On the IR3 Patchset, I believe you offered to provide graphics for the "turbo" loader and stackers which would be unlocked from Vulcanus. I'm here to take you up on that offer.

I don't know how you made these graphics or whether they're derived from the IR3 originals in any way. Since I'm trying to minimise the Patchset's liability, and "Powered Loaders & Ingot Stacking" already depends on Black Rubber Belts, I think it might be best to include the graphics in Black Rubber Belts. It also means that you can easily update them if you need to.

There's no rush to do this, I won't be needing them for a long time.

Hello! No problem! I'll update the mod to include the graphics in there just for you. :)
Just replace the correct layers in the entities and it should work fine. (For the stackers' inner mechanisms, you can use the 3rd row of the "beltbox-working" sprites)

The paths for all the graphics will be the following:

__black-rubber-belts-remastered__/graphics/entities/turbo-beltbox-base
__black-rubber-belts-remastered__/graphics/entities/turbo-loader-base-front
__black-rubber-belts-remastered__/graphics/icons/64/ir3-turbo-beltbox
__black-rubber-belts-remastered__/graphics/icons/64/ir3-turbo-loader
__black-rubber-belts-remastered__/graphics/icons/256/ir3-turbo-beltbox
__black-rubber-belts-remastered__/graphics/icons/256/ir3-turbo-loader

I'll make sure to not change these

I'll let you handle the coding part though... the "powered loaders & ingot stacking" mod is kind of obtuse when it comes to adding a new type of loaders/stackers.
(By the by, if you need any extra custom graphics based on those of IR3, I can upload an extra asset pack as a separate mod. For instance, for new parts or the spatial science packs.)

Thank you. I get this error trying to load 2.2.2:

File __black-rubber-belts-remastered__/graphics/icons/64/settings/alt-bases.png not found

I think additional graphics can probably go into the add-on directly, I just asked for these two to be in BRB because they're belt-related and it would fit.

I'm not sure what to do about graphics such as the spatial science packs. What I've done currently in the add-on (and I do this for Quality modules as well) is to take one the existing analysis pack icons and tint it. It doesn't look great, but I don't have to distribute derived assets that way.

EDIT: Apologies for inadvertently causing you this trouble. For what it's worth, I did manage to get the entities working in-game.

[The 2.2.2 crash]

Ahh no yes that's a problem on my end no worries. I forgot to properly change the filepaths after modifying my own code...
It's just me changing code without understanding the code all that well. (and forgetting to test it) ^^'

It's good that you managed to get the turbo loaders/stackers working though! Can't wait to see them :)

[Regarding graphics]

Yeah photoshopping sprites is pretty much what I was planning to do. So far I've made these edits quickly...
I could make all the science packs like this. Maybe draw some new patterns on their top...?3

Other edits I was thinking of making were tungsten/holmium parts, refined concrete bricks (fun fact: "refined concrete" might be based on sulfur concrete, so making concrete bricks yellowish and with a slightly different shape might be enough), probably bacteria sprites too. Maybe other item sprites if you'd need.

I could attempt to model and render the items again aswell. But this will take longer, since I mostly have experience with CAD softwares (Solidworks, Onshape...), not sculpting softwares (Blender).
