I stich these 4 pictures with blender enblend and built-in.
With enblend stitching takes much longer time.
With enblend blended picture was 176 MB and with built-in it was 222 MB.
Enblend did long time polishing built-in not .
Edit: Writing mistakes corrected
You mean enblend. 
I did it and work very well
In some days share my 360 DIY
I think @Morgan_Hardwood is right. @yteaot can we expand this into a post on the main site as a tutorial? Do you want to flesh it out just a little bit with me?
Alright. How to proceed?
I had a go at @troodon’s method, and it worked swimmingly: View Camera Still-Life Panorama | This is my first serious-i… | Flickr
Just ignore the horrific posterization in the web-viewer image Flickr generated, all of the download sizes look better 
In this one I used 15 exposures to get an effective sensor size of about 3.2x3.5 inches, although I cropped in quite a bit for the final edit (cropped from ~200MP to ~100, which still makes GIMP choke). I could have covered the whole space with just nine, but using the digital back on a view camera seems to generate some pretty pronounced centerfold artifacts in the shadows, and with some duplicate pixels in the in-between spaces enblend seems to do a pretty good job of smoothing them out. I just have to accept that it’s gonna take some time to process one of these monsters
I stumble upon a new software (for me) at work for stitching (and specifically, flat stitching). 
It’s called ImageJ. I play little around with it (the Fiji flavour, which contain stitching plugin). I found the Pairwise Stitching very effective, but as the name imply you can only do it by pair so if the collection contain a lot of image it tend to be click intensive.
There is another plugin Grid/Collection stitching, which seem very close to what @bieber was looking for. You can feed the plugin with image in a dedicated folder and choose from the various way of ordering them to help the plugin do the stitching. I have to admit that I didn’t succeed to make it work with the provided files, but I didn’t spent much time on it either. 
Hope this will be worth looking.
Shooting a long graffiti does not work with one picture. In the next video I will show you how to photograph a very long graffiti.
Camera for manual control. Take each image while the camera is parallel to the graffiti and at the same distance and height. Do not change the zoom.
