Hi,
I use 3DCOAT primarily for 3D modeling.
I'd also like to use it for object mapping for use in animation software.
However, I'm having a problem exporting colors on an object made in 3 fusionned parts.
The object is a crank with three parts: a metallic part with worn paint, a screw, and a handle.
I've included a video to illustrate my problem: https://drive.google.com/drive/folders/1-APPVVrUEktXC-GIYLEcS67rNbhECM3u?usp=drive_link
Does is possible to show me the correct way to create a color map ?

Unfortunately, this new version does not take into account the "negative value" used by the "bas-relief" tool.
Do you think the next version will include a working tool like the old versions?

Bas-relief/undercuts will always be free, Molding will become payed after some time, now it is free.
It is very good news that the bas-relief tool remains free.
Until the bug is fixed, I will use two versions of 3DCoat at the same time: the 2021.30 whose bas relief works and the 2022.58 to continue my work and use the latest improvements.
Thank you for your time and long live 3DCoat! -
Hello dear Oleg_Shapo,
I have been using "3DCoat" for several years and I have 2 licenses purchased (for V4 and now the new version). So far I have never had a problem with this tool. I am not looking to make a mold but just to extrude with a slope as I have always done as for example when I need to fit 2 pieces as shown in this example: https://cults3d.com/fr/modèle-3d/gadget/boite-a-bonbons-halloween
So I really like working with 3DCoat and I hope that this bas-relief creation tool will remain free.
If not what would be the price?The name of this tool in French is : "Bas-Relief" and I use negative "angle de conicité"
-
Hello,
The "extrude" tool no longer works.
I often use negative values to get conical shapes, but with this version 2022.58 there is no difference between positive or negative values.PS: the tool works whell with the older version of 3DCoat

Hello,
First thank you for trying to help me and second I wish you a happy new year.
I tried to use the autopoto tool but I never have a PNG file result when I export.
The only way I found to get PNG files didn't convince me because I have a lot of PNG files and the 3D printer vendor only asks for one.
what am I doing wrong in the following video?

Hello,
Should I conclude that there is no possibility to export in color for 3D printing?

Hello,
Since the beginning of my use of 3DCoat, I only use the voxel and the 3D printing room for all my projects and I generally export ready-to-print objects to an OBJ or STL file.
I have no idea how the other rooms work because I don't need them. (paint, UV, retopo, etc...) and because I can't see the colors.
But today I need to send a 3D file to an external company in order to print something in color.
The supplier asks me for 3 files in order to print in color:
An OBJ file, a PNG and an MTL
For this project I prepared a file with separate elements and just changed the color of each one from the shader tools using the requested RGB codes.
But when I export I only have an OBJ and MTL file and the supplier can't print in color with that.
I've read a lot of tutorials but now I'm completely lost and asking for help to find a correct way to just get the PNG file.
Please how to export colored file?

Hi Carlosan, what is it "Feaure" ?

Quand vous travaillez avec les voxels vous ne vous préoccupez pas des arrêtes et des points, seulement du volume lui même.
Dans ce cas les arrêtes et points n'ont pas d'importance car tout le maillage est temporaire. Il ne sert qu'à visualiser le volume que vous sculptez.
En mode surface, dans le même espace sculpt, là vous pouvez vous préoccuper des arrêtes et des points, mais seul Move et Pose vous permettent réellement de les controler avec précision, à mon avis.
Non, si vous voulez travailler sur les arrêtes et le points avec la même précision que dans les autres logiciels que vous citez, seuls l'espace retopo et modeling vous le permettent.Bon il me semble bien ne pas avoir été assez clair sur ma demande, j'en suis désolé. Je réessayerais plus tard.

(Le présentateur me fait penser à Che Guevarra)
Je ne comprends pas bien pourquoi vous avec besoin de commencer par la retopo ? Il me semble que ça serait plus logique de créer cet object avec des voxels et de faire la retopo en dernier.Comme montré dans la vidéo de mon 1er post, je commence bien par l'atelier Voxel.
Si je bascule dans l'atelier Retopo c'est simplement que je n'ai pas trouvé d'autres ateliers ou visualiser les arrêtes et les points. Il y a bien le mode de visualisation "fil de fer" mais là non plus je ne sais pas exploiter les arrêtes.
Dans l'immédiat j'utilise soit le site "https://www.voronator.com" ou bien le soft Meshlab pour satisfaire mon besoin, alors que je pressent que 3DCoat peut aussi "voroniser".
Du moins je l'espère car à mon sens le mode "Retopo en Symétrie" donne un maillage en visuel bien plus correct.

