The simulated annealing algorithm seems to be unable to find the correct scale parameters.

Hey, I have bought the Adobe Substance 3D Designer 2023 in steam, and installed it on my ubuntu 20.04.
After I give the current toolkit-path and run this command "python test_nodes.py sbs/match_v1/ceramic_tiles_green.sbs", it reminds me that :

So, What went wrong? Do I need to revert to use SAT?

When I use the option "-e" : "python test_nodes.py sbs/match_v1/ceramic_tiles_green.sbs -e", there is no error! Why 0.0?

Thanks for your excellent work. I have some trouble in testing the library.
I run "pip install .", and then run "pip install -e ." and then Exit the cloned repo and verify package integrity with:
cd ..
python -c "import diffmat; print(diffmat.version)"
(I haven't installed the AS3D or SAT, but it will not affect this issue.)

But! module 'diffmat' has no attribute 'version'

hi, i try some sbs files that i download from substance 3d asset website, and i always encounter this problem. can you take a look for me, thanks
python test_nodes.py sbs\mytest\chamfered_concrete_building.sbs -e -b -g

Hi, and thanks a lot for releasing this code!
Since the license is non-commercial, could you please add a note in the README about the availability of a commercial license for diffmat, as well as a POC at MIT and/or Adobe to discuss that?

As title, I'd like to run the test script. It shows that the configuration file for node type: bnw_spots_3 for graph concrete_raw_panels.sbs is missing. Any helps will be appreciated! Thanks!

I noticed that the input parameter is required: parser.add_argument('input', metavar='FILE', help='Path to the input *.sbs file')
But your paper use a database of procedural materials, and use a special method to search a procedural material. So where is the database and the code of searching?
Sorry to bother you, I'm new to this research field.
Thanks to your reply, best wishes to your research.

Thanks for your good work. It's amazing so I want to follow it. But I have some trouble installing the AS3D or SAT.
Is it necessary or optional to install the AS3D and SAT?
If it is necessary, how about just install SAT? (AS3D seems not free)
How to install SAT? I just can find the installation of Pysbs in (https://helpx.adobe.com/substance-3d-sat/pysbs-python-api/getting-started.html) which seems not related to sbscooker and sbsrender.
Thanks for your reply.
