Reducing the Number of Faces

[IQCrash]

Hello everyone. I downloaded the Hunyuan3D-2-WinPortable version to run on Windows 10 with an RTX-4070. It works pretty well and most of the output is good. At least for me it works much better than TRELLIS.

However, I have one problem with Hunyuan3D-2, and that is the number of faces. When I import the .glb file into Blender, the number of faces is always 40,000, even if I use an image of a low poly object. This in turn makes the 3D model very large.

Is there a way to change some parameters to reduce the number of faces? I have looked in the Python scripts but have not been able to find these settings.

Any help or advice would be appreciated. Thank you very much!

Try messing with

Thanks a lot! That worked.

Edit: One thing that is noticeably different when reducing the number of faces to about 5000 was the computation time, which took 3 to 4 times longer than before.

Replace your gradio.py file with this one I made, it'll give you a slider to control it directly in advanced tab. Though i've set the lowest value to 20k, you can adjust that in the code, It's also set to change in 1k increments,
this line - max_facenum_slider = gr.Slider(maximum=150000, minimum=20000, value=40000, step=1000, label='Faces')

(wont work without the rest of the changes in that file adding first!)
