Hiro77777 Posted February 19 Share Posted February 19 After we change to node-file, we change material parameter and it's possible to change color of surface. we don't have original unigine files, but we want to change clothes color etc.(e.g. this is hair color.) so could you let me know material numbers mean? Example <surface name="hair_lod_0" intersection="1" max_visible_distance="15" physics_friction="1" physics_restitution="1" material="363f1fca3f080ca1e098bd8c02625b7b7ae39a9e"/> when I changed "363f1fca3f080ca1e098bd8c02625b7b7ae39a9e", it's possible to change color, but I'm not sure thi format.

arizmenda Posted February 20 Share Posted February 20 Hi Hiro77777, If you open .node file via text editors (e.g. WordPad or Notepad), you'll see information about the parameters this node has. In your case: surface name intersection max_visible_distance physics_friction physics_restitution material But it could be much more, based on the complexity of an object and number of parameters you have. Tooltips in the editor will help you with description of any parameter. If we talk about material="363f1fca3f080ca1e098bd8c02625b7b7ae39a9e" line - this is the link to material guid number. The information about the material with this guid is stored in another file .mat. (GUID is unique id of any asset. You can read more here) It looks like this: If you want to change the color of material via text editor, you should look for albedo_color parameter. But it will be much more simple to do it in Unigine Editor. We don't recommend to change the guid numbers at any case, it can cause the corruption of your nodes, meshes, materials etc. We also would like to know the current version of your SDK to check if our recommendations were correct , because the SDK is constantly changing and improving.

Hiro77777 Posted February 20 Author Share Posted February 20 Hello arizmenda-san, thank you for your support. I hope to modify color etc. on Unigine Editor, but Main software maker has original files, and we don't have original data of Unigine. I'm not sure correct ver., but I often use SDK 2.16.0.1 or 2.15.1. Thanks. arizmendaz Link to comment
arizmenda Posted February 21 Share Posted February 21 Hi Hiro77777, I see! As I said, you can try to change color in the text editor. You need this line in .mat file: <parameter name="albedo_color" expression="0">0 1 0.0313725509 1</parameter>. Each of 3 numbers is a color channel - red, green and blue. 0 is minimum value, 1 is maximum value. And it corresponds to 0 to 255 in basic color coding. In the line above albedo_color has 0 1 ~0 as value, it means 0; 255; 0 - green color. You can use RGB color palettes to make your job easier. Thanks! Link to comment
Hiro77777 Posted February 21 Author Share Posted February 21 Hi arizmenda-san, When I make node file, I found .mat-files. but I don't find .mat-file in software tool package. I guess .mat files are hidden. there are .node and node.meta files. if this is situation, is it difficult to change color from .node or node.meta file? Thanks. Link to comment
arizmenda Posted February 21 Share Posted February 21 Hello Hiro77777, Unfortunately, there is no way to change the color in a .node or .meta file. You need to have access to .mat files to change material parameters in text editors. Thanks! Link to comment
