Hey guys, I'm sure this has been asked before, but I was curious if there is a button that will auto-fit the UV islands to completely fill the UV tile/preview window. I have attached an image below of an example I am working on now. Pressing "auto-scale" didn't seem to do much. Thanks! -Davide Foundation_Walls_Bottom.3b -
Hi, In the UV room is there a way to sew together seams?

Hey Gang, Just wondering if anyone knows a way to fill only 1 UV island at a time in the 3D Viewport with freeze or just colour? Would save me a lot of time instead of hunting down the island in the Texture Editor. The program got into a weird state the other day and was doing this, and I'm unsure if it just bugged out or I found it by accident. Cheers -
Hi folks, I have a question with regard to UVs. I have read other threads on a similar subject but found now solution. - I am using only 3DC and I have a Scene I have done in the sculpt room. Its made of 3 separate Meshes. - I make a Low-res decimated version of the the scene and export that as an .obj. - Move over to Retopo room and import that Low red version via the 'import retopo mesh' - Once that is done I do all the seems on each mesh, unwrap each mesh. all on separate UVs (or at least I think it is. they are not overlaped in the 'UV preview' - Then Bake the normal to tranfer over the detail from my High Res to the Low Res Version. and here is where I have my issue - I move over to the paint room and even though on the Bake process it asked me about the three UVs I wanted to bake. in the paint room they are just stacked on top of each other...why? (Note, I looked in the UV room and they are stacked in there too and cant seem to find a way to separate them.) I am miffed :S Cheers.

I'm revisiting 3dcoat and the latest update to 4.8.10 has given me a weird bug. The mark seams tool does what it wants. I cannot use it on the edges l'm hovering over with the mouse, it'll always maybe select an edge loop around 4 faces below where l'm selecting. It also wont select individual seams and instead stay in edgeloop mode. Please help.

Hi there folks, I know similar things have been asked before and I have read a followed those threads to no avail so I am starting my own post with a hope to get some help on the issue. Here is my workflow. I sculpt a model in the sculpt room (Made of more than one Object) > Decimate the mesh's a bit > Import for Per Pixel Painting > Then it squashes all my object into one UV. I would like 3Dcoat to take the separate meshes within the Exported .obj and place them on there own UV Island. Possible? Cheers.

Hey, Currently in the process of unwrapping a model. I'm trying to use the copy and paste uv tools to overlay some uv tiles that I want repeated. See below. However when I attempt to copy paste them nothing is happening despite them being completely identical? This isn't the only uvs its happening too, it's the same with all other identical uvs.I've also had this happen on older files too. Below is a pic of the object in mention. I'm running the latest version. Any help would be greatly appreciated. Thanks.

I`m moving between applications in my workflow (sculpt in 3D-coat, paint in Substance Painter). I have heard that the following is possible, though I`m unsure how exactly. I want to : 1. Import a mesh (originally sculpted in 3D-coat, but textures are generated in Substance Painter) 2. Import multiple texture sets for said mesh (from Substance Painter: they all belong on the one mesh, but for different "parts", and therefore needs to be merged since it can`t be done that way in Substance Painter) 3. Somehow combine the textures into a single UV-tile (that can later be applied to the mesh inside of e.g. Maya). 4. Export (... the newly combined texture as a single file.)

Добрый день, Я активный пользователь 3D coat и на днях у меня возник такой вопрос. Можно ли добавить в Скульпт рум модель с уже готовой рвзверткой чтобы потом расклонировать её повсюду с помощью Instancer? Интересуюсь вот почему. Я собираю сцену из модульнных объектов (домики, заборчики) прямо в 3д коат , затем экспортирую её целиком во внешний рендер. Я знаю что я могу процессить каждую модель отдельно, сделать развертки и экспортировать в рендерер по частям, собирая сцену там. Но хочется работать над дизайном сцены в 1м пакете, не прерывая поток. Плюс ко всему, не хочется ретопать всю сцену, а только по 1му экзепляру объекта, с последующей автоматической подменой всех инстансов в сцене. Предположим такой пайплайн. 1. Моделим несколько домиков в скульпт руме 2. ретопаем их и разворачиваем в ретопо руме 3. забираем развернутые модельки в скульпт рум обратно 4. заменяем воксельные объекты на лоу/мид поли из ретопо рума. 5. экспортим всю сцену в рендерер, настраиваем материалы. Такой пайплайн позволит не только ускорить процесс сборки сцены, но и ползволит улучить качество. Если есть способы это сделать сейчас, буду рад если кто-то мне расскажет. спасибо!

