Image Texture node to color channel renders in shape of circular preview image, not as seamless texture.

[dan-at-gh]

Hi everybody,

When using an image texture node (browser drag and drop from disk cloud folder) connected to the Base Color of the Material Output node, the texture is applied as a circular preview image with black background. Just as it is shown in the browser thumbnails.

I would expect the texture to fill seamlessly the chosen mesh regions, not in a circular fashion with black background.

What am I missing here? Is this a misunderstanding from my side how to use image textures in ArmorPaint?

Besides: In the browser the Disk tab is working and showing previews of materials and drag and drop of the thumbnails is working. But from the Cloud tab it won't function, thumbnails are not shown and drag and drop is not working. Is there some configuration missing?

ArmorPaint is super! Best regards
Daniel

Hello Daniel,
you used my instructions for 0.9. If you've done everything, you'll have a krom folder with armorpaint.exe in it (8.) and you've also installed armorpaint in the system (9.).
It may be that the cloud function only works with the armorpaint version in the krom folder. Well, that's how it is for me.
Please test the version in the krom folder. And always wait a bit. The connection to the cloud and the update takes some time.
The cloud function works for me with the 1.0 alpha too. But there's the strange red cube. :)

Thanks for your reply.
Yes, actually I didn't completed step 9, but now I also completed all the commands from step 9. When pressing the Cloud button, a red message box says:
Error: Check internet connection to access the cloud

In the terminal I can see the following lines:
/usr/share/armorpaint/krom/./data//download.bin: permission denied
arm/Console.hx:69: Error: Check internet connection to access the cloud

I tried to check the permissions of this download.bin file, but couldn't locate it so far. Also the path to this file doesn't look familiar to me.

Do you think this is related to the problem of the circular texture mapping or not being able to drag and drop like it is shown in the video you mentioned?

To be honest, I have no idea what isn't working.
Point 9 obviously doesn't make sense either. Armorpaint isn't in the krom folder. That's why it doesn't work. You can undo point 9 (it's exactly stated in the text). I definitely have to add that to my PDF.
So start ArmorPaint in the krom folder in any case. When you start the cloud for the first time, ArmorPaint creates a cloud folder with all the icons in the krom folder. At least that's how it works for me.
In the picture above, you've only put the tiny icon file on the mesh. That's not the goal.
But you have all the icons. That means the cloud is working at least partially. :)

We both have Ubuntu 24.04 and the same 0.9.
I have a krom folder in the home directory. If I double-click it, ArmorPaint starts. (Or just start in the terminal.) If I click on browser and then click on cloud, I see 5 folders. Click on the materials folder, then polyhaven and then I see over 40 materials that I can drag and drop onto my cube.
So that doesn't work for you?

And after I've dragged a material (e.g. asphalt-0-3) onto the cube, there is also a material in this cloud folder (asphalt-0-3-.arm).
I can then save the material somewhere using File ->export textures (then I have 5 files).
Have you tried the cloud in the 1.0 alpha?

Ah, ok... You are right, in the picture above by mistake I only put the tiny thumbnail image of the material onto the mesh. I took this little image from the browser and the Disk location (not the Cloud): ~/opt/krom/cloud/materials/polyhaven. I understand, that this is not the way it works.

But on the other hand, when clicking Cloud in the browser I can see the 5 folders -> materials -> polyhaven, then I can also see over 40 material slots with names but no preview thumbnails:

I was wondering if there are only the tiny preview images missing, but when I try to drag and drop a material onto the default mesh, nothing happens, so this is not working somehow.

I can see from the terminal output, that armorpaint is downloading material data, including icon image files:

/home/dan/opt/krom/cloud/materials/ambi 100%[=============================================================================>]   9,32K  --.-KB/s    in 0s      

2025-01-28 08:44:18 (296 MB/s) - ‘/home/dan/opt/krom/cloud/materials/ambientcg/multiangle/Wood063_4K-JPG_icon.jpg’ gespeichert [9541/9541]

But these icon files don't seem to work for me in the Cloud browser.

For Armorpaint 1.0 alpha, material preview thumbnails and drag and drop is working fine!

To summarize:

• ArmorPaint 0.9: no preview thumbnails in the Cloud browser,
• ArmorPaint 0.9: drag and drop of materials not working,
• ArmorPaint 1.0 alpha: preview thumbnails and drag and drop of materials both work fine.

I hope that you can somehow use the two versions for yourself at the moment.
The cloud is helpful, but not absolutely necessary. You can simply download something from polyhaven and use it.
Or you use the cloud in 1.0 alpha and then you always have the .arm files of the materials used on your computer. You could probably just import them into 0.9.
I think it's great that you don't let the problems put you off and keep going.

I tried to import a .blend file from polyhaven into ArmorPaint-0.9, but that made the application unresponsive using 100% of cpu. Probably my hardware environment with dual gpu causes ArmorPaint to be this unstable, but this is only a wild guess so far. At least in the past I had some difficulties with the dual gpus in combination with Linux, although e.g. blender is running fine.

I think it's great that you don't let the problems put you off and keep going.

ArmorPaint is definitely worth that, thank you.
