If i plug the bg (or any image) into the image input of the volumeFog, the vF turns red and the console reports that it failed. Anyone know why that's happening? I'm sure it's something obvious i'm overlooking.

}

also, if i enable open cl it crashes fusion. Not sure how to troubleshoot that if anyone has any tips.

In your volume fog, you need to set your "First slice time" to 1 or more. it's set to 0.
Try that and see if that helps!

The hint is in the error: it says it failed at time "*". The way the volume fog works is it takes an image at a certain point in time, then uses a slice for each moment in time after that. If you plug in a fast noise and set the seethe rate pretty high, you'll see that your fog becomes really interesting. The fog tool is pretty awesome..have fun! (also, you don't need high image resolution for the input image...256 or 512 gives good results)

that was it! completely overlooked that setting.

thank you very much(:

this is very helpful. And it really is awesome - so much faster than fluids or participating media but it can be just as effective for many things.

thanks!
