Material Properties for lighting of image plane
Hello all, I'm using gz sim 7.4.0 and I'm attempting to create a visual flat plane in my world that shows a .png file of a google earth view of a section of land I'm interested in. I can successfully load the image and see it in the model no problem, however it seems to be extremely desaturated and much darker than the original image when it's loaded in. I have directional lights in my world file and lighting properties for the material element for the image, and I've tried a number of different combinations of lighting properties with no luck.
Is there a simple way for an image to always show its original brightness and saturation instead of relying on a light source, and if not, does anyone know a good set of ambient, diffuse, specular, and emmisive values for this sort of thing? Thanks!

How did you add the png to the model? Are you using a mesh file?

From an example online. I was previously just loading a .dae file into the mesh section of the geometry but it was drastically lowering performance.

Can you try to put it in the
emissive_map
? Not sure it would work, but from using blender, I've learned that if you don't want textures to be affected by lighting, you put the texture inemissive
