Lack of `template.mtl` file

[pstorozenko]

Hi, these results are very interesting! However I keep getting the following warning:

UserWarning: Mtl file does not exist: /home/jupyter/DECA/data/template.mtl
  warnings.warn(f"Mtl file does not exist: {f}")

Where does template.mtl file should come from? There is no such file in yours archive, BFM nor FLAME model files. Am I missing something?

Enter on the command line：python demos/demo_reconstruct.py -i TestSamples/examples --saveDepth True --saveObj True

@lin-girl, thanks for answering! I've tried what you've written but I get:

And resulting obj looks as following:

It seems as template.mtl is not generated but should be delivered somewhere, am I right? Maybe I set something wrong and you quickly see what might be the issue, thanks helping :)

Add parameter --useTex True Try this command python demos/demo_reconstruct.py -i TestSamples/examples --saveDepth True --saveObj True --useTex True

[pstorozenko]

Thanks for answering @Nyquist0 !!! The results seem different but I still get the following error regarding template.mtl

And the resulting obj looks like:

However, resulting _vis file contains fitted texture, I don't know how to understand this.

Some help on how to obtain an obj with fitted texture, not glued photo will be much appreciated!.

I am having a similar issue regarding the lack of template.mtl - would appreciate any help on how to resolve this issue.

is it raise error from Pillow package? i guess you can follow this https://stackoverflow.com/questions/42462431/oserror-broken-data-stream-when-reading-image-file

from PIL import Image, ImageFile
ImageFile.LOAD_TRUNCATED_IMAGES = True

[pstorozenko]

Hmm, thanks for answering, but it's a raised by pytorch3d. Maybe I didn't explain it clearly, but the template.mtl file doesn't really exist anywhere on the disk. Should it be like that?

Hi, have you found the mtl file finally?

[lxzlwhy]

@pstorozenko HI , is there only have 5023 vertices in the reconstruction result obj file? But I see that he display have more vertices.

Hi guys, you can solve this error adding a template.mtl file on your own with this info inside: newmtl FaceTexture map_Kd mean_texture.jpg

Hi guys, you can solve this error adding a template.mtl file on your own with this info inside: newmtl FaceTexture map_Kd mean_texture.jpg @Javisda Hi, bro, I met the same issue at Emoca reference. Do you mean that I can write a template.mtl file with newmtl FaceTexture map_Kd mean_texture.jpg which can fix this issue?

[zardamhussain]

Hello @Javisda Can u tell where is map_Kd mean_texture.jpg
