Issues on loading large obj files

engine.zip

I get the following error when loading large obj files. I have attached the concerned obj file and the code file as well.
3d_render.zip

kivy.graphics.vertex_instructions._ensure_ushort_view OverflowError: value too large to convert to unsigned short

checkers.py crashes on a touchscreen with kivy 2.1

On a desktop with a mouse everything works ok.
But on a touchscreen, HP All-in-One system the checkers.py crashed. I suspect the problem lies in the fact that on a touchscreen a "touch_move" event is generated iso a "touch_up/down".
Both systems are Ubuntu 22.04 with a python v3.8 virtual environment with kivy 2.1 installed and the kivy3dgui placed inside the tree.

To reproduce, start checkers.py and touch any stone.

This is the complete traceback:

on_touch_move crashes the checkers app in kivy 2.1 on a touchscreen

To reproduce: Start the checkers example and generate a "touch_move" event a stone on a touchscreen.
It will crash.
See also my pull request for a syntax fix. (This only fixes a crash on a non touchscreen)

Positioning and sizing nodes in 3d canvas

Hi dear sir,
I would like to know how to set a node parameters to adapt position and size. For example, I would like a node to be a button which can rotate on pressed. Imagine in your checker example. You have two buttons in the left top corner. I would like these buttons were two nodes and they stayed in that position as window resizes and changed size accordingly.

Best regards

Objects not showing correctly

Any idea why this happens for some objects?

from kivy.app import App
from kivy.lang import Builder

class ExampleApp(App):

    def build(self):
        root = Builder.load_string('''

Layout3D:
    id: par

    Node:
        id: Node1
        name: 'Node 0'
        rotate: (270, 90, 0, 0)
        # scale: (0.2, 0.2, 0.2)
        translate: (0, -10, -50)

                Color:
                    rgb: 1, 1, 1, 1
                Rectangle:
                    size: self.size
                    pos: self.pos
        ''')
        self.root = root
        return root


if __name__ == '__main__':
    ExampleApp().run()

Suggestion: default mesh for a Node

In order to work 'out of the box', would it not be best to have a default mesh that displays as close to standard FloatLayout as much as possible.

The aim to to have it just work, with as few 'surprises' as possible e.g. having to create a mesh. Many users will now know what a mesh is, so a default, simple mesh makes sense?

AttributeError: 'NoneType' object has no attribute 'add_node'

I just discovered this repository, when I tried to executed this error pops up

AttributeError: 'NoneType' object has no attribute 'add_node'

I'm working with the 3d_editor branch.

Any hint of what could be?

Thank you and regards!
