[Solved] Stencil Preview glitchy

[GimbalLock]

Hi forum,

I'm having trouble with stencil previews. If I choose camera mapping, the projection guide is way off to one corner, not centered to camera pov. Clicking Reset still keeps the preview inside the same square area. Using the green widget or the controls at the top of the screen moves the stencil around, but still inside the off-centered square. There's essentially no way to get the preview into the center of the screen.

I don't know if its related but I'm having other glitches with smart material preview just previewing as solid colors only (or normal map only) on some surfaces of a model while other surfaces on the same model will preview them correctly.

I have recent nVidia drivers and this happens in both DX and GL versions.

Click RMB over move icon , to reset preview

the projection guide is centered to stencil and to display center. not to smart material preview.

- Are you using latest version 4.8.15C ?

Hi Carlosan, thank you for your reply. It does reset the preview pattern, but only inside the square in the top left corner. It never centers the preview area itself.

I know it may have been distracting that the Smart Material Preview is open in my screenshot. I was not expecting it to fit inside automatically. It was just open when I captured the screen.

The problem is that the stencil preview does not center to my view in any way and never overlaps the model, so its practically useless in this state.

Yes, I use latest version.

I do not experience your same problem. Works as excecpted in beta version opengl 4.8.15C

In the picture.

1. What Carlosan said about recentering the image.

2. Turn tiling on or off... The viewport will fill with the entire stencil if turned on. 

3. Right click on the centered dot and it will expose the parameters you see in the picture.

4. Reset. This will center the stencil plus reset the stencil to full resolution.

Hi Digman,

As I mention all the tools for manipulating position of the stencil preview only moves it inside the square I pointed out in the screenshot. The square is fixed no matter what. Or was, as I could get it to work properly by switching to retopo room and back to paint - then it would jump to fill out the screen as intended. Seems like a bug to me.

[Carlosan]

All stencils show same issue ? Or only one stencil uploaded by you ?

[GimbalLock]

All stencils. I can get them to center in front of my model if I jump to Retopo room and back again.

[Carlosan]

Will you please try to delete option.xml ? something an option.xml corrupted give malfunctions.

3DCoat will create a new option.xml file at the next start. Maybe this solves the problem.

Is located on your \Documents\3D-CoatV4___ folder

Hi Carlosan,

Thank you for the suggestion. Unfortunately that didn't work. I can make stencil appear as intended like I described above, but that is just because 3dCoat deselects any chosen material when doing the switch between rooms. So when I'm back in the Paint room and the stencil appears correctly, the moment I choose a Smart Matrial (and of course resets projection to Camera after the material switches it to Cube Mapping), the stencil returns to the odd behavior.

Is the stencil not supposed to work full-screen with a smart material selected?

Can't you paint your object with the stencil tiled over the whole view?

Try this method.  The below worked on my end to center the image and tile it or move it plus resize.

Choose your smart material first. One reason is most default smart materials are set to cube mapping so  select "From Camera" in the Preview Options Panel.

Adjust the image size of your smart material to your liking. Center it , move it, resize etc... If you can not even do those  3  to a smart material image that is another problem addressed at the end of the post.

Turn tiling on or off.  Previous post picture. Test moving, centering and scaling again. 

Now select your stencil and it will now act as a mask for the smart material.

You can now adjust the stencil image but not the smart material image size, it appears locked. 

If you can not adjust your stencil image or a smart material image by itself,  then it is possible your 3DC installation is corrupt. 

If you re-install be sure to remove the 3DC folder under your  My documents folder/ user/ 3D-Coat xxxx ( your version)  manually. That is if you are using Windows.

Like I mentioned in my previous post, I do not experience the same problems you are having.

The picture shows the smart material image, and the stencil overlaying it. The crack mud type stencil. 

The images are tiled...

Hi Digman,

I can manipulate the scale/position/rotation of materials as well as stencils, but the preview visibility is acting very random and weird, and most of the time inside that off-center area I mention. Other preview-related things seem glitchy so I'll try to reinstall completely, wiping everything 3dCoat first, and see if that helps...

[GimbalLock]

Ok, I completely wiped 3dC and reinstalled. Behavior is essentially the same. On the first launch I chose to paint object and loaded the preset model. I made a strange discovery in the process that makes it useable, although in an illogical way.

Described below. I'm a bit of a 3dC noob, but this is not intended design, is it?

It's only with a Smart Material selected. Paint with basic color and Stencil works as expected.

I can not re-produce these errors.  Possible video driver problem. If you use skype for voice and screen sharing, I would be happy to go over this problem with you. Pm me if interested.
