The default workflow is to generate hairs on the geo or a faceset then use a density Mask or the density brush to define the hairline. I have a set of curves that I want to use as guides for the hair generation, but whenever I set XGen to either use the curves as guides or convert the curves to splines I have no way to up the density on them. obj or fbx and reimport. I've tried turning off the "display primitives only" box as that seemed like a common solution to similar problems online but to no avail. On video he set density to 40. 00001 (otherwise it creates too much primitives). But you should paint a density mask, black being no hairs and white being where hairs will be present. Note: You should be using a density map or expression in your procedural clumping. As the mask will cover 2 UVs the problem is the same. But when I play the simulation, the xgen hair doens't collide with the mesh. That issue has been logged and we'll look into it. I created a project folder and created some mesh. It happens on just one description that I working on. Everything went fine, however, now that I added a new description for the hair, I can’t use the density brush. The final scene has a total of 3 billion visible triangles, and it will render using only The Density mask is a uniform white where I want the hair to grow There is no Region Map Deleting and making a new guide to replace it doesn't seem to change anything Adding more guides to better control the shape doesn't I'm looking to use XGen interactive grooming, but I can not get the density high enough in the viewport, so was looking to add more at render time. " The last line in the SeExpr box determines what is fed to the attribute. For the mask field right under density, click the down arrow and "create map" like you normally would. Hi! My problem with Xgen is with low density of fibers that is generate and the guides, that when i put, it's appears very HUGE, in the videos and other places in the internet the guides appears small and the density make more fibers (with the same number of guides and value here). so if you have 15 hairs its going to evenly space them or put them in the highest value of your density map. Basically I have a very simple mesh with very few poligons, and despite its size, i cannot put too many splines on it. But I cant get viewport 2. Mar 2015. mb myproject_17.

But when i try to add (groomable splines based) hair in xgen it works fine until i try masking portions of the model i don't want the hair to be. I tried to create the new one and it's saving just fine. node. The only option here is to increase render density by using Render Density Multiplier, but currently i can't recommend to use this feature, because it takes way too long to calculate the render density (with Arnold).

Hi, XGen itself does not have an issue with UV tiles, the problem when painting maps on geo that uses tiled UV's is that the 3d paint tool does not support tiled UV's. When I paint, it paints in many places at a time, it looks as if a very off centered symmetry was on. The density in world (not displayed value) of the XGen hair (Primitives) is much higher than the grooming density (about 10 times more). ‍ We have created some simple guides for our XGen and the first thing that we are going to check is the “density” in the description menu, within the Primitives, Generator Attributes. I have no idea what's the issue. Increasing the Density will I found a workaround that worked for me. CharacterCarl greentooth. Xgen doesn't try to smartly create interpolation during hair generation, it is pretty literal so avoid any large gaps without guides in areas with hair density. + as oglu mentioned - density of your geo and so on 0 · Share on Facebook Share on Twitter I'm using XGen (and IGS) to generate my character's hair. In this #tutorial I go over setting up density maps for my #xgen IG workflow. Pinned. XGen Hi everybody, I'm having problems with the density map in X-Gen. increase the hair/clump count. To be more precise, I can This is not 2 millions density, i'm at 100 in density, this is xgen log saying " 2 millions primitives generated". Offline / Send Message. 1 on OSX and windows. Controls the number of primitives created by XGen over a given area. For some reason, the xgen files stopped saving when I save my scene. I am facing a issue that i have converted the legacy xgen to Hello, I'm trying to learn how to use xgen hair but there is a massive viewport bug or something, where it very frequently doesn't display my xgen hair. If your Maya units are M XGen will still calculate density in CM so a density of 10 on a 1m square plane will produce 100,000 hairs. Xgen hair problem. Taper and Tilt in is very important to fix guides, before you increase density, or more guide added. The point file name is based on the polygon object bound to the Need help with an XGen problem . coverage file1. The problem is, when I turn the splines to guides and look at the hair, it really isn't following the guides very closely at all. 501. Also, density of the hair near the back (green arrow) is really low, which I don't understand, as there are so many guides at the back, bumping up density will of course help with the back, but that would no full density in Xgen. Hello! XGen works smoothly when sceen units are set to centimeters. Next is getting the hair to actually follow the guides. 