Ok, so this is kind of a part two to my previous post. I'm still having standalone issues.
So, I finished building my game, and people have been reporting that the terrain is blank. I install it myself and lo and behold, it is blank.
All of the configuration files are there, the standalone .exe is there, the files are there, so nothing should be missing.
The only thing that might be throwing it off is the files that the installer throws in. There's uninstall .DLLs and an uninstall .EXE, but GameGuru doesn't call for these...
Any help?
The installer download is here: https://officialnerfrhett.gamejolt.io/virtualfiringrange/ (One with the empty terrain)
The .ZIP file (directly from Documents/Game Guru Files) is here, it should work: https://drive.google.com/file/d/18cid4CqirTR8PFcLOhmiPCD_-427CW_Q/view?usp=sharing

looking into this, just downloading your files, see what's going on if possible.

got this error so far , but still looking into it.

no empty terrain my end, looks alright from here:

Meant to.mention that I used the installer and all ok except the error I got above

The installer version failed but the zipped worked.
Im guessing the problem lays with the installer creation.

As it's a new issue to me I would agree. I've seen missing objects, invisible objects, weirdly rotated objects. But never NO objects!

@ Nerf Rhett Games
The issue with the missing exe file is becuase the file point to a wrong path C:\Program Files (x86)\Nerf Rhett Games\Virtual Firing Range\Files while your exe file sit in [i]C:\Program Files (x86)\Nerf Rhett Games\Virtual Firing Range folder, in order to bypass that issue you could do:
1- Fix the path in your installer.
or
2- copy/paste exe file within your files folder.

I've tested your game in my laptop and it is unplayable for me due to the few fps I get, anyway I'm going to test it in my desktop as far as possible, I'll back when done. Specs on mi sig.
Ignore how those GG files added to standalone file manage all the stuff paths, fpm internal files point to C:\Program Files (x86)\Steam\steamapps\common\Game Guru\Files\mapbank\Virtual Firing Range.fpm and your point to C:\Program Files (x86)\Nerf Rhett Games\Virtual Firing Range\Files\mapbank
Assets point to:
\Mega Pack 01\Buildings\Lookout Tower.fpe
\Mega Pack 01\Foliage\Desert Plant 03.fpe, and so on.

I hope standalone working with installation folder, as root folder.

Ok, so it looks like I just have to fix the installer then. I’ll get on that. Thanks for everyone’s help.
This is my first game made with GameGuru Classic, and seeing as the community is very helpful this gives me hope. I’ll learn from my mistakes next time, and hopefully it’ll be okay.
