Iray Preview Going Black With Empty Scene

Devon Oreschnick

Hi! I had my Iray preview and renders go entirely black on me like there wasn't enough memory in my GPU for the scene right in the middle of a project. The problem is that this happens regardless of how empty the scene is and it only happens with the stable public build. I've tried restarting my PC, updating the version I'm working on, even uninstalling and reinstalling. The good news is that the publisher's build I'm using works totally fine. However, I'd really like to have the public build back up and running. Please keejp in mind that this happened in the middle of a working project. Render settings were not changed. The only thing that was altered was that I loaded an object. The scene is NOT the problem because it persists with a blank scene (see attachment).

Okay. The jpeg won't upload, so just picture a black screen where my Iray preview should be and a default scene.

very odd. If this happened in the middle of a scene for no reason, it could be hardware or driver related and not DS related.

I've even gone and updated my graphics cards. Still no change. I'd worry that it was a hardware thing, except it's working fine on the publisher's build. It couldn't be the graphics cards.

It's not your computer, it's the item you loaded in the scene, some will do that, something to do with lights I think, I might be wrong, so you have to have a certain setting to fix it. I know others have had the problems and asked about it here on the forums, so you could previous posts (shouldn't take long) till you see a title about a black screen.

I would tell you but I just can't seem to remember what you need to do.

I figured it out. My God, I'm stupid.
