Still no texture after add the --textured

[dolcelee]

First of all, amazing work! I tried a portrait dataset, the mesh looks good. However, it still shows no texture after I added "--textured". I use Meshlab and Blender to view ply files. Did I miss anything? CHECKPOINT=logs/example_group/example_name/xxx.pt OUTPUT_MESH=xxx.ply CONFIG=projects/neuralangelo/configs/custom/${EXPERIMENT}.yaml RESOLUTION=2048 BLOCK_RES=128 GPUS=1 # use >1 for multi-GPU mesh extraction torchrun --nproc_per_node=${GPUS} projects/neuralangelo/scripts/extract_mesh.py \ --config=${CONFIG} \ --checkpoint=${CHECKPOINT} \ --output_file=${OUTPUT_MESH} \ --resolution=${RESOLUTION} \ --block_res=${BLOCK_RES} \ --textured

Thanks for reporting. This is a known bug, will fix it in the coming days.

I see the same issue but for me, it shows texture if I use the first checkpoint but no texture for checkpoints after the first one.

@chenhsuanlin Is it really a bug? It didn't work for me when I wrote it the way the author of the issue did, but when I wrote it the different way everything worked. Just placed the command in the beginning and added backlash after it.

--textured \ --config=${CONFIG} \ --checkpoint=${CHECKPOINT} \ --output_file=${OUTPUT_MESH} \ --resolution=${RESOLUTION} \ --block_res=${BLOCK_RES}

I have the same issue.

Thanks for the data point, I tried this way but still didn't work. However, when I changed to the first checkpoint instead of others, the texture shows.

Thanks for the data point, I tried the first checkpoint, the texture shows as you said! The performance is not good unfortunately

[Bai426]

@dolcelee Sorry, I didn't see the texture yet with the first checkpoint and the above scripts, not mentioned using other checkpoints. I also noticed that the 3d model is very rough in the first checkpoint.

Hi @dolcelee @Bai426 @ftn-gautam

Sorry for the late reply.

• Can anyone confirm if they see an output of "Failed to convert color" in the terminal when there is no color?
• If possible, could anyone upload a copy of the config and the checkpoint they would like to use so I can look into this?

[dolcelee]

@mli0603

• I didn't see any error message in the terminal when there is no color. It shows color[127,127,127,255] something...

• I uploaded my dataset, contact me if you need anything else

Thank you @dolcelee

This is likely a bug related to #75 where the loaded checkpoints fail to predict any colors. We are looking into this now and will circle back.

[mli0603]

We have pushed a commit that potentially fixes the issue of mesh extraction (https://github.com/NVlabs/neuralangelo/commit/c91af8d5098c858df8e8dfa35fba8666d314782b). Please let us know if you still run into the same problem.

[Bai426]

Thank you very much.Yes, I tested and found that the texture can be seen on any checkpoint. The only issue is that the reconstruction result has some noises like what dolcelee showed above.

Best, Mike

@mli0603 I retrained the same dataset and regenerated the mesh. It shows the texture but looks weird. I think this problem is related to the bounding sphere. Could you please tell me how to set the value of the sphere?

[mli0603]

Hi @dolcelee

Good to know that textured mesh can be extracted. For sphere adjustment, please see DATA PREPROCESSING.

[mli0603]

Closing this issue as it is resolved. For other issues, feel free to report in a separate thread.

@mli0603 I used the latest version of the code, but the exported mesh still has no texture. Is there anything else I need to pay attention to?My export script is as follows：

_GROUP=fc_example NAME=fc_example_0831 CHECKPOINT=logs/${GROUP}/${NAME}/epoch_00053_iteration_000020000_checkpoint.pt OUTPUT_MESH=yzfc_53.ply CONFIG=logs/${GROUP}/${NAME}/config.yaml RESOLUTION=2048 BLOCK_RES=128 GPUS=1 # use >1 for multi-GPU mesh extraction torchrun --nproc_per_node=${GPUS} projects/neuralangelo/scripts/extract_mesh.py \ --textured \ --config=${CONFIG} \ --checkpoint=${CHECKPOINT} \ --output_file=${OUTPUT_MESH} \ --resolution=${RESOLUTION} \ --block_res=${BLOCKRES}

[chenhsuanlin]

@lie12huo the checkpoint is likely corrupted from the previous (buggy) code. You would need to retrain the model for this case, not just re-extract the mesh.

[lie12huo]

@chenhsuanlin I used the latest code to preprocess and train checkpoints today, but the exported model still has no texture.
