Project using Overlay Image

I've just been experimenting with the Overlay Image effect. I haven't used this effect before so it took a fair bit of trial and error to get the building into the right position. This image is a straight from Lumion without any post-processing.

Really cool Derek. Shadows integrate perfectly and that small patch of a Lacebark Elm in the upper left corner makes it all come together nicely. Well done m8!

Excellent.

I've been wanting to try this but haven't had the right circumstance pop up. This makes me want to just give it a whirl and try to incorporate wherever possible.

How long would you say it took to monkey around to get it just right?

Did you find the controls to be intuitive or a bit difficult?

And to think I've limited myself to using the image overlay effect only for watermarking our company logo...   |:( |:( |:(

Thanks for all your comments. Much appreciated! The thing to remember about 'Overlay Image' is that the image will take precedence over your model. So what you first need to do is remove all parts of your photo that correspond with where you expect your model will sit. (Save as a .PNG with transparent background). You'll probably want to remove the sky from your photo so that you can use the Lumion sky. Also, try to use an image with as few foreground objects as possible. Keep your original photo just in case you need to add elements of the original environment back into the scene. The whole process is done using movie effects. Pan and zoom until your model sits just in the right spot then capture the position. Don't forget you can use the arrows on your keyboard to do this. Adjust sun angles etc. to match shadows in the scene . Another important thing to remember is that because most of us use a wide screen monitor the 'overlay image' may look 'stretched' and you may need to squash your model slightly to compensate, then correct the image ratio later. I worked most of this out through trial and error myself, but there may be a better way to complete some of these steps. Anyway, I hope this helps.

I'd say just format/crop your photo as needed to make it widescreen format.  I did that with my company logo....I just created a png file that was a decent resolution at 16x9 ratio most of the image is completely transparent.  I can then place my logo anywhere in that image file and then when I do the image overlay I just simply load in the 16x9 ratio transparent png and presto.  No fuss...no mess.  It works great when I want to add additional company logos...text...etc.  I know that where I place them in the png is where they will be on the final exported Lumion image.  See attached image...  My original is psd format so then I can add particular items to their own layer to turn on or off before I save the particular png file.

Thanks for all your comments! For anyone interested, I actually used a blue metal material for the windows. It seemed to reflect better than glass in this scene.
