Cleanup Map Tiles Fast Using Blender 3.6+

UPDATE - June 2024 - The script is now working with Blender 4.1
In this video we look at how to clean up a photogrammetry mesh automatically with a python script and the improved Blender 3.6 UV unwrapping tools.

Epic. Thanks again!

huge thanks mate!!!!

Awesome video and script! Any tips on how to further clean up the model for a nice 3D printable STL?

Brilliant! 😘

Anyone else still getting black materials? I am using 3.6 and also modifed the script ot incluede bpy.ops.object.bake(type='EMIT'), but not having any luck/

[@jamesriley5057]

Very well done video. Sub'd. I would also love to cleanup the mesh into quads - even if it took a whole weekend of processing.

[@smyrkphace]

should this work in blender 4? I just got error expecting 1

[@salyiohh]

What if you zoom in to approach the road does it distort the mesh

[@aeonbreak4728]

can you make that into an addon button for the N panel? would be helpful instead of having to copy paste that every time :)

[@Viktorr87]

This is exactly what I'm looking for in order to export the textured mesh to Rhino. Unfortunately, I get the following error after hitting the Play Button: Python: Traceback (most recent call last): File "/Users/viktor/Downloads/231205_Hafenstrasse_3D_Blender.blend/Text", line 102, in IndexError: bpy_prop_collection[index]: index 0 out of range, size 0 Any hints for a solution?

After a successful run of the script on 3.6.7, I started over and tried again, but I keep getting a similar error: Step 2 | 369 / 0 | 100.0 % | Removed material.

hey! All the meshes join which is great, but but the texture doesn't save, they all get dropped and there is no image for me to save. do you have any advice? thanks :)

[@ile5607]

How can i adapt this to batch all objects in the scene without joining them?

Hello @Nicko16, can you make a tutorial how to convert ply file to obj file using blender. I am having a hard time converting to obj files. I can convert but there is no color included. Thank you

Hello, may I please ask why is it that after running the script, my texture is all black?

[@markrussell67]

change this line in the script from 'DIFFUSE' to 'EMIT' (if you want to know why, look at the materials that came from google, they all use emission nodes) bpy.ops.object.bake(type='EMIT') this only works in Blender 3.6, running the script in Blender 4.0 has other problems

this is because you need to select the collection in the viewlayer window

Hi Nicko16, do you even work out a little hillside city near to frankfurt in order to 3d print ? ;) (b-day presend) - for sure against beer creates ? forgett coffee;) Or maybe you havev ~10 scrips which will do this :) Blender & Co are to powerfull for one usecase to learn......

[@hectorgonzalez6287]

Hello, Followed your Tut and found it excellent and very helpful. . I was wondering if you can explain a process for trimming/clipping a model brought in via the BLOSM Blender method. In other words to clip our unwanted areas so it more clearly defines only your desired space on a map model. You can IM me if you like. THX!

[@rando8841]

Looking for the same info. Any attempts to cut the model results in a huge mess.

[@mtscott44]

I've tried twice now, but I get a grey texture at the end...and it's not called "collection_texture". Any clues?

[@Nicko16]

I looked at the code and your texture should have the same name as the collection that was active when you started the script, so confusingly, it may not have the same name as in the tutorial.

@@philhighfield4741 try downloading the newest version of Blosm they fixed it as best as they could.

[@SwedishObjects]

Had the same error when I tried using geometry created in Blender 4.0 in a Blender 3.6.9 file. Then tried creating a new blend file in Blender 3.6.9 and use Blosm there, import new google maps tiles in this older blender version and run the script, then it worked. But got black textures and had to change the DIFFUSE to EMIT like a comment below suggests. Then it worked perfectly.

[@nn84zz]

I am having the exact same issue on Blender 4.0. Please update the script.
