  1. Hello, this is my first time trying out 3d coat and i' ve been bumping into the same problem on a particular model i'm working on. After i add some seams, change my uv layout and then press UV Unwrap some areas on my model become grey with no checkerboard projection on them and they also dissappear from my uv set. I have checked my model and cleaned it up twice by now, making sure there are no weird areas but i have no idea what is causing this. Any ideas?

    [Solved] UV preview problem

    When I adjust UV,another UV set can be select and move. This problem only occurs when select Vertices, Edges, Tweak. I use version 4.8.20
  3. I have symmetry ON and I unwrapped my model, then applied symmetry. This causes UV islands to be backed on top of each other according to the symmetry. I now want to move the stack of the UV islands. However, when I click on the island, on the top island is selected. Is there a way to select the UV islands together while they are on top of each other?
  4. 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

    UV Stacking

    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.

    Help with 4.8.10 uv

    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.
  8. 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.
  9. 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.)

    Multiple UVs Import

    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.
  11. 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.
  12. 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!

  14. As I was UV mapping a model yesterday I assumed that the Complex Checker orientation needed to be readable to be correct, but that doesn't seem to be right at all. Here all of the islands are rotated and flipped so that I can read the complex texture (I assumed that's how it's supposed to work): But the result had the opposite effect. I could paint and it would appear as I expected, but on the UV map, everything was backwards–flipped and rotated in the wrong direction: Starting over, I rotated all the islands so that they were upside down. (didn't need to flip anything, they were all already backwards): The end result shows that the painting is in the right orientation: Is it supposed to be that way? Am I always to assume now that my UVs need to be backwards to be correct? Anyone else experiencing the same thing? I'm using version 4.5.23C. Thanks!

    No uv preview

    Hi! I made a model of human model. In the retopo room I used Autopo and then i manually edited some faces that got wrong. Now i want to edit the UV, according to tutorials there should be a red 3d mesh in the UV preview window, but not for me. There is no UV preview in the UV room either. What is wrong? is this a bug or does the UV exist but is so messed up by the autopo that it can't be renderer? I heard something about that a 'face' are not allowed to have more than 4 edges. could perhaps that be the problem here? Some faces only have 3 edges while other have 4. Thank you.
  16. 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":
  17. 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 -
  18. 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?
  19. 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!
  20. 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/

    UV Automap cluster size?

    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?
  22. 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
  23. Texturing is central to 3D. From UV to UDIM to Ptex, it is easy to think one technology has just displaced another, but the reality is more complex. UDIM UV mapping has enormous popularity for texturing in the face of much newer systems such as Ptex (which works very well in its own right). While Ptex may still yet win the texturing heart of pipelines around the world, it has not yet become the dominant force. The article at FXguide UDIM is a way of creating a single linear number that identifies each integer block in UV space. You do this by defining a limit on the number of patches you can use in the U direction (the U-DIM) and then resetting U to 0 and incrementing V by one after reaching that number. i.e. fill in all the patches up to U=10, then go back to U=0 and go up a line in V. In fact, while UDIM could use an U base number, 10 is now the default and almost exclusively the only number used. The UDIM number starts at 1001 with the U=0,Y=0 being 1001. //note: Proper UDIM support in 3DC was implemented after v4.5 BETA4
  24. 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
  25. 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.
