I have a problem that occasionally occurs when rendering premade assets. Namely, I create some assets so I can speed up my work but at some point, some or all assets that have been added to the new project won't render at all (cycles and eevee).
I figured out that somehow, an object inside of my asset has changed the render state, and I cannot find out why this is happening. I can see them when I use Make Instances Real and "unpack" the assets.
I'm sending some screenshots and one example in link below.
I appreciate it if someone could solve this mystery for me.
