Import .OBJ model with png maps

leahalbert11

Hello, my artist is MIA and I need a couple of hirh resolution stills of my model. Have attached a screengrab of my folder contents, just need to know how to get the .png files in Maps onto the model after importing the .obj. I think it was built in ZBrush but may also have been exported from Unity as he supplied Unity screenshots.

Unfortunately it is unlikely to be enough simply to import the maps, but I can at least guide you through that.

Import the OBJ (or FBX as desired) - File>Import, I would try the modo preset in the OBJ import options dialogue to set the scaling

Open the Surfaces pane (Window>Panse(Tabs)>Surfaces). In the Tools menu select the Surface Selection Tool.

Hover the mouse over the model - does the whole thing highlight? If so just click on it. If not you are going to have to go to the Editor tab in the Surfaces pane and click on the model's name to select all its surface groups

In the Surfaces pane it should eb showing the Presets tab - from the list at the left go to Shaders>Iray and in the panel showing icons double-click !Iray Uber base.

Click on the Editor tab in the Surfaces pane.

At the top of the parameter list make sure Base Mixing is set to PBR Specular/Glossiness (this is the simplest listing, though it may not be the ebst choice).

Click the triamgle button under base Colour and then from the menu pick browse... and select the Character_Albedo map

Click the triangle under Normal map, Browse..., and pick Character_NM.

Character_AO is ambient occlusion - it doesn't have a lost it must go to but it could be used in various spots - for example it could control Glossiness (less occluded areas would be more prone to rubbing and so would be smoother than the areas ticked out of the way).

None of that will help with picking colours/strengths for other properties, however.

Glad to have helped, I wasn't sure how useful that would be.
