- Do you still have Adobe Photoshop CS4 Extended on your computer? If so, then make sure you don't have the plug-ins installed in the CS4 Plug-ins folder - you only want to have them in PS CS5 Extended's Plug-ins folder.
- With the Design 3D CX plug-ins set up in PS CS5 Extended, open Photoshop CS5 and create a new empty document. Go to Filters > Strata Design 3D CX > Model New.
This will open Design 3D CX and transfer some data. In Design 3D CX, place an object in the scene and apply a texture, then click the "Send Model to Photoshop" button in the button bar or select the command in the File menu. This will send the object back to Photoshop.
This process helps establish the connection between PS CS5 and Design 3D CX.
- You may also need to shut down Design 3D CX and Photoshop, and then restart your machine.
