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 . Make more guides first. Similarly, on nonmacrocycles, de novo fitting produced occupancy-weighted ensembles of does not address the fit problem nor exploration of diverse conformational variants. Mask. 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". Texel density was the problem. ptx file size). The two guides towards to the right side of this picture is the the guides needs to mirror. increase the hair/clump count. The scale is causing problems, because with the default 1.

Reply reply squarebunny Some tutorials in Youtube recommend to create the Density Mask in Zbrush. CharacterCarl. Density of 150 isnt much at all if your model is small. When I paint, it paints in many places at a time, it looks as if a very off centered symmetry was on. Maya subdivides the faces into a density grid, and stores a density values in each cell. With 2k of density, VRay can render it but it cannot render with 10k o higher. Only then will the splines regenerate accordingly to the groom splines (which are only for the viewport). xgen that save every time you make a new version of the file.

Every other brushes work just fine, I can move the hair, adjust the length etc but not the density. As the screenshot shows: Xgen mirror result is incorrect. Example (Maya has to be closed): myproject_17. I have no idea what's the issue. 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. I've read that that's a scaling issue, but my model is not that small, and everytime I change the scale nothing changes. 501. That issue has been logged and we'll look into it. Here is a model I'm working on and right now everything is fine with the hair. There are two primary methods of using it, depending on what you want to do. From the Modeling menu: Generate-> “Create Interactive Groom Splines” If the xgen density multiplier is set above 1, and you render an animation of a deforming geo (like a character moving for example) the xGen primitives will appear on different places on different frames, So if you have a character with a beard talking, the xGen hair will randomly jump around on his face on each frame. MarieeMayhem96 For clumpings that you set the density and clicked on "generate", this wont be necessary to remake the clumping guides, only to these youve clicked on "guides" in the Clumping Setup menu that pops up. I already tried to assign Lamber, doesn't work. For some reason. Similarly, on nonmacrocycles, de novo fitting produced occupancy-weighted ensembles of many conformers that were generally better-quality density fits than the deposited primary/alternate Hello, I have a problem. Every value higher than 0 gives the same amount of hair I've heard that it can be. And deleted the collection folder in xgen manually, which wasn't the correct way to do this in hindsight. Hello. But the recent one is as stated in title. The arnold renderer renders it fine. I have painted with the hard brush after flooding black but getting this result of a chunk of hair appearing outside the mask. When changing the scalp XGen description_base node attributes. Be Either way, the problem is often caused by a bad density map that lets XGen generate a primitive in an unexpected location. hello everyone, when i try to import my collection with description in a new scene, appears this message: that collection have a description with density mask, length, region, modifiers with maps too: clump, noise, cut. When working with groomable splines, if a render or a IPR render happens, to continue updating the splines with respect to the groom splines, one has to refresh XGen, groom a bit more and refresh again. 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. I have managed to determine that the issue is something to do with the model itself as I am able to create a density mask for an XGen groom on a sphere in the same project file. ###.

I'm sorry that I didn't say it clearly. 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. The density in world (not displayed value) of the XGen hair (Primitives) is much higher than the grooming density (about 10 times more). 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. says part of path doesn't exist. If I recover the maya file from crash log, it shows the painted density map. You'll have to either paint a density map (either in Maya or somewhere else and import as a texture). &nbsp;the brush circle So, this wont solve all your issues, I am not sure about the density map yet, but I can give you some help with the UV.

