in this file i have some objects that dont show up in final render, i check in restriction, the “disable in renders” isnt active. i have read some QnA about this similar problem, the answer of this problem is checking the “disable in renders”, make it inactive. but like i said mine is already inactive, so i am confusing right now… hehhe
Since i am a new user, i couldnt upload any files.
You’re missing a lot of texture map files - that’s what you’re seeing as purple.
You have a lot of objects that are indeed hidden in the object manager, but as so many are named “cylinder” it would take too much time for me to determine if they actually are wanted to be hidden, or not.
Most likely you have just pressed the wrong button(s), because by default it should be turned on:
If you encounter problems like these, you may always reset your Blender’s settings to default ones, by going to File → Defaults → Load Factory Settings, see screenshot below:
