Hy there.
Now the solar panel is nice and can be set up ingame to go from 1x to 5x.
Now we need an Accumulator wich can go from 1x to 5x also

I say this so we dont build 10 Solar Panels and 50 accumulators.
Also it should have different recipe for each setting, for Accumulator and Solar Matrix:
1x = 1x resources cost,
2x = 2x resources cost,
3x = 3x resources cost,
4x = 4x resources cost,
5x = 5x resources cost,

Make it normal at 1st then use ur magic and make it special like the solar matrix after with good graphics :D

I like the recipe idea, i would prob make it another setting and not force it to scale with production though

What about the Acumulator ?

It could be fun to make one, I prefer to make the graphics first as thats what I enjoy most about modding, so its just a case of having inspiration

I would not use that at all, the whole point of creating the art is to make it from scratch as its the making it and designing it that is fun. using that 3d model would rob me of the journey and suck all the enjoyment out, also if I were to make one it would not look like the stock one though I would use elements of it to guide/inspire a new design
