[ENDED] BC1-1808 – August 2018 Class Homepage – Getting Started with 3D Modeling & Blender 2.8

[silentheart00]

I am commenting here to test the “remembers your spot” feature because it keeps pulling me back to a previous spot when I’ve read farther ahead.

@thecabbagedetective Loading files in 2.8 can be a bit of a hassle sometimes, as far as I’ve seen in the streams of Pablo Vasquez (Blender Today), but I suppose it will be better over time.

I myself have only loaded a couple of files, and at least one of them made blender crash.

It’s advised to keep a backup of your 2.79 files before working on them in 2.8, because it’s impossible to load the file back in 2.79 ones you edit them in 2.8. I managed to get a file from 2.8 to 2.79 by exporting to an Alembic file, and then importing that in 2.79. It wasn’t a very clean import though.

Also, modifiers in Blender 2.8 do not show up in edit mode.

Just in the mental preparation to the class found an inspiring way to complete the Week 1 exercise to model with primitives – it could be a fun practice to do that through a short Python programming. 

The idea is maybe a little bit for the advanced users, but you will see it is very simple and fast to run any Python code in Blender, so why not could be inspiring to show also for beginners.

Actually this code is able to select a random RGB color, switch the engine to Cycles, set the camera in the required distance and angle, then in a loop adding 25 cubes with assigning material to each with that random diffuse color. Look at this in five seconds:

Somehow finding this as very powerful, let me attach the code concretely, khmm such things could be used for a lot of automation:

import bpy
import random
from math import radians
def get_random_color():
 r, g, b = [random.random() for i in range(3)]
 return r, g, b

bpy.context.scene.render.engine = ‘CYCLES’
obj_camera = bpy.data.objects[“Camera”]
obj_camera.location = (25.0, -8.0, 17.0)
obj_camera.rotation_euler = (radians(51), 0.0, radians(53))
area = next(area for area in bpy.context.screen.areas if area.type == ‘VIEW_3D’)
area.spaces[0].region_3d.view_perspective = ‘CAMERA’
for i in range (0, 5):
 for j in range (0, 5):
  x = i*3
  y = j*3
  z = 0
  bpy.ops.mesh.primitive_cube_add(location=(x, y, z))
  cube = bpy.context.object
  mat = bpy.data.materials.new(‘material’)
  mat.diffuse_color = get_random_color()
  mesh = cube.data
  mesh.materials.append(mat)

It might be useful information yet if someone tries to paste Python code to the inside Python Console in Blender, that the indendation then should be with the space ‘ ‘ characters instead of the tabs. (you can see in the code above that in the for i in range and for j in range sections there are spaces, they are needed in Python). If you would like to reproduce it, after the paste I pressed two Enters for the running

@csehz That’s really neat!

[Aaron Rudderham]

@carrotnl  Aha, cheers for the advice. Loaded  one of my files into 2.8 and it worked fine, but I think I’m gonna stick to 2.79 until I absolutely have to swap for the class.

[Aaron Rudderham]

Right, so I gotta cram studying of 2.8, rigging, Substance, anatomy. topology (still) and hair physics into this month. What could possibly go wrong? My brain’s gonna melt haha.

[smurfmier1985]

@thecabbagedetective Wow, you really have something big in mind, that’s a lot! No doubt you can do it you’re a good artist, can’t wait to see it 🙂

[Kent Trammell]

@thecabbagedetective So far, 2.8 doesn’t seem reliably backward-compatible with 2.7x files. So if you have serious projects underway with 2.7x, I recommend not transferring those projects to 2.8. Simple 2.7x model files have opened fairly reliably for me in 2.8 but who knows about all the nitty gritty settings and parameters under the hood.

As for working on the homework early, I’m ok with it – It won’t affect your grade negatively. Just please post your homework to this thread during the appropriate week; not before 🙇🏻‍♂️

[Kent Trammell]

@silentheart00 Did your ‘thread memory test’ work? I too have wondered how accurate the feature is. Though I often have this thread open in multiple chrome tabs, on various pages, replying in various tabs – so that’s gotta be confusing to the feature 😅

[Kent Trammell]

@williamatics Indeed..I find that one of the bigger annoyances with 2.8 so far. No doubt it’ll be updated to function soon-ish.

[Kent Trammell]

@csehz Your post has single-handeldly inspired me to brainstorm a “Getting Started with Python in Blender” class. It will be so much fun! Thanks for the inspiration 🙇🏻‍♂️

[Kent Trammell]

@thecabbagedetective I don’t think anyone needs to commit to 2.8 100% now, during the class, or even after 2.8 is released. Nobody needs that pressure and stress lol. Just take it one step at a time and understand it’s absolutely OK to still work with, even prefer, 2.79 over 2.8.

[smurfmier1985]

@csehz Wow, I knew you could build addons with Python but this blows my mind, didn’t expect that! Awesome 😁

[Morten Fjellheim]

When it comes to the prercorded courses for week 4, are we talking about the whole learning flow? Isnt that abit much for a beginner class? Or are we talking about the first part or something?
