Questions about image_based_lighting:

1. In the supplementary material, the description of creating shadow_map with normal is not clear. Are the terms' shadow map 'and' shading map 'problematic in this paragraph?
2. in the preparation of In-the-Wild dataset, albedo_map, normal_map, env_map[HDR], shadow_mask, shadow_map were obtained, but how was the subsequent IBL implemented? Which reflection model is used?

Questions about ienvironment-from-normal-method:
3. environment-from-normal method: Is the obtained environment-from-normal reasonable according to the section around supplement L67-73? I wonder if the new shading map rebuilt with the resulting environment map is consistent? If not, can the environment map obtained by this method really be used as an "environment"?

I would appreciate it if you could provide details or know me!