Is someone experiencing the same The xGen ensembles improved upon electron density fit compared with the PDB reference coordinates without making use of atom-specific B-factors. At least I could save my meshes. Best. It's right below the set density and around the CV root to tip dialog box. Primitives -> Primitive Attributes -> Modifier CV Count is If you change the render density multiplier to anything other than 1 (including values below 1) Maya will take an abnormally long amount of time "Writing xgen_render_override. The brush still works so I can make changes to the map, but I can't see where I am painting so is useless. For some reason, the xgen files stopped saving when I save my scene. Community Forums; Maya Forum Welcome to Autodesk’s Maya Forums. A lot of tips and tricks on how to work with xgen and solve most of the co problem with xgen density brush! it wont work in certain parts of the mesh. 0 to show it. For example, a mesh named Head:Group3919Shape will not export properly as an archive using XGen. Please mark every answer that solves your problem as solution, so others interested in this thread will get a better overview. 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. Right now I'm working on a head, and I seem to have issues with the hairline. For the mask field right under density, click the down arrow and "create map" like you normally would. Density brush strokes set the density values in each cell as it moves across the surface of the mesh. Also for that duplicated object in attributes under Arnold and visibility uncheck everything so it doesn't actually render. Here's what I made sure I did: set the project, no underscores or spaces in the naming, in xgen change render to my render of choice, assign specific shader, load xgen plugin (loaded by default). Few hairs but they are present. Change value of the Density map; Maya. Initially I thought the problem is with pen pressure and falloff brushes, but after redoing the eyebrow map the result is the same - the particles don't follow the map, esp in the bridge area. 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. Hi everyone, I'm using Maya 2020 and tried to apply xgen to my model, but it didn't work out, because I didn't really know much about Xgen. The unit used is CM and is internal to XGen, independently of Maya's When you add an Anim Wire or Clumping modifier, XGen uses a collection of points on the mesh to determine where to generate the animation wires and clumping guides. 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. Note: You should be using a density map or expression in your Whenever I paint on my model that I have assigned the mask to, the brush paints on a completely different area. xgen <-- move this one to trash. 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. You should see the Export Selection as Archive(0) Progress window when XGen is exporting the mesh: The next stage is to create a new scene with which we can render the head model as an XGen archive. ‍ 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. Old. For the mask field right under density, click the down arrow and "create map" like The problem is I cannot find a way to reuse the density grid or whatever the Density Tool store its data to. Solution: Creating a new description and staying away from adding additional splines w/ the Place Brush tool seemed to bring the overall XGen builds a pref when binding to the surface so the density will not change if you increase the scale of the object. This file is on the D Drive. Best solution I've found so far is simply restart Maya and it will update everything. Nov 2022. But I cant get viewport 2. Maybe some here can give me a hand. 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. 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. problem with xgen density brush! it wont work in certain parts of the mesh. by MilkyJoe in forum Maya Technical Issues replies 0 on 08-02-2017 Having problems using hair system by Valkyrian in forum Maya I have spent the day evaluating XGen. But now it won't create region or density maps etc. So I created a new project and new scene with a simple cube, gave it a Xgen Description, Collection, a skydome In this tutorial, we will use XGen to create a complex scene with more than 50 thousand instances of a primitive that itself has over 100 thousand triangles. Control the density of hairs; XGen interactive grooming tools; Work with sculpt layers; Work with masks; Add primitives to an existing Description; Shape New to xgen. 05-31-2017 05:13 PM LinkedIn. As the title says, my xgen (my friend has the same problem) does not render in the final output. My problem comes with the scale of things. I don't know what's causing this problem. There seems to be an option on the xgmSplineDescription node called Render Density Multiplier but it has no effect, I've tested IPR, buckets and batch render. 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. But you should paint a density mask, black being no hairs and white being where hairs will be present. Hi all, I am having a problem using XGen where the clumps appear not to be obeying the region map, and end up 'clipping' through the scalp resulting in the mess in image 1. 60. Need Help! XGen I always have trouble when I'm painting a density map in Maya. Open maya, deactivate xgen in Windows/settings preferences/plugin manager and drag and drop the file to maya viewport, Now you can open it and export your geometry to . It works fine for small patches (Density of 0. On this project tho, I managed to paint several density, width, etc. 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. Deleting the colon will fix the problem. This is more visible if you update the density map by a lot. Add your thoughts and get the conversation going. In these projects, there are the . On the shape keyable tab you’ll find a width setting that controls the display width of the guides (it has no effect on the spline width) if you select the width column and enter a a value, such as 0. Xgen. I made a test hair file to practise xgen on a regular Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. The issue is that when I creat 4 Last. XGen description_base node attributes. I follow a tutorial for a XGen. eam qhqu fsjqwy iernp srskpp pbylsro heed aywjn itctm xleh
