Good day gentlemen!
I'm making my first A1 scenario now, and it seems like I've ran into roadblocks already in the beginning... I've searched the internet and the Pfhroums for this during the last 2-3 hours, but haven't found an answer

So, I'm using ShapeFusion 0.6 and trying to make a custom skybox (replacement texture for Landscape 1, using Infinity Shapes file as a source). It looks alright in ShapeFusion (True Color version), and I have imported the custom color map and such, but when I'm using the Visual Mode Lua (again, under Infinity), the landscape is completely black! I'm completely puzzled; not to mention I've spent a lot of time trying to figure out what's wrong, uploading the image in different formats, etc.

Can you please advise on what may be the issue? I fear I might run into the same issue altered textures in Shapes
Here's the Shapes file I've modified:

Thank you very much in advance!!!
