Render video with custom camera path, mapping extracted matrial to different mesh

[prakashknaikade]

Thanks for great work.

1. How we can render video with custom camera path like nerfstudio with original/other lighting envs?
2. How the relighting video shown on project page is rendered?
3. How to map extracted material to different object's mesh?

Hi, thanks for trying our codes.

1. The current codes does not support arbitrary camera paths. You may need to implement it yourself.
   For 2. and 3., you may refer to the rendering scripts of relighting.

Hi, thanks for the reply.
From where we can access extracted lighting env (.exr) to use it in rendering scripts of relighting to render video with original lighting env? @liuyuan-pal @ingra14m

Hi, the released codes do not provide interfaces to extract lighting env. You may need to refer

NeRO/network/field.py

Line 564 in 3b4d421

direct_light = self.outer_light(ref_roughness)

to extract the env lights and save it as an .exr file.

Hi, thanks for the reply.
@liuyuan-pal Can you please elaborate little more about the solution you provided?
I just want to render the original scene from estimated BRDF, mesh and lighting.
