  1. I'm starting to get a bit more familiarised with how 3dcoat works. I'm just wondering, how does one duplicate an object from the paint room? Let's say I've already sculpted an object in the sculpt room, bring it to the retopology room to retopologise it, and then bake it to paint. One way I figured out is to bring the retop mesh to the sculpt room and duplicate it in the sculpt room, but what if I just made a small change, for example, add a hole to one part of it. Is there a way to copy the same retop mesh and keep the same uv maps without having to retopologise the new duplicated mesh?
  2. There are multiple instances of this happening to me. Particularly in the retopo room placing seams on the mesh. Please fix this as I don't have an autosave that has the progress
  3. 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://trello.com/c/VaktmiiU/192-import-support-for-multiple-uv-maps-and-multiple-texture-images 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.

    Export a single texture sheet...?

    Hi Is it possible to export a model's textures into one single sheet? I have a model all textured and ready to go back into 3ds Max, but when I try to export the textures, they're done individually. When the model was first brought into 3D Coat, all the UV islands were on the same sheet, but they could be isolated within Coat based on its material IDs. Thanks

    Здравствуй. Объясните, как правильно делать УФ. Мои текстуры очень плохие. Посмотрите на фото. https://ibb.co/yFGPhJY https://ibb.co/c6pwPPW https://ibb.co/5Gs5FB7 https://ibb.co/DLfmCnK https://ibb.co/L8Q3XdD https: // ibb .co / 5MNYTdv https://ibb.co/M8Y9zRn https://ibb.co/GcmcHnL
  6. I've never had this issue with prior version but with both the latest update of 4.9.15 & 4.9.17 the UV unwrap feature not working properly. I'm working with a 30,000 poly model and 3d-coat freezes for like 30 seconds every time I mark a seam or edge loop during UV unwrap. The issue doesn't happen when I use UV Path features. It has been doing this for hours. I might get a rare snippet of time where I won't get any brief freeze ups. I mainly work in the retopo room but I tried it in the UV room and it freezes up there too. I normally run GL mode in the because my computer is fast enough but I might try DX mode to test.
  7. Hello, I wanted to make a Low poly version of the hilt of the sword, but after retopology I get black game. How to create a low-poly model correctly? What is my mistake? My actions: 1) High poly model 2) I impose having noticed on the model 3) I apply having noticed 4) I click "Auto-mapping", "Sharp seams", "Expand" 5) I use baking 6) Total / Low-poly model How to create a good low-poly model?
  8. Hello. I'm looking for help. So here is my low-poly mesh, and it looks fine in 3d-coat. (pic 1) But if we take a look at it's normal maps (pic 2), we see it's being split at UV-Island edges. If I understand correctly those edges should not be there and they seem to cause wrong look in 3ds max or another software. The question is: am I missing something? Why does 3d coat break normal map on those edges? How do I bake it right? Tried switching GL and DX versions - to no avail. Tried different baking presets (for 3ds max, for Unity etc) - all the same. (There is another thread on this forum where a guy had similar issue, but that solution did not work for me (He had to update 3d coat and switch GL to DX)) Thanks in advance!

    UV Island problem.

