Error light on the textured mesh

[zhaoyunnick]

Hi does anyone meet the same problem? I use the default configuration to run the kitchen scene from mipnerf360 datasets, But the light on the textured mesh seems be wrong. The light on the side with main object is very dark, and the opposite side without object is bright.

Hello @zhaoyunnick,

It seems that the problem does not come from the texture of the mesh, but the lighting in your software. Since we extract the texture from the input images, the shadow and lighting are already baked in the texture, and there is no need to apply a lighting shader on top of it.

However, the default setting of your software seems to instantiate a light source under the scene, which is why it looks so dark from above.

You should probably change the light source, and look for an "ambient lighting" setting, with intensity 1. An ambient lighting will just display the colored texture without computing any additional shading, which will produce a good-looking results that will be much more similar to your input images. Here is an example of the mesh I extracted from the same scene as yours, with ambient lighting:

I also recommend using our dedicated SuGaR viewer, as it allows you to visualize the hybrid representation (Mesh + Gaussians) as well as the textured mesh with an ambient lighting, just as I explained.

I hope you will find this message helpful!
