Multple photomatch
-
Can anyone explain how to photomatch the same building multiple times?
I want to rough-out the shape of the building from an overall photomatch but then rotate to different views and even zoom in to model detail work with subsequent p.m.'ing.
I'm not sure if this is even possible. Does anyone have any experience with this? -
Doing photomatch with multiple source photos can be confusing. Here is a good workflow.
- Bring in your first photos and do the photo match calibration.
- Draw some basic massing
- Now, before you bring in your second photo move your axis location (the tool with the red blue and green arrow) to a corner of your building that will be visible in the photo you are about to bring in.
- Then import the second photo and calibrate.
- Repeat this process (move origin then import and calibrate photo) for any additional photos.
If you loop around your building and your last photo doesn't match well with the first then you may have to make some adjustments to earlier calibrations. I would keep massing simple until all of the photos are in to your satisfaction. Then model the detail.
Hope this helps. I think I had old tutorial in the old SU forum, I'll see if I can find it on a quick search.

I haven't had a chance to try it out yet, but that sounds really helpful. Thanks for the advice. Any good tips on setting the scale of the photo?

You can set the grid scale when you are setting up or editing your photo match. First get the perspective lines up, and then you can move the mouse to the blue axis. The cursor should turn into an up/down arrow, clicking and dragging will change the scale. You need to know the true dimension of something in your photo. Full building height or width is best, but if you have to you can use a smaller object such as a door or window. If your object is too small then any minor flaw in your scaling will make things worse. That is why a large object is best.
You can also re-scale the model outside of MatchPhoto by using the measure tool on an object and then typing what you want it to be. You should get a warning "do you want to re-scale your entire model".
