PhotoRendered picture in the right place of a photo backgr.?

[Anonymous]

How do I insert a PhotoRendered picture into a photographed background? Or how do I PhotoRender a picture into the exact spot of a background photo. Whit the right perspective in both of the pictures? I have this large building which i want to place into its real environment. How do I do that?

Use the picture tool to insert the background picture on your plan. Its a good idea to place some hotspots over the picture to refer to at points of reference eg. bottom and top corner of known walls (x2). Select the picture, go to Image / Align view. Follow the prompts first picking a point on your plan (at wall intersection) then on the two points in the photo (base of wall, top of wall), then the second point on the plan followed by the last 2 points on the photo. A dialogue box appears, put in the relevant heights, and a camera should be placed on your plan. Select the camera then go to 3D view. Then curse as it didn't work properly. Does that make sense?

Thanks for prompt reply it was comforting to know that others have sesarchedc for similar assistance. however I still came up with the same results.......see the attached jpg picture.

Any ideas now ?

Align View tool flaws aside, there is no substitute for slowly walking the model into place in a 3D OpenGL view.

Even Graphisoft's documentation says "Salt to taste."

As for merging a model with a background, Lightworks has the shadowcatcher shader. See:

In the book. [No surprise.]