Problèmes avec la fonction "Défaire-Unwrap"
ChristianClavet posted a topic in Discussions sur 3DCoat
Bonjour, J'ai quelque chose qui arrive sur mes modèles récemment. Il me semble que toutes les coutures sont bien placés, mais quand je presse le bouton "défaire-unwrap", je pert quelques polygones de la surface de ma carte UV. Voici une image, quand je fait un AUTO-UV, tout semble correct: Et voici ce qui arrive si je presse le bouton "défaire": -
I'm new to 3dCoat and searching for the best way to do good, clean well-aligned UV Mapping so that the borders are synched-up perfectly (doing figures). The other posts are a year old, and most of the pages are NOT FOUND - I'm open to hearing suggestions and seeing links for the best clips on these subjects! Thank you - -
У меня есть Low-Poly модель с симметричными боковыми частями, для этих частей сделаны одинаковые UV- островки. Эти Островки полностью накладываются друг на друга на развёртке (overlap). Как правильно запечь АО с High-Poly для этого Low-Poly объекта так чтобы два раза не запекалось на одно и то же место на текстуре? Чтобы потом АО не было более чёрным для элементов которые накладываются на развёртке?

Automap UV feature is fantastic, very impressive results in testing. Only issue similar to other automap softwares is small islands, sometimes these are single triangles. This usually seems to be because algorithm does not take into account size, only other metrics like angles? A min triangle or cluster radius would help. This could be separate from automap and just another uv tool that looks over existing seams/islands and merges/welds small island to neighbouring ones. This is useful for avoid many islands on small noisy areas of mesh. Maybe it will need some cuts and islands in areas like this, however main advantage of automatic uv feature for me is making UV islands of the bigger broader shapes/volumes. Provides a good starting point. Presently either do manually or have to cleanup hundreds of islands. One mesh have 3k islands but only about 200-500 are reasonable size the rest need to be removed/merged. EDIT, sorry just notice on mobile there is feature request section, could this thread be relocated there please? http://3dcoat.com/forum/index.php?/forum/14-feature-requests/ -
This auto uv map feature 3D coat looks very good! One small issue was in noisy areas of mesh it made many small islands, I am wanting to just uv unwrap the broader/bigger surfaces automatically as a starting point. Is there anyway to control the result so that islands must be of a min size/cluster? Or must I go through afterwards and find all these tiny islands to merge/weld them back manually afterwards?
-
I'm trying to mark some UV edges and cannot because the model goes 'behind' another mesh. Is there anyway to 'hide' the mesh associated with an island OR use wireframe view mode in the UV room? Choosing view Wireframe doesn't work for me in 4.8.03

Hi everyone! When I uvmap, sometimes certain meshes are doing this strange thing of having one or more polygons plain grey. They also don't show on the UV map islands! I've encountered this problem twice before: once, I solved it splitting a polygon that had several vertices in more, simpler polygons; and the other time it was a rectangle and I just couldn't get what was going wrong. I've no idea on why this is happening (in this specific case is also a triangle, so it's clearly not a matter of complexity) and I'm attaching a screenshot to show you the situation! Thank you for your support!

