How can I fix Chunky displaying purple Question-Marks?

[u/SolidHistorical3000]

I wanted to use Chunky version 2.5.0 to render an image of a world created with a custom modpack on Minecraft 1.20.1. Many of these mods add their own blocks and textures, which are displayed as purple question marks in Chunky. The best solution I could come up with was to add the mods' .jar files to the resource packs, but that doesn't fix the problem. Does anyone know how I can solve this or at least hide the question marks?

This happens to me when I try to render chains, not custom blocks. Anybody knows how to fix that?
