Meshlab vs meshmixer software#
If you have a Windows machine, you can try using the professional software Netfabb to repair this model. Alas, although MeshLab can identify these problems, it’s not able to actually fix them usual MeshLab repair menu options such as “Remove Faces from Nonmanifold Edges” and “Remove T-Vertices by Edge Flip” are unsuccessful here. When we added those new triangles, we created some bad geometry where the pairs of coincident faces meet. The problem lies with where the new faces intersect. However, when we try to open our broken file in MeshLab we get this error:Īfter opening the file and looking through some of the Cleaning & Repairing filters, we see that there are some non-manifold faces:
It’s more complicated than Meshmixer, but can often take care of bad geometry like reversed normals and non-manifold faces. Although Meshmixer knows something is wrong here, its Inspector cannot repair it:Īnother great mesh-manipulation tool is MeshLab for a primer on making simple mesh fixes with MeshLab, check out our previous article Tutorial Tuesday 5: Quick Fixes With MeshLab. But, in this case, when we open our broken file in Meshmixer to see what’s going wrong, the faces don’t load in.
Meshmixer is a great first tool for modifying 3D meshes for an in-depth example see our previous article Tutorial Tuesday 50: Using Meshmixer to Make 3D Models Thick Enough to 3D Print. Nice! But when we try to upload to Shapeways, we get this error message: The screenshot below shows what it looked like when I did this in TopMod I added the closed triangle faces, and everything seems fine: We’re going to turn this into a tealight ring and add some solid faces to the wireframe to create a partially-enclosed look. So that we can follow exactly what’s going wrong, we’ll create a bad mesh by modifying an existing 3D model, my Deltoidal Hexecontahedron Catalan Bracelet: I will need to use a STANDARD shader for it to work.What do you do when your 3D model is broken? I mean really broken, like “can’t even upload it” broken, or “half of my triangles are disappearing” broken? In this post we’ll talk about what to do when your usual mesh-repairing strategies fail and you need to bring out the big guns. If I stored vertex color in the color channel of a VRay or Mental Ray Shader, it probably will not export that color information correctly. It would be the same in 3ds Max.I'm pretty sure. I'm thinking maybe you have a special shader on the model in your original app and it's not storing the color on export. He said it uses 16bit rather than OBJ's 8bit. I don't work with PLY files, but Andrew did say that it was preferable to use PLY format for importing a file with Vertex Color. But if it's relatively Dense, then the color representation should be dramatically better. This means that if the obj model has a relatively low poly count, there are too few vertices to get an accurate baking result. I know that if you have a UV mapped model with texture maps assigned to it > export as an obj file.if those associated texture map files are in the same directory as the obj file itself (should be placed there, by default).when you import into the Voxel Room, you should see the color from those files baked into the vertices. If it does not have any color, then naturally something didn't work when you initially exported the file. If it does indeed have color, then there is something wrong on 3D Coat's end.
Start with a fresh scene and import the file. I would first inspect the file you export in the very same app that you used to create the model you are sending to 3D Coat. Everything with color shows up fine for me in both Meshmixer and Meshlab. So I tried your suggestion and converted to a color obj file an still no luck.
