In the most recent FFF the new proposed system is effectively turning the entire pipe network into single pipe segments connected with junctions. This is an improvement in theory, but it mentions junctions would be a little more CPU intensive...and then it shows the last image: https://eu1.factorio....

Just in case it's relevant, graphics settings: https://i.imgur.com/GqWVhcY.png

I assume this only happens with high graphics (double res), and is additionally only there in specific orientations. The problem is a lot harder to see at other zoom levels, except for 0.5x where it is exacerbated. I can see it in fast splitters facing right and down, but not left and up. When looki...

Note: I am not actually reporting a bug, but since this is where performance problems go, I figured this is the best place. I have a 350MB save where I explored 125k tiles to the right, and it takes a long time to load/save as expected. I've decided to offer it as an optimisation target, to see if e...

Currently it's a little inconsistent, it will show 3 s.f. if the abbreviation needs 100s and will show 2 s.f. otherwise. This is what it currently looks like: https://i.imgur.com/Tq4Vnoi.png "1.0k" "10k" "100k" In order to squeeze enough space for this extra digit (since the decimal eats valuable re...

Re-suggesting this in light of FFF #248, and also since there's no clean way to do this with the entities available. Right now if I want to implement a burner generator in modded I have to create the following: - A water generator - A steam engine - If I want a burn result, an extra entity to extrac...

In light of the announced 0.17 science pack tech nodes (for clarity to new players), I have a proposal to go with it for 0.17: - Production and high-tech packs are made cheaper - Techs that currently require prod/ht packs become more expensive to compensate; alternatively, make blue packs more expen...

We might also make an option to use lower-res sprites for shadows. And last but not least lot of shadow sprites could be cropped more because they contain also parts that is always occluded by machine that is casting the shadow. Honestly, for shadows, you could probably get away with something like...

There's a few annoying cases inside the tech tree that I would like to be resolved: - Advanced material processing 2 is not required, directly or indirectly, by tech that needs the production pack unlocked by it - Portable solar don't require the solar panel tech, same issue as above - Energy shield...

When adding drain to accumulators via a mod, it is added to the accumulator but does not always drain power. It appears to only drain power when not connected to a network. A bare-bones mod is attached for reproducing the problem. The only thing it does is give accumulators 5kW drain. Steps to repro...

Max zoom in amount should be 2x since HD graphics will be 1:1 at that scale, instead of 3.281x that is currently allowable. Alternatively, 4x would work, but you'd need a massive resolution to even benefit from anything beyond 2x. Here's some examples of the same area: 3.281x: https://i.imgur.com/XM...

Issue persists in 0.16.2. https://mods.factorio.com/mods/Hexicube/Hexi_Inline_Ore_Processing Steps to reproduce: - Place a liquidator and provide crushed ore via an inserter as well as sulfuric acid, but do not extract the output. - Note: A separate issue surfaces if you place the inserter first; Th...

A relatively simple change for new players. If the assembler has enough in all outputs to cause inserters to not want to add more items, the output slots should tint yellow. If any outputs are full, those slots should tint red instead.

Thanks for the report. This is unfortunately a limitation of the game as it is currently. An entity can't have 2 output inventories that inserters will grab from meaning the boiler which already has the main fuel as output can't also have the burnt result output. I've yet to see an effective design...

There's a number of different things going on with assemblers and rotations, which become exposed when an attempt is made to create non-square ones: The selection box never rotates The collision box always rotates The north sprite is always used for creating new assemblers without always-visible flu...

The burnt item slot on boiler entities cannot be emptied via inserters, which results in such a boiler eventually backing up and stopping entirely since no other method for automating this currently exists. Fuel items provided to the boiler can still be extracted via inserters. A mod is attached whi...

Issue still exists on 0.15.35.

TL;DR Uranium ore processing and red rocks should not have a random component, instead they should have a fixed yield. What ? Both uranium centrifuges (ore processing) and one type of red rocks have a random element to them. The centrifuge sometimes spits out U235, and the rocks give 25-50 stone+co...

PNG and JPEG support storing arbitrary data, and additionally has support for text stored with deflate compression. PNG's method: https://www.w3.org/TR/PNG/#11zTXt (iTXt could also work, storing the already-compressed string) I'd like to be able to directly drag an image of a blueprint into Factorio...

I've only noticed this issue on the Railway and Portable Solar Panel techs, and is not there for Logistics Robotics (which also has 3 follow-up techs).

As shown, the central follow-up tech icon has the connecting line shift 1 pixel to the left.
