Is there a way to have simmetry in two axis at the same time?

[Alejandro]

As the title says, I would like to use simmetry for both the X and Y axis at the same time.
I can only toggle one axis at a time, is there a way to achive this?

In Edit mode, use a mirror modifier and turn on the axis you want.

Not sure about in sculpt mode.

[Alejandro]

Sorry? Mirror modifier? I wasn't aware that Substance Painter 2 had those, where can I find them?

[Pte Jack]

DOH, My Bad, I should read the Group the question was asked in. Sorry, Only one at a time in SP2, that I know of. (I'm so use to answering in the Blender group... Again sorry for the mislead.)

[Alejandro]

No problem! Thanks for the reply anyway.

A workaround for this would be to have each identical quarter sharing the same uv map.
I just did a quick test for this and it worked(quartering a cube), I don't know if it's perfect but the basic principal is sound.

Do this by :

1) Getting rid of the mirror modifiers.
2) Unwrapping the remaining quarter of the model.
3) Duplicating this quarter 3 times and rotating each quarter into the correct place.
4) Removing(joining) the double verts that exist along the seams of the four quarters.

When imported into SP2 you can now paint on all four quarters simultaneously. You could even use this method for 3 axis symmetry where it will paint on each of the identical eighths at the same time.

Theory is sound there Chappy, biggest problem would be ensuring the verts line up in the UV and possibily there may be seaminng issues. It also limits detailing to individual 1/4's, They either all have or none of them have it (in the exact same place), type thing.

Hi Pte,

Duplicating the single unwrapped quarter ensures all the verts line up exactly, tried and tested this part.

Agree there could be seeming issues but then again I thought that could happen with the std symmetry approach? I sometimes have problems wherever there is a seam regardless of using symmetry, but maybe I'm messing something up myself when this happens, I'm no pro at SP2...

For final detailing you could simply change the Material ID on each quarter in whichever 3D software used(Blender etc). Then load in the same texture set(and duplicate material?) for each new ID in SP2 and then paint on the final details... I think...???

[Pte Jack]

I think that would be the only way of getting detail on the individual panels, by giving them individual materials after the initial painting. Depends on the game engine you're going to use in the end and how it handles materials. Have them as one mat for initial painting, split the quarters into separate mats and load the first mat as a fill layer, then paint on the detail...., save that panel and move on to the next...

[Alejandro]

Yeah...I think I'm just going to keep eyeballing this.

I often use alphas as a way to "sculpt" details into my models, and even though I may need the overall texture to be different it would have been nice to have a way to mirror these details on more than one axis at a time.

Hella old thread but a work around for this is.

1. Create a paint layer and paint your pattern with the one axis mirrored. say x axis for example.

2. Duplicate that layer

3. Right click duplicated layer add filter mirror the second axis you want say y axis for example.
Now depending on your uvs the pattern may be not where you want.

4. To fix that right click the same layer and add filter transform you can go into the filters settings and change the offset and rotation of the mirror.

The next problem to solve is the fact that your original pattern you wanted mirrored moved as well so you will end up with a duplicated patter on the initial side of your model.

5. To fix that simple right click the duplicated layer and add a white mask. Select the mask and paint over the the problem areas with a brush set to black.

Success.

A few downsides to this method you will probably not get 1-1 perfect symmetry but it can be very close much more so then hand painting.

Its probably possible to do with with a fill layer for a non destructive approach but it may end up being more complicated specifically in regards to step 5 because your already working in a mask so I suppose maybe you could add a paint to the mask above everything.

I used this method to create stitching on a football/handeggg

I hope this proves useful to anyone.
