Thanks for the input so far guys. Worked all dang morning on this. Here's some follow-up:
* The image is 660Kb. The Radeon 9500 can handle anything I throw at it...
* The Material renders just fine, it's just the 3D window (OpenGL) - remember this is pre Lightworks 8.1
* a different material on the affected surfaces work just fine. A new wall object with the material in question will black out,
* I tried all the texture suggestions: new material using the texture in question and same material using a different texture - it is the texture image that seems to be the culprit, so
* I opened the .jpg, no alpha channel or anything else odd in there, so I saved it as TIFF and as a new jpg. Then reattached these new texture files to the Material - and both do the same dang blackout thing.
Below is the 3D window not blacked out. I really have to use this Eldorado Stone Shadow Rock material - it is client spec'd.
One off subject question opened by "Link". Is there any T&T's or tutorials out there on using SEO for roofs? I've never been able to get it to work, so still use roof joins and trim to roof for all my roof planes. None of the GS Tutorial or User Guides cover it, and neither did the the great Aussie Virtual Tutor 8.
