The output of the original code renders the course model only (last column).  The output of the code from @425776024 renders the course model with a blending texture which...

Add `if(POLICY CMP0057)` `cmake_policy(SET CMP0057 NEW)` `endif()` before the 97th line of CMakeLists.txt. Reference: https://cmake.org/cmake/help/v3.19/policy/CMP0057.html?highlight=cmp0057

Thanks for your reply ! My device is HL 2, and I try the HL2ARToolKitSingle sample , the size of the marker I print is 4cm (a 4x4 cm marker...

I also try to replace texure model in [Photometric FLAME fitting](https://github.com/HavenFeng/photometric_optimization/blob/master/models/FLAME.py#L220) as referenc to @TimoBolkart 's [demo code](https://github.com/TimoBolkart/TF_FLAME/blob/master/sample_texture.py#L78)，but the optimization process would crash in the non-rigid fitting part as all...

Aha! It works! It turns out that some values in diff_albedo + spec_albedo are 0, which cause nan during the optimization. The coefficient 0.6 is set just to make diff_albedo...

@TimoBolkart Hi！ Can you explain more about the coefficient 0.6? That is different from what the original paper discribed.  I seems wrong to just replace texure model in [Photometric...

Finally I received a mail and get the password for the unzip file, but the dowmload link at the official website is invalid :sweat: Invalid link: https://www.dropbox.com/s/yf8a3btsn8fjdbv/Menpo_3d_challenge_trainset_videos%20%281%29.zip?dl=1

@jiankangdeng Can you help ?