[Solved] Best way to prepare voxel mesh for UV painting
Metin Seven posted a topic in General 3DCoat
Hi, Sorry for all my questions, but I'm still exploring 3D Coat, and loving it. I was wondering: If you take a voxel object straight from the Sculpt room to the Paint room, you'll be painting with vertex colors. What's the best / easiest way to convert a sculpted voxel object to an automatically UV-mapped mesh that's ready for UV painting in the Paint room? I assume the key room for this is the Retopo room, but what steps should I take if I want the voxel object to be meshed and get UVs in stead of going through retopology? Many thanks, Metin -
I'm getting this issue "The square of the UV set is too big." I don't know what could be causing this error. I've imported other models exactly this way before with no issue, but there seems to be an issue now? I attached my unwrap in the images. The poly count is 3,824 tris. If anyone has any ideas please let me know. -
Keep the original texture after unwrapping edited model
Jose Acosta posted a topic in General 3DCoat
So I imported a low poly model and cut off a small portion of it. But when I unwrap it the UV Map is completely different from the original one and when I import the texture it had before it's all messed up because it doesn't fit the new uv map. So is there a way to make changes to a model and still have the original texture wrapped around where it was before? It's really frustrating not being able to keep the models original texture after unwrapping. -
I would post this in the appropriate forum section but I don't seem to have the permission to create a topic there. There was a similar feature request from 2014 on Trello here: https://3dcoat.com/mantis/view.php?id=1102 This request is for UDIMs(which 3DCoat doesn't seem to officially support and treats as additional UV sets). We have a 1MB FBX asset, when imported It uses around 40GB of RAM to support 20 UDIMs at 4k. We'd like to work with 8k but the way 3D Coat seems to handle this is keep all textures in memory even if no colour data is painted on or loaded in via textures? We already have the 8k textures from an external bake and would like to bring these in to do some post work with 3D Coats tools, the required amount of memory is a bit of an issue. This feature request is about importing multiple textures at once(our UDIMs), if 3D Coat supported UDIM layouts properly it should be able to easily infer the appropriate textures for each UV set(which is named by it's UDIM ID in our case). All that needs to happen is provide a list of textures or a folder containing them, remove the extension from the file and look at the last 4 numbers for the UDIM IDs to match their UV set. I considered trying to implement this via the Angelscript support, but did not see any information on how to perform these actions with the docs I came across? Additionally to handle memory issues, would it be possible for 3D Coat to allow a disk cache/scratchdisk to be set by a user to write/read the individual textures from and to until the user actions a save? This way 3D Coat could perhaps use a format where it only reads in the mipmap data of an appropriate resolution or separate files only keeping textures in memory when they're in the viewport and proxying others based on viewport culling or screen/viewport size, ie 512 or 1024 px maps could be used elsewhere on the model data, and keep memory usage down, only presenting/using actual texture when applying paint or some other conditions? I'm not sure how the software Mari or others might approach it but it'd be great to use 3D Coat for this workflow. We have one asset with 100 UDIMs that just wouldn't be possible to work with in 3D Coat beyond setting very low texture texture resolution and manually adjusting the size and textures loaded in. Is there a way to fund features/priority in any way? I can understand this may not be as useful/valuable to the existing 3D Coat userbase much, it could attract a new community of users that do have these needs.

Hi all, This is another question where I'm struggling with workflow. I built a complex model in Cinema4D that is designed for subdivision. there are a lot of really fine sharpening cuts. These make it somewhat difficult to build the UV set for, as I have to zoom way in to get exactly the right edge. Would you suggest doing those sharpening cuts once I've exported from 3DCoat? Or am I thinking about this wrong? Thanks! Justin

Hi All-- Hope all are well....incredibly grateful if you can tell me how to accomplish this...and ASAP I'm building out some models in SILO3D--and I'm using 3DCoat for UVing so far. I absolutely love it. Here's my trouble: I've marked up my mesh in the OBJ (silo) w/ some simple Materials....then I head over after UVing (3dcoat) to substance painter where I replace those simple MATs w/ glorious procedural ones. Problem is when I hit "APPLY" in the UV room----my material names all get nerfed back to vanilla (all one color, one same mat). What do I need to do in 3DCOAT so this doesn't happen? I imagine I need to tell it something in the paint room etc before I hit APPLY UVs. I'm on a tight deadline so this will hugely help my workflow. Thanks so much--and if you wanna call and walk me thru it I'll definitely return the favor. Roger

Hey folks, I have a question about Exporting Textures. So, I have a finished model that I have unwrapped and UVd and then painted in the paint room. But when I brought it into Unreal I am not happy with the resolution of the texture and I am already at 8k. (was hoping to get it all on one UV) Now I have gone back and split the model into separate pieces and am hoping there is a way to import them individually and bake/apply the previous painting I did to that section, OR. Do i need to paint all these separate parts again? please say it isn't so!

Hey all - new to 3d coat but LOVING it - But! Today - I can't for the life of me figure this out. I unwrapped everything and rearranged everything on the UV map... All great - Then realized my seams weren't right. Even tho the 'colors' of islands changed when I removed UV path and added UV path (using UV path tool and ctrl enter) - I thought that's how you do it? It looked right color wise: But still - when I zoom in I have this: What the heck is happening here? :-( If I unwrap it - it goes crazy. Stretches that area like crazy. So I'm pretty lost as to how to get it to work. Any ideas? Thanks!

Hey, folks, I just want to share some work we are creating here in Brazil using 3D-Coat on an online training course focused on characters. It's the first one in Brazil! Until now, we are working with everything that 3D-Coat has to offer, from hard surface to organic sculpt. The classes about human characters (cartoonish) will start in a few weeks, so until now we are starting to learn the software creating some robots and weapons. Hope you like it and will update here soon!
