Saving Spot Render

bradassociates

I've searched the discussion forum and YouTube tutorial videos, but couldn't find good instructions.

Sometimes when I render, there is one item in the render that is off or incorrect.  I don't want to spend the time having to re-render for that one element.   Is it possible to readjust the scene to correct the item, then use the spot render application on that one item such that only that portion can be saved?  The question here is about saving the smaller spot render as, say, a .jpg.  Then it could then be used in Photoshop or whatever other graphics editor one uses very quickly to fix the original larger render without the time required for a complete re-render.

If you set the Spot render to go to a New Window, via the Tool settings pane, it will be the right size for compositing and will have the usual save button. Save it in Tiff or PNG format and it will also be masked for compositing.

Yes it is. Make sure the view is the same as your original render, and pick the spot render tool. Open the "Tool Options" tab, and tell it to render to a new window. Select the area to render with the tool, and it'll render an image as big as your original render, but all transparent apart from the bit you selected. It's then easy to combine the two in Photoshop.

The only thing to look out for is if you rendered through a camera with local dimensions set. These are ignored by the spot render tool, even if you're looking through that camera at the time. In that case, you need to change the global dimensions to match the local ones before doing the spot render.

Thank you for the instruction.   I've figured it out.  For those like me new to Daz, the "tool settings" feature is not clearly marked.  It is the unnamed upward arrow feature adjacent to the spot render icon.

Also, save as .png as Richard says above.   The easiest way to bring it into the original fully rendered image, if using Photoshop, is to use the "Place" feature.  Open the original render and look under File => Place open up the new spot render .png.   The .png will have masked the image to where only the new image shows and the rest is invisible.  Because the image is the same size as the original, it will align correctly into the original render without the need to move/adjust - a caveat is the matter about dimensions chris indicates above.   However, I had no problem - it works great.
