I recently started to use URP and I am noticing a weird blue like tint on shiny objects that use the URP/lot shader and I can't understand what it is and how can i remove it.

And while there is no skybox visible in your screenshots, they tend to have light blue in them. \$\endgroup\$Philipp– Philipp2021-03-11 12:28:13 +00:00Commented Mar 11, 2021 at 12:28
- \$\begingroup\$ Yeah that could be the case. Its probably from there as the skybox is the same color. Thank you very much. \$\endgroup\$RoboAbathur– RoboAbathur2021-03-11 23:13:08 +00:00Commented Mar 11, 2021 at 23:13

This appears to be colored light emitted by the skybox.
When you don't want the skybox to act as a light source with the color of its textures, then
- Open the lighting window (Menu entry Windows->Rendering->Lighting)
- Go to the "Environment" tab
- Change the "Source" under "Environment Lighting" from "Skybox" to "Gradient" or "Color". You can then select the color of the ambient light. If you don't want any ambient light at all, set the ambient color to pure black.
It is also possible that this isn't actually ambient light, but actually a reflection of the skybox. This would explain why it only appears on "shiny" objects. When you want reflections on specular materials to reflect the actual environment around them, then make sure you scatter some reflection probes around your scene. But keep the performance concerns in mind.