    Hi! I have a problem with my model from 3ds Max. When I imported it, a face of the mesh in 3D Coat not match with the UV that I created in 3ds Max. Why!??.Exist any way to marge the face with the green island?. Thanks!
  10. Hello, I have a problem with the import of a file in the UV Room. When I import it as an FBX nothing appears (shift+A doesn't make it appear either). However, when I import it as an OBJ some faces simply disappear! The file is a pro boolean collapsed to an editable poly (mentioning it because it might be important) from 3dsmax 2020. I have tried changing the FBX to 2012, 2018, 2014... and to ASCII from Binary but nothing seems to work. BTW I am using 4.9.05. Can someone please help? Thanks!
  11. Hi guys! I do need urgent help here, so please consider this: I have a turbosquid .obj file (purchased legally) and I need to open it (flying dino) it's an obj. It has UDIM style UVs 3 tiles to be exact: 1001,1002,1003 and everytime I try to open it with different settings (default import, clicking import tiles as UV sets etc) I have no luck. First I had crashes, but that was due to having multiple mesh islands combined having overlapping UVS and multiple UV sets (probably a no-no) solved that. I can import the single mesh piece finally but now at least one of three tiles gets abnormally scaled in U or V direction?! making it useless. The best result so far was having two intact UV tiles 1001 and 1002 but the third tile for some reason goes nuts. if anyone can open it in any 4.x version of 3DCoat I'd be greatful to learn about what I'm doing wrong. Thank you for any and all help: The .obj in question is here: p.s: I'm using the latest 4.9.04. version. And the model works fine in a special UDIM branch of blender (all UDIM tiles are intact), but I'd rather paint textures in 3DCoat for obvious reasons. ptera_body.obj
  12. Hey Guys, I'm just wondering if it's possible to merge paint objects, or export with one material set? as currently i'm getting 10+ material sets in substance when I only want one, and I know it's because I have multiple paint objects. Any help would be appreciated, cheers.
  13. Hi, I exported 2 objects from my blender scene to 3dcoat by shift-selecting and using app link for 'per-pixel painting'. Both the objects are already unwrapped. But when transferred to 3dcoat, the bigger object has this noise, and upon inspecting I realized it has the materials but no UV's from my blend file.. any ideas what might be the issue here? P.S.: I've already tried treat materials as separate textures and Import tiles as UV sets but no luck
  14. Hi, So as you can see from the image I am making a blaster which has many separate pieces. It has been retopo-ed and UV unwrapped to one map. Due to size differences, the only way to get clean bakes is to do them individually and tweak the bake depths according to need. I assumed that when I baked each object, 3D-Coat would place the result into one map also, but it creates a separate UV space every time for each piece! I then have to merge the new UV map into a single one, which takes AGES on an 8k map. This is a very poor workflow. Am I missing something? Is this really the only way to bake multiple objects into one UV set in 3D-Coat? Please help.
  15. Hello. I have a situation that seems to arise with 3D coat, where I've modeled something in the Voxel Room, and right clicked on it to send it to the Retopo room with Autotopology...tweaked the topology and even UV unwrapped in the Retopo Room. The problem is that the UV set doesn't show up in the UV Room, nor can I see anything in the Paint Room. What am I missing in the workflow? Thanks.
  16. Hi - I'll admit I've got confused over this, and not for the first time. I'm working in Lightwave 2015.3, and 3DC 4.8.25(GL64). I open an object into the UV room, and that contains two meshes with two surface material names, but no UVs yet. The dialog in 3DC offers a UV set per material, so I click OK. But once open, only the first material that was in the list gets a UV set. The meshes are there, the surface materials are there, but only one set. That's the first confusion. The second: are UV sets actually separate UV maps, that can be exported, or are they only a UV management tool within 3DC? In addition, when I create a UV set, it adds a surface material of the same name to the list, when the surfaces are already named. When I export the meshes again, in LWO format, only the first listed UV set is exported as a UV map; I was assuming that UV sets would export as separate UV maps. Obviously that assumption was me, and seems incorrect. I have checked the docs and watched several vids, but not found anything covering this whole process. Surely on import, if 3DC offers to create UV sets per surface material, surely they should appear in the UV set menu. Likewise with exporting the model, and the UV maps created in 3DC. Would appreciate any insight. Thanks.

    UV Mapping Etiquette

    Hey guys. I'm a noob and need UV help. I'm making a superhero body suit for my Daz gen2 model by using a daz gen2 model. I decapitated him and cut off his hands and feet. I retopologized to 2000 polys in 3D Coat. The result is actually pretty awesome in terms of topology for the auto topologer (and I haven't smoothed it out or done any of the other magic things you can do in Coat.) But it's a single cowskin lookin thing and in 3d Coat it shows that there's mild overlap and stretching. Now this is not how anyone who makes tutorials on UV mappings that I've seen makes their UV maps. They make islands or clusters with seams and stuff. And I'm okay with that. But my paint is going to have this hexagonal geometric pattern like armor or whatever. I want the hexs to be as uniform as possible as my superhero is really buff and this leads to a little stretching. It's way better than it was but I want to make something I wouldn't be embarrassed to show to non noob animators. I'm worried if I put a lot of seams in then it'll cut off the hex pattern at the seams and my guy's paint job will look crappy. With this model the there is some distortion though it's not major. Before the darn hexes varied in size very visibly and now you kinda have to look for it. And again, I can make it better in Coat manually. But should I cut the bodysuit all up with seams. I'm probably going to make the collar a separate island because it has detail and I want to try making it huge in UV space. But that's just me trying to figure stuff out. So is there like a formal best practices way of making UV maps that I should follow in weird cases like this. In fact does anyone have a suggestion to a really deep study of UV mapping. I don't mind paying a few sheckles for a book. But paint should be pretty. I'm getting there but I don't think Pixar would be happy with the kind of Uving I'm doing....though that's not the best example in the world. Don't they use PTEX?
  18. Hi ! I painted my model without using retopology and UV mapping. It is possible to export the texture in this way ?
  19. Hello i have a mesh with one uv tag coming from cinema 4d and i want to pick spesific UV islands and transfer them to a different texture set, essentially creating an extra uv tag for these objects. Can do that in 3d coat keeping one unified mesh instead of having to break the mesh into parts and redoing the uvs? How can i go about doing that? Is that possible? Thank you
  20. Hello there! been using 3dCoat for a while now and something I havent been able to figure out yet is if there is a way to sort of drag select over a bunch of islands that are stacked so I can move and scale them all at the same time. They are all stacked ontop of each other to help with the texture resolution since it is just a bunch of planks of wood that dont really need dedicated space on the uv map. http://prntscr.com/lrbw9j Thanks!

    Cinema 4d to 3D Coat

    Hello, just a quick question. is it possible to maintain my selection tags and material assignments from Cinema4d to 3D Coat and back? I had assigned materials and after i did my UVs in 3d Coat and exported my fbx back to Cinema4D all that was gone replaced with a single generic material. No selection tags, no materials? Could this be because of an export setting or is the fbx file format? i dont know. Thanks
  22. 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
  24. 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?
  25. 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
