ValueError: No blender available! #1

Open SeungHunJeon opened 5 months ago

SeungHunJeon commented 5 months ago

When I created the conda environment according to the description, there were two conflict errors regarding 'perlin-numpy' and 'wfc-python'.

Then, I manually annotated two lines in 'environment.yaml' file,

(I think the wfc is already defined in the terrain-generator project, then I ignore this issue)

and installed perlin-numpy via the following command: pip install git+https://github.com/pvigier/perlin-numpy

It seems that you haven't installed blender. Run 'sudo apt-get install blender' will solve this problem. But then I meet another problem.

Thanks! I resolved the previous issue.

I also encountered the identical error message.

Thanks for the report! It seems like the blender is failing to merge some meshes. Could you try setting the minimal_triangle param to false to check if it works?

Yes! I've tried to do that before and the code works. So I think it's something wrong with blender. But I can't figure out why up to now.
