Basic questions about use Blenderproc - Beginner User

[MayconSilva7]

Hello guys. Look, when I run the quickstart, how can I set frames amount? Because, in he "How key frames work" tutorial, I saw it's possible to set adding a "frame = n", where n is the time. But, I have tried to set in the camera, object and light. But still it isn't working, and It's setting 250 frames.

Thank you in advance.

All right, I am using VSCode interpreter.

import blenderproc as bproc

import numpy as np

use_only_cpu=True

# Create a simple object:
obj = bproc.object.create_primitive("MONKEY", frame=2)

# Create a point light next to it
light = bproc.types.Light()
light.set_type("SUN")
light.set_location([2, -2, 0])
light.set_energy(300)

# Set the camera to be in front of the object
cam_pose = bproc.math.build_transformation_mat([0, -5, 0], [np.pi / 2, 0, 0])
bproc.camera.add_camera_pose(cam_pose, 2)

        
#blender new line
bproc.renderer.set_render_devices(use_only_cpu=True)


# Render the scene
data = bproc.renderer.render()

# Write the rendering into a hdf5 file
bproc.writer.write_hdf5("output/", data)

Why did you remove bproc.init()? For me it works

$ blenderproc quickstart

'blenderproc quickstart' is an alias for 'blenderproc run

I have removed because, in my pc it wasn't working, I got an error. So, I set only to use CPU (I also have spoken with about this).

Regarding the code, sorry the stupid question, but I run the code as following:

blenderproc
blenderproc quickstart teste

"Teste" is the quickstart same code.

It runs until 250 frames.

When I call:

blenderproc run teste

I got an error.

no sorry, don't have time for this. I advise you to brush up your python skills before using BlenderProc

[MayconSilva7]

I am sorry to disturb you. I am lerning Python too. It is because I have used Python scripts on Blender. But now, I need to do an application for my paper. I need to import a geometry (also designed in Python) in Blenderproc and take cameras of her. For this, I need to use Blenderproc.

I am really sorry, I don't want your answer for me. Thank you very much for all your help.
