Re: Importing OBJ file in Sweethome3D Be aware that downloaded objects from sites like Archive3D and CGTrader are often a little 'broken' with parts not correctly lined up or unmapped textures. This is especially true for the free objects. Try either a 3DS or FBX version since those often offer better results than an OBJ+NTL file. On CGTrader the FBX versions are generally the best (in my experience) but you have to use a program like Blender to import them and export them to a 3DS file which can be imported by SH3D. It's an option if the original 3DS or OBJ versions fail. You have a better chance of correctly mapped textures with a FBX or 3DS file. Blender is also useful to realign a wrong part of an object. A tip while importing objects from third party sites: many times the size seems wrong in SH3D because the scale is different. Check the number and in most cases moving the decimal point one or two places to the left will give you the correct dimensions. Even if textures are not mapped you can (re-)create an otherwise good object by manually mapping the textures using the Color and Texture Modify button in SH3D. Of course this requires that the different parts are correctly listed in the object file. If you encounter just a single item to map you are out of luck because there are no parts to map. Most of the Archive3D files can be imported without a problem but the rar files sometimes show 0 files (some are very old). Specifically on Linux I found that some rar files from Archive3D can only be extracted with p7zip (a Linux port of 7zip). SH3D expects a zip file so the rar file must be extracted anyway. It is advisable to copy textures that are in a subdirectory to the directory where the OBJ/MTL or 3DS file is. This often avoids the need to manually map the textures in SH3D. ---------------------------------------- Dodecagon.nl 1300+ 3D models, manuals, and projects |