Si je comprends bien vous voulez utiliser les outils de l'espace sculpt sur votre maillage retopo ?
Si oui c'est plus ou moins possible, (sculpt room : geometry menu > retopo mesh -> sculpt mesh) mais il y aura triangulation du maillage et vous n'aurez accès qu'aux outils de mode surface, et les outils live clay détruiront votre maillage.
cette opération n'a de sens que si vous vous contentez des outils Move et Pose, avec l'option "conform retopo mesh". cela vous permettra de bouger les vertices facilement.
Pour en ajouter, il faut le faire dans l'espace retopo, puis remplacer la copie de l'espace sculpt par une nouvelle copie si nécéssaire.
Il me semble donc plus judicieux d'oublier l'espace sculpt et de continuer dans l'espace retopo, où vous trouverez des outils d'édition puissants sans perdre les quads.En fait je m'aperçois que je n'ai pas expliqué le but final, au temps pour moi...
Alors en fait je cherche tout simplement à reproduire un effet Voronoi, un peu à la manière de ce tutorial:

Que voulez vous dire exactement par "les épaissir" s'il vous plaît ?
Et bien normalement lorsque des courbes sont créées avec l'outil "Blob" par exemple, ont peut simplement les remplir et leur donner une épaisseur.
-
Je me demande comment faire pour rendre disponibles dans l'atelier Voxel les arrêtes, les faces, les sommets, générées dans l'atelier de Retopologie ?
Ceci afin de pouvoir les épaissir.
Pour l'instant j'en suis là: https://drive.google.com/file/d/1BlxdKBpfxfoM3yTfImhMsOqcnL63S_P_/view?usp=sharing

Ok Carlosan, Gizmo origin is the solution.
From 3D Coat the gizmo is positionned at 0,0,0
But when I open it with 3Dbuilder it seems that it is at 0,4500,0.
So I change the origin that inside 3D builder then save it.
Now that work fine.
Thank you

Hello,
In order to decorate an helmet I would like use repetive pattern with the tool "curve".
But that works well for existing patterns and not for the new one I created.
The problem is this new pattern doesn't stick on the surface of the helmet.
I have several questions:
Does the "Curve" tool is the correct way for that ?
If not what will be the correct tool ?
If yes what is wrong with my method ?
And also how is possible to place the Red bubble of the curve tool at 0.00mm (front view) ?
I have prepared an short video to show you my screen.

Sometime I need to use a simple formula to define the size of something.
For exemple if I want a diameter of 25mm of radius I type 50/2 and the result is 25 that is good.
But if I type 77/3 the result is 25 that is not correct the expected result should be 25.666
What is the way to define the precision level ?

Try voxelizing your model to 5-10 million polys and then apply regular export. Decimation to 500k polys ensures excellent detailing for printing. You can also try decimating to 1mln.
Ok, I will try your method.
I thank you for your time.

Understood, it is clear.
You are right because usually my 3D printers sizing my 3D models.
In FDM printing process I have no problem of resolution because I print simples objects.
But in SLA/DLP printing process it is another story. I request lot of resolution and to do that I have two choices:
1) Exporting in OBJ at 85% of reduction: the size of the 3D model is around 1 GO that is to big for my 3D printer/slicer
2) Exporting in STL, in this case the weight of the STL is always 18.55 MO that is perfect for my 3D printer/slicer.
But it is not good for the resolution.
The only way I found with STL exportation it is to reduce the layer value. But if I reduce it so much 3DCoat crashes.
In order to not crashe 3DCoat, does is possible to predict what will be the minimal layer value according the size of the 3D model ? -
Hello,
I just tried with the latest version 2021.81 but unfortunately I have the same problem.
Maybe something is wrong with my computer because I also have a lot of memory crashes. (see my last post)
-
Thank you Yousung for this answer,
Unfortunatly I tried this tool lot of time with complexe or simple 3D model but everytime 3DCoat crash without error message.
I'm waiting another version before to continue.

Hello, In order to help me to define the weight of resin or plaster I will use to create the mold or the model, does a tool exists to give us the volume of the 3D model made ?
If not, is it possible to add it in a near futur ? (the volume will be give by 3Dcoat + the people give the density of material and the weight will appear directly, juste like other industrial CAD software)
-
Hi dear Carlosan,
Yes I have send the crash reports several time. But it seems that I have never receive answer or perhaps something is wrong with my mail adress.
I have just prepared a video to show the problem.

[Bug] Export the colors of fusionned objects.
in Questions & Answers
Posted
Hi,
I thank you very much for considering my problem.
Yes, renaming the layer was the solution, and everything is working correctly now.
For the future, I think I will avoid changing the names of layers to prevent similar issues.
Thank you again, and I wish you a happy Christmas!
