![]() ![]() into one file) suitable for simulating detail on a low-poly copy of that original model. Specular maps are as necessary with Physically Based Materials for most cases. The primary purpose of this utility is to create (from a high-poly model with multiple detailed maps) a normal-map (a single bitmap produced by combining textures, bumps, ambient occlusion, etc. Its better back texture with zbrush or mud box ?or max will do that just fine ? i will work with archiviz so i will not use organic obj.įor your other concerns, You will need to bake normals in Max or other programs like xNormal. Yes sometimes i will want the texture on object follow different directions, so i think i need back right ? if i want back the texture i also need bake the normals ? i realy need specular map also ? When you import your model into UE4 and place the model in the scene when you hit the “Build” button in the tool bar to build lighting the second UV you’ve created will be used to “bake” the lighting information from the scene to create your shadows textures for the mesh. The second UV for lightmaps only needs to be set up so that you have adequate spacing between the UV islands, make sure everything is in the 0,1 space, and that there are no overlapping faces. The first UV for your textures (Diffuse, Normal, etc) is created and you can manipulate and apply textures how you see fit for your needs. In Max (or any modeling software) you will need to set up your UV channels accordingly. If you don't have Cheetah3D, you can download a trial version, which should be enough for Unity to do the conversion on import.I wanted to clarify “baking” in reference to UE4 with your second UV that is for Lightmaps. That is, a particular version of Unity can work or fail, depending on the machine it's running on. However on a Mac with an older system, I was able to update the projects to 2018 perfectly, then open them up in 2018 on my machine. On my machine, 2018 had LOTS of problems importing the older files. ![]() So, right-click on the teapot, Convert and Convert to edit poly (Fig.05). What we need to do now is to join both elements into a single object, without losing their materials. I had a related problem a while back when updating some projects from 2017 to 2018. Before starting, 3ds Max uses channels at the time to make UV Maps default textures are always set in Channel 1. I've been using Cheetah3D to make Unity models almost as long as Cheetah's been around, and this is something new starting with Unity 2020. And that it depends on both the version of Unity (2020 or later) and the version of macOS (in my case, 10.14). I think what it boils down to is that Cheetah exports an FBX format (don't know the FBX version) that Unity may or may not be able to import correctly. I've been trying a LOT of things (no success), and getting some suggestions on the Cheetah3D forum. Any suggestions?Īttached is a zip with the cube and texture (just a random PNG file and a Cheetah3D cube). My previous solution, updating from a different a version, is not an option this time. Same thing with FBX format, which makes me think this is a Unity issue, not Cheetah. I've recreated the model, and reimported many times with various settings. I've since updated the project to 2021.1.10, and the problems are still there. This project was created new in 2020.3.11. I had a similar problem a while back with textures rendering as solid colors in 2020.3.11:īut that occurred when updating a project from a previous Unity version. When I set the material's texture in the Inspector, it renders as a solid color. ![]() The imported material is missing its texture, same for Legacy External and Embedded material settings. ![]() You can also import assets from Maya for more detailed geometry. Mudbox gives you access to brush-based workflows for textures and polygons. Even more, the tool lets you make ambient, displacement, and normal occlusion maps. The cup tutorial is a good idea it contains a variety of tools. You can create meshes from sculpted, imported, or scanned data. There are two problems - this simple model, a cube with one material, (1) does not import correctly nor (2) does it render correctly. The baking texture tutorial is very well-written. This has always worked for me in the past. I created a new project in 2020.3.11 and imported a model in Cheetah 3D 7.5.1 (.jas) format. ![]()
