 
 Using the identical process to set the belt_animation_set property as for transport belts, the loader, loader-1x1, and underground belt entities have the above visual issue.
For additional weirdness, in that flickering you'll notice splitter graphics...
I have a base layer and a tinted mask layer, e.g.:
Code: Select all
transport_belt_animation_set = {
            animation_set = {
                layers = {
                    -- Base
                    {
                        filename = reskins.bobs.directory.."/graphics/entity/logistics/transport-belt/transport-belt-1-base.png",
                        priority = "extra-high",
                        width = 64,
                        height = 64,
                        frame_count = 16,
                        direction_count = 20,
                        hr_version = {
                            filename = reskins.bobs.directory.."/graphics/entity/logistics/transport-belt/hr-transport-belt-1-base.png",
                            priority = "extra-high",
                            width = 128,
                            height = 128,
                            scale = 0.5,
                            frame_count = 16,
                            direction_count = 20
                        }
                    },
                    -- Mask
                    {
                        filename = reskins.bobs.directory.."/graphics/entity/logistics/transport-belt/transport-belt-1-mask.png",
                        priority = "extra-high",
                        width = 64,
                        height = 64,
                        frame_count = 16,
                        tint = tint,
                        direction_count = 20,
                        hr_version = {
                            filename = reskins.bobs.directory.."/graphics/entity/logistics/transport-belt/hr-transport-belt-1-mask.png",
                            priority = "extra-high",
                            width = 128,
                            height = 128,
                            scale = 0.5,
                            frame_count = 16,
                            tint = tint,
                            direction_count = 20
                        }
                    },
                }                
            }
        }Code: Select all
-- Apply belt set
    entity.belt_animation_set = reskins.bobs.transport_belt_animation_set(adjusted_tint, variant)I've attached the save, log, and the two mods that haven't been published to the mod portal yet.

I cannot successfully attach it to this post (22.5 MB too much?)
Edit: The reason I think it's a bug, is if I comment out one or the other layer, they work individually:
