3DCoat 2024 development thread

Small bug about primitive (for modeling room),  each primitive use different measurement unit so without user check and memorize, to generate size correctly with value, may confuse user who use those. 

eg If I generate sphere and set radius 1000 it generate this size.. (it seems count my unit setting = meter and scene unit or voxel per unit (I set it as 1000))

 if I generate cube and set size as 1,  it generate this size (it only count my  unit = meter setting)

Then which unit may used for those primitive setting value change by each primitive,, it  actually confuse me to set size correctly.. sometimes it come too large or too small with input same value.

(of course to generate each primitive I do not change any scene or unit or voxel count settinig, keep it as my default setting)

@SERGYI Is there anyway you can tell us how to generate some debug info for you in linux?

This week I will try to update my Linux to 21.04 to see on my machine what is going on.

I'm trying to create series of little assets that are presented as a little scene (for people to take apart and rearrange or use only one or the other of the assets separately).

Now, if I create them separately in different .3b file all the way to the painted low-poly, it is difficult to reimport them in a single scene in 3d-Coat to scale/rotate/move.
3d-Coat doesnt make the scale/rotate/move too easy (tweak room or via retopo room), but still, it can be done.
Now what the problem is is that when you import a paint object, you have to load textures individually. Moreover, you can only import certain types of textures, the ones that are available from Textures menu>import, which may not comprise all possible workflows.

I am curently trying a workaround : I am sculpting everything in a single scene, or sculpting them separately, moving them to the models panel, and summoning the new ones in the final scene to organize them as sculpt object.
I plan to retopo/bake/paint them all later inside this one file, which will later make it easy to export all at once.
EDIT: The problem with that is that I am doing all the fun things (sculpting) first, and when I am done I will have to do all the boring stuff without being able to take a break doing fun things.

Now, I was thinking, what if 3d-Coat supported those .glb / .gltf formats, which contain both mesh and textures, it would make things much easier to exchange between software and between 3d-Coat projects, wouldn't it ?
Is there any chance that this may happen in the future ?

Hi,

 

Does anyone know what is happening here? Is it a bug? Apologies if this is the wrong place to post.

This is the "baked normals" of my mesh. This is the mouth of a human head where the effect is the worst but it is happening in varying degrees all over the mesh. It should be smooth. For example, look at the weird lines and squares around the lips which I feel should be smooth like in the sculpt room but can't make it so. Thanks for your help.

I have one question about importing textures.
Is there a way to keep areas outside the UVs when importing textures?

3DCoat blows all textures outside the UV area of the model when loading textures. 

Here is a model with the original texture and some UVs unfolded.
(Assets purchased from the Unity Asset store.)

They are efficiently placed to create various assets with one texture.

Import the model and textures into 3DCoat to edit the textures of this asset.

 

 

Then everything outside the UV area is blown away.

I want to work on some areas, but keep the original textures intact.

@MVICHi, try bake it using another shader

Hi @Carlosan ,

Thanks for the quick reply. I take it you mean you change the shader in the sculpt room? Any you would recommend to pick?

I think recent 2021.24 tweak about scene setting and scale things again. 

Because I import same obj as retopo mesh with use same setting. 

but now it change size drastically.  To confirm it, I launch 4.9.72 then set setting like this, and use same setting for 2021.24

Then import same object file, as import retopo mesh, now it drastically change size between 2 version. (maybe new 2021.24 change something)

I did not see issue about 2021.22  (it is version which I test those scale things, then it worked)

test please with this monkey obj.  simply import as retopo mesh then compare with those 2 version.(use same setting for scale)

grid setting is same. (so 1 unit length = 1 meter), it effect exported mesh scale tool. so now if I export mesh as 1 meter (at least in 3d coat 2021.24)

I got huge mesh in blender .  (only about this version exported mesh)

====

OK after I re-launch and do same test now import export show same size.. do not know reason though.

so when change scene setting first time, it not correctly up-dated? I actually get strange size mesh in blender when I first test with 2021.24

but now it seems return correctly.

The only way to keep outside is Photoshop or similar. Magic wand with grey color+old texture on background.

- Picker tool (that may be activated via the hotkey V) now works correctly over the sculpt layers. It also got additional functionality. First, yo may choose to pick the color from the screen always in the tool settings. Second, even if this option disabled, tap V second time over that same color and second tap will pick the color from the screen. The first tap takes the color from the layer if available.

I can't find the "tool settings" for the color picker. Where is that ?

Thanks.

Why does the Scrape tool not remember the "soft scrape" setting from one session to the next ?
-Untick "soft scrape"
-close 3d-Coat
-reopen : "soft scrape" is ticked on.....


settings that are not remembered are so annoying. Someone mentioned others but I'm not sure I remember, I think Cuda and related options ?

It is in Paint room->Picker tool

carve tool have random rotation 

its normal calculations are all broken when painting on surface

Please explain the sequence of commands. Because the object is really small. And in my tests, it works the same way in 4.9 and now. Maybe I do something differently.
