Luckily I know more about PTGui than TG
Firstly, it looks like you're trying to get PTGui to align the images for you. The beauty with using CG renders is that you know what all of the numbers are. PTGui opens up in a simple mode by default, hiding the things you need. You want the Advanced mode.
[attach=1]
This opens up a lot of new panels of which you need only 4
Lens settings:Set horizontal fov of the renders, lens type rectilinear (default)
Panorama settings:Set the projection type. fov's aren't really required, there's an easier way to set those.
Image parameters:This is the key one, where you set the camera positions for each of the renders
Create panorama:Your output options.
A few notes of use:
PTGui has live links to the files. Change a render while PTGui is open and the image will change in PTGui.
You can combine images with different horizontal fovs, by ticking the boxes in the lens column under "Use individual parameters for:" on the Lens settings tab. On the Image parameters tab you can then enter the fov for each of the images you ticked.
An easy way to set the dimensions of the output of the stitched result is to use the panorama editor (Tools > Panorama editor) and tell it to fit the output to the images (Edit > Fit panorama)
You can also crop the output image in the panorama editor by dragging from the edge of the image.
And now for the biggy... You are going to end up with a VERY big image(s) and it will be impractical to try and do all of this in PTGui. For your final renders I'd recommend something like this:
- Load images (you don't need to do them all at once)
- Lens settings: set fov of renders
- Image parameters: skip this!
- Panorama settings: Choose projection
- Panorama editor: Fit panorama and crop image vertically as required
e.g. [attach=2] - Create Panorama: Width = width of input images, Layers = Individual layers only
This will give you separate images of each render that can simply be butted up against each other in Photoshop. Attached a PTGui project file illustrating this. (just rename it to ".pts")
Once you have a project file set up I'd recommend saving it as a template (File > Save as Template). This makes it easy to re-use the settings. You just have to load some images and then File > Apply template.
Having a play with your TGD. The camera tilt is -3, I'll give you a demo of why it's better to use 0 and crop.
