its not a bug .. 
the color picker chooses between albedo and real world colors ... 

 

for example if ou see something on your model and think i like that shade the first "V" shows that color ... the v again shows the actual color without lighting or glossy etc...

 

grey shows up due to the bake layer below ... if youre landing on an area without color it will be greyed out as it has no information to show

Okay, so it's not a bug. However, in the process of painting and choosing colors very fast (brush-pick- brush-pick-etc.) I constantly run into the problem of sampling grey, just because I sometimes press V twice very short after each other, beacuse I realise I did not have the exact right color.
Is there a workaround for me?

I can't open a folder -(group layer) with a mask. Video:

 

 

EDIT: Okay, so if I click the group icon then it expands, but clicking the arrow does nothing. So I guess it's just confusing to have an arrow that's inactive, but when the GROUP doesn't have a mask it's active, the arrow really expands the group.

I stand corrected. I tell others to read the tool tips and I failed to do it myself.  

There is a lot the V key can do now but I am thinking of some suggestions to offer.

Hello 

I would like to point out a problem in the Paint Room.

I´m using 3DCoat 2024.20, as well as 2024.22.

Windows 10 Home, 32 GB RAM, 2 TB SSD HD.

There is enough space on the HD and there is enough space in memory.

I do my constructions with Sketchup 2017, export the model without texture as Collada file. Convert the file by external program to OBJ file.

When importing the file to 3DCoat by PPP, I do the "Auto-mapping". Texture size is 1024, "No Center Snap".

At first glance the file seems correct.

BUT:

When I disable all layers, there are still fractals to be seen.

The fractals are only in areas which are very thin, compared to the total dimension of the object.

The problem is that these fractals can´t be deleted, overwritten, painted or anyhow edited. The biggest problem is that these fractals are always on top and disturb anything you do.

On the picture you can see that all layers are disabled, but there are still the fractals (lines) to be seen.

Thank you all for any kind of support or solution.

Best regards

Walter

Check on UV room if there is some faces outside the 0,1 coords of UV space.

Dear @Carlosan

Thank you for the fast reply. There are no faces outside the 0,1 coords.

I think the problem comes from the automapping software in 3DCoat.

When I import the model over and over again with increasing texture sizes, the fractal areas are getting smaler and smaler.

We already had been in this discussion in May and you told me to contact support with the problem, but from support there was no reaction. (My post in May contained also some other facts.)

So because this problem is realy causing some problems on my side, I reposted the problem here and I will also contact Andrew Shpagin directly as he proposed this on other sides in the forum. I think this is a problem of general interest.

Thank you very much for the support.

Best regards

PBR Textures. If I modify a parameter and I dont like the out come I hit the reset. Then I get a message that the texture is broken. I find the correct Smart Material and click. It does not reset the texture. The texture has been written over. The texture cannot be reset, it will not restore to factory default either. I need to uninstall 3dcoat,  remove all folders in both Program File and in document and the reinstall 3dcoat.

Hello there ! In the latest stable build of 3DCoat 2024, I face this curious issue :



Is this known ? Is there a fix I should apply on my end ?
Thanks for your help !

Also another bug : the picking tool seems to evaluate the cursor color, or pick at wrong depth in the ZPass of the renderer. I regularly have to pick again because the picked color is grey and not the one I see under the picking tool, it's a really strange bug

[Carlosan]

Is this info in the popup tip related ?

Sampler Tool. Extract the Color, Glossiness, and Depth from the surface of an object. Use the V hotkey to select the primary color and depth outside this tool.

You can change picking preferences using this tool.

Use H to select the top layer.

Pay attention, if you will tap the picker hotkey twice over the same color (like the layer color) it will pick the color just from the screen.

In this way you may easily choose the right color, from the object or from the screen.

[Vexod14]

I guess the issue comes from that "twice picking". Is there a way to prevent this option from triggering ? It's disabled in Tool's options pannel, but still fires it.

Hi again !
I just found a third bug : 

when you add a layer mask, it becomes accessible for any layer (but can't mask any other layer than the first one it was created for), still it's possible to delete it from other layers as well and if so, it deletes it for the first layer. There are two design possibilities here (both are okay but I'd prefer the first one, cause it's more versatile & permissive) :
1 - you want to let user reuse an added mask, then allow this mask to affect any layers using it and in case user "deletes" a mask on any layer, just remove it from that layer, not from every affected layer.
2 - you don't want a user to use an added mask, then prevent user from accessing the mask outside the first layer it was added to.

I would also like my choice of color picker to be honored, either by way of a Preference, or to simply have it saved as a workspace setting.

The one question in my mind with the "V" key "mode" toggle (i.e. alternate taps) which it would be good to clarify is whether the toggle is between "Screen" and underlying texture value, or "Current Layer" vs "All Layers".

Just throwing out a tip: if wanting to sample Albedo color off the model, even with "Pick a color from the screen" on,use View > Flat Shade because with Smooth Shaded, it will pick up the shaded value -- in this case, not what you want.
