error by mirroring the right part of the texture to the left.

thanks,

t.

 

Edit: for me personally the text-tool problem is far less important than the one with the spline-tool. But those seem to have the same reasons....

Please send me the scene with text/curve. I am still unable to reproduce. Maybe fixed in my build ;)

Still works as expected... Try build 51 please.

Sorry for the delay, I was on vacation.

I installed build 54 without luck.

The problem is even worse than on the test file with my orignal work files. See attached video:

 

I attached the 3b file as well to this post.

Testings your project using latest version 4.9.54 i cant replicate this issue, sorry. Try resenting settings, it will help.

indeed, Resetting my prefs did work. Thanks a lot! 

Just one note:

The option to switch tablet settings to TabletPC seems to be missing in the preferences/general tab. I had to edit the prefs in order to get my tablet working again...

Glad you found it resolved.

Tablet settings are here -on latest version- please take a look
