Environment Map for PBR
This is information for "Image" Project element I found in Document:

"Environment - Same as "Cube Texture" except its mip-maps will be blurred in a special way, allowing it to be used as Environment Map for PBR"

Then I copy Tutorial's skybox to my project and convert it to Environment. I make for m├Żelf a random skybox too

As my expectation and understanding, This will give a PBR material the reflection of the skybox (which is Environment Image). I create an object and apply material on it, change material parameters but there is no reflection. and no difference between 2 skyboxes

This is my skybox https://i.gyazo.com/2fd50b264c89cb7278ac...ff2848.png

and This is tutorial skybox: https://i.gyazo.com/485aa11cdfbc020c1864...96619d.png

when I set Reflectivity and Smoothness to maximum, and replace my object with a sphere, that material just reflects the same thing, like this https://i.gyazo.com/c3285960ed285787b312...e9bc3e.png

It seems to be the static horizon of sky without skybox.

Doesnt environment mode for image work ? Or I misunderstanding something.

Please explain smile Thanks !

I really want to make this building's glass pane side to reflect a little bit of skybox, even blurry cloud

PS: Btw I realized that there is no slot for environment map of material, what happened?

RE: Environment Map for PBR
reflect_mul , // reflectivity from metal texture 0 .. 1 , default=1-MATERIAL_REFLECT
reflect_add , // reflectivity base 0 .. 1 , default= MATERIAL_REFLECT

i found that under the material, is the metal texture to add reflectivity set up correctly ?
maybe show us the material settings, that might help

my wild guess is that there is probably no reflection done from the skybox.

best option if that is the case is to reproduce this with a mix of assets, clouds and skybox