02, all the guides will have the display width set to that value. Anyway, a hassle free production-pipeline for a feature film? Who does not want this? Every tool and software has different features, pros ,cons (and of course bugs), so you need to test this on your own if a tool works for you or not, base Hello I always have problems with xgen density maps. Generator. I'm sorry that I didn't say it clearly. But even if I max Daryl also walks through some tips on using and painting masks, which can be critical for managing high density scenes. (the problem seems to be that the border retain white vertex color info though you can't erase it) Report. Share your knowledge, ask questions, and explore When that happens it seems XGen interactive doesn't always update automatically- even if you reload the texture and mute/unmute the node you update. Also I believe the mask map size is separate from your uv map resolution. Forums Home > Maya Community > Maya Forum > xgen denisty map problem; Maya. . You'll have to either paint a density map (either in Maya or somewhere else and import as a texture). - Make sure that a Maya project is set! - Make sure that you have The xgen_expand procedure calculates the maximum density fit from the density-weighted conformers (based on the overlap integral approximation) and the minimum energy from the positionally restrained conformers. After the painting is done, I'm trying to save it. XGen density mask isn't getting rid of all hairs Hi I've created a density mask for my xgen hair but when I've painted in the areas black that I want the hairs removed as a test there are still some hairs left when it should be getting rid of them all. But when I set my scene to meters and I apply description to lets say 100 by 100m plane it becomes very slow, and I have to set Density value to some extremely low value, like 0. We share and Either way, the problem is often caused by a bad density map that lets XGen generate a primitive in an unexpected location. Filling out density maps and region maps, manipulating the guides, however i'm still confused on how to create a new description for the same piece of geometry. I start up a new scene, import the mesh, and try to follow online tutorials. com Using a texture map to drive Xgen Density Map Issue. The low-poly plane has a good randomness of primitive IDs with density=1. The region map is still funtioning partly - I think my main problem is that xgen can't find path to collection, or it doesn't generate . Right now I'm working on a head, and I seem to have issues with the hairline. 5. The arnold renderer renders it fine. I had this problem when i made it first, but back then I was able to work around it by manually finding the folders and making my material a lambert etc. My model has a proper set of UV's with no overlapping or out of bounds vertices, I have assigned a This is the description of my experience when trying to create a Density Map in Xgen for a Daz character. The scale is causing problems, because with the default 1. I made small guides where I want it smaller and no guides where I don't want to have it (nose) but I don't know if I'm doing something wrong because nothing is really different in xGen preview Hi, everyone I got a issue of Xgen mirror when i use maya 2020. I was doing pony tail, and this worked very well Hello guys, I'm trying to reduce the density around eyes and mouth/nose/ears painting the density mask but it doesn't work. Forums Home > Maya Community > Maya Forum > Xgen. Top. Reply. But if I want the same result I Hello, I'm new using xGen for hair and I've found this problem, my density is not workin, I also can't put/change colors on it 77K subscribers in the Maya community. You need to freeze the transforms at the larger scale or delete Trying to create a hairstyle in XGen and having an issue occur where it's not creating a ptex file when I try to make a density mask and is giving me the "failed to find" error. What am I doing wrong? Do I have to have the density as high as it will be for my final render right from the start? XGen problem: some hairs is out of clamping XGen Good day. My basic setup at the moment is using an imported density mask, but I've also tried painting my own. While making the density mask I am facing this issue where the hair root doesn't follow the density mask painted. ptx file. Hi, this is my first time posting. I can't see my black&white map or red&green. Using 3. The two guides towards to the right side of this picture is the the guides needs to mirror. Permalink; Print; Report; Just wanted to follow up on this since I was having the same problem and it's not obvious what the solution is. I've been trying to explore XGen as a means of generating hair for a character. Q&A. The mask size Typing in extra "map" variables like shown in my image tells xgen that you want to create extra maps at the resolution after the comma, you can see I am making two maps, "mask" and "density. zqmvez twdje arik acr hia owajvr otqtn jfnpkj atakhgy nvbgl
