Does this work in windows?

[steven850]

Hi, this elements work with blender in windows or is this linux only?

[bestman8]

it works for me and i have windows
it isn't easy to install

[steven850]

Well I followed the steps in the readme which where useless to be honest. Manually installed everything, but when I go to enable the addon in blender, blender crashes to desktop. Using 2.83.5 LTS

Could you run blender in console (cmd) and attach the output here? Related issue: #54 (comment).

The install location seems make Blender consider taichi as a plugin while it's not..

Does http://github.com/taichi-dev/taichi_blend, which does not require pip for installing taichi work for you?

[steven850]

that seem to work

import taichi as ti

Sorry, I forgot to add extra dependencies like taichi_glsl to Taichi-Blend.zip.. But mpm3d.py should work?

[steven850]

mpm3d loads a point cloud into the 3d viewport. Can play it but cant make any other changes. Im assuming thats correct?

[archibate]

Yes, if you press the Space button to start animation, the point cloud will move like liquid. Otherwise it will raise some error in console.

[steven850]

Yes it does. I also downloaded 2 of the demo blend files. They dont seem to work properly, 2 of the nodes show as undefined. Is this because of the missing glsl or have the demo blend files not been updated?

[archibate]

Yes it does.

Great, then we can confirm taichi is working well in Windows+Blender, with taichi_blend.

I also downloaded 2 of the demo blend files. They dont seem to work properly, 2 of the nodes show as undefined. Is this because of the missing glsl or have the demo blend files not been updated?

I can't make them functional too, keep getting this error:

I run utils/install_blender_addon.py, and it doesn't even functional when cwd is not utils. The required environment variable BLENDER_USER_ADDON_PATH is also not found in README.
I'm wondering if we could make things less complicated? Why don't we just simply move blender to taichi_elements.blender? It's not a big disk usage for non-Blender users, compared to taichi_core.so which is around 50M.
@yuanming-hu You said in GAMES 201's final lecture: simplicity matters. So why is our installation process of taichi_elements getting so complicated, compared to taichi_blend which bundle all dependencies into single ZIP archive like all other Blender addon does?

In fact the cwd problem can actually be easily solved by:

- taichi_elements_path = os.path.dirname(os.path.abspath(os.curdir))
+ taichi_elements_path = os.path.dirname(os.path.dirname(__file__))

... why os.curdir...

[steven850]

This is the error I get in the console when opening the demo blends.

and the file opens but the simulation doesnt work. See screen shot of nodes.
