(Or something) When trying to load with Maraxis and planetaris dyes it states there is an error with art pixel sizes. I just went through and changed them to the listed expected sizes and it worked. Don't remember what exactly they were but just letting you know.

Are you running Factorio 2.1 or 2.0? And what specifically did the error say? It would be helpful to know if it was referring to the item icon, or the entity rotations.

Startup error:

The given sprite rectangle (left_top=0x0, right_bottom=196x274) is outside the actual sprite size (left_top=0x0, right_bottom=196x273).

Thanks for the error. Should be updated now. I'll leave the thread unlocked for a bit in case you encounter any more errors, otherwise I'll close it in a few days. Issue was the sprite-bounding being mutated across across all four rotations, so the fix was just explicitly defining them.

Hey again, I've got another error message(this time I included it below). Reverting back to my 2026.07.18 version in which I manually changed the sprite size worked again, so it should be the update. To clarify, I opened up the images in asperite and saved them as different sizes.

In prototypes/entity.lua

entity.icon = GRAPHICS_PATH .. "heat-boiler.png"

There is no "heat-boiler.png" in graphics dir

Grrr...knew there was something else still. One sec.

Fixed, for real this time. 😅
