Creating a Mesh from Scratch with Python

Learn to create 3D meshes using Blender's bmesh Python module in this tutorial! Master getting references to vertices, edges, and faces and learn about Python's list comprehension feature. This will be a fast-paced, step-by-step guide for taking your Blender Python skills to the next level. #Blender3D #Bmesh #python

Python with blender is extremely powerful and let me tell you that you are doing a wonderful job taking all the complex documentation stuff and bringing to the audience such beginner friendly tutorials!

Perfect tutorial. Speed is good, simple enough. Thank you.

Personally, I could do without the music :-) While toying along, I'm pausing all the time, so I'm not enjoying the music anyway.

Great tutorial! I just started to use List Comprehension and it sure simplifies things, but is a little hard to get use to after doing it the old way! LOL! Keep up the great work!

Ur the best tutorial vd incould say frfr

i really love your content man, its priceless!!
Thank you so much for share it with the comunnity ^-^

Nice! Inwas looking at an API from a 3d foliage provider. They have modules for their own models and I got it working exporting obj files. Now using this to make blender models directly in blender will be way faster. No need for export and than import

I was wondering if there would be a speedup if we use bumpy. This is just a small model. I'm thinking of using it to generate foliage. I've got the data in different kind of arrays. It's basically on big list, so I need to first make an array of 3. Wonder if nunoy will be faster

Thanks for the new information! Please tell me if the channel has content on programming tools such as bpy.ops.mesh.loopcut_slide or loop tools?

[RomboutVersluijs]

Did you get those face indices by actativating the overlay for that. Was wondering how your got those numbers

[davedumas]

it has a hard time with geo nodes but if i feed it your "helper code" first and it does much better it only had a hard time with the names of the geo nodes so i just put a dict with a list of a bunch in the code before i post to GPT and it does much better

I want to know how to do procedural modeling, such as creating a custom shape and then adjusting the width and height, or shape.

[RomboutVersluijs]

Which video is the follow-up for this one?

[wissammmax]

thanks alot for your beneficial content

I am writing add ons with geometry node. How knows, how to read object/mesh from node input and how to set object/mesh in node output? I can't find anything

[davedumas]

have you attempted to play with chat-GPT for writing scripts for blender kinda fun!

how to read a binary file that contains an object and create it to blender ?

[RomboutVersluijs]

I'm confused why you run a sub for loop for those fave_vert_indices. It's basically a list of 4 items. So why do you run another for loop on each. Each item in that vert_ind8ces, only consist of 1 item, a single number. Or are you getting the coordinates of each face vertices. Not sure how the code reads that from only using index. I guess these are not random names, they are actually bmesh names for the attributes

I tried to list the meshes in Blender 4.0, but it didn't work. Here is the code I would get:
>>> import bmesh
>>>
>>> bmesh.ops.create_
Traceback (most recent call last):
File "<blender_console>", line 1, in <module>
AttributeError: BMeshOpsModule: operator "create_" doesn't exist

I also tried "create" without the underscore, but would get the same result.
I would love to know, how to call the available meshes in bmesh though 😥

Hey thanks for the tut u made. I was wonder if you could do me a flavor ? I tried doing some research on how to get the best score 'python bge ', however it's too complicated to make out with how to make use of any of it . Below this is the code i that im using . I have some ideas on how to add a best score in this fashion , Scene 1 save current score, Scene 2 load current score, and Scene 3 load best score . However I was wondering if you could make some sense how to do this ?

import bge
from bge import logic

path = logic.expandPath('//')

def save():
cont =
own = cont.owner
info = own ['Text']
file = open(path+'The_Score.txt', 'w')
file.write(str(info))

def load():
cont =
own = cont.owner
info = own ['Text']
file = open(path+'The_Score.txt', 'r')
line = file.readline()
print(line)
own ['Text'] = int(line)
