If anyone's interested, this is how I personalize MAT thumbnails. 1. Render the image you want in the MAT. I render at 500x500. In this case it's a 'MAT' or 'SET' file which switches body parts (drawers in a cupboard) on/off. So I make 2 renders, one at 100% transparency and one at 50% transparency. This distinguishes on from off. 2. Import the render to a paint program and add your logo. Save it under a new name as a jpeg. It's a good idea to keep a file with the various logos in layers, so you just drag them into the render. 3. In Poser, go to Menu/File/Import/Background Picture (alt-f-i-b) and import the jpeg with your logo. 4. Move the camera to one side so your figure/object is out of frame, leaving just the background pic. 5. Now either save the MAT to a library, then edit the file to make a proper MAT. Or, if you make the MATs in MatPoseEdit or whatever, just save it to any library, rename the .rsr to match your MAT file, then delete the .pz2/.cm2/whatever. I'm sure there are plenty other ways to do this. The main point is to create an image with an accompanying logo or text which tells people what the damned thing is. I use semi-transparency to indicate an 'off' state. You can see what the body parts are, but know they're off. You could use gray instead if it's for a texture on/off. With maybe TEX/NO-TEX as an added indicator. Hope this helps. Hope people actually start doing it. LOL. mac
