Software platforms write to OBJ files in different ways, so you may need to take different steps or experience varying performance when exporting from third party software. In some cases, you may find that loading your OBJ file into software that Prospect is natively integrated with, such as Rhino, and then launching through our add-in will produce superior results and allow you to better maintain the fidelity of your OBJ file.
Follow these steps in order to successfully produce an OBJ and MTL file that works with IrisVR Prospect with 3DS Max.
1. Before exporting, create a new folder on your computer where you will save the OBJ and texture files. Open Asset Tracking in 3DS Max.
2. Select all of the Full Paths under Maps / Shaders and right click to open a Menu
3. Select 'Make Path Relative to Project Folder'
4. Exit out of Asset Tracking
5. Select Export
4. Select OBJ in the dropdown and name your file
5. Make sure the options look like below
(Important Update) In prospect beta version 3.8, we assumed right-handed coordinate system with the Y axis as the Up axis, but, in the latest release, we have switched to the Z axis as the Up axis. This means that files exported using the previous settings for the Z axis will appear rotated. Exporting the file again, using the settings below will solve this problem.
6. Select Map-Export and make sure 'Use map-path' is unchecked.
7. Maintain the format as JPG
8. Select Export. The resulting folder should look something like this, with the various textures used in your file visible as images:
9. Drag and Drop your file into Prospect and launch!
You may experience incompatibility when using the layers function with an OBJ file, in which case we recommend using a native file format.
