ok, just for testing I did change only some of the file names:
from:
enriched_sunnarium.json
iridium_ingot.json
sunnarium.json
to:
Enriched_Sunnarium.json
Iridium_ingot.json
Sunnarium.json
This did not change anything. Changing the folder name from "crafting" to "CRAFTING" did also change nothing. More interesting is, that there are no forge warnings about missing textures in ALL my tested jars.
edit:
Some of the recipes are a bit strange.
1x Ultimate SP -> 8x Hybrid SP?
8x Hybrid SP + Adv. Circuit -> Ultimate SP ?
1 Adv. Solar + Stuff -> Ultimate SP ?
A real recipe chain without a back conversion would be easier. The main problem is, that you can specify cool new configs, but you may need to stay at the upgrade ratio of 8 for EU production.
Otherwise people may convert the solars back to more outcome at the end.
Example? I don't like massivly overpowered power generation:
solars {
I:AdvancedSPGenDay=8
I:AdvancedSPGenNight=1
I:AdvancedSPStorage=32000
I:AdvancedSPTier=1
I:HybrydSPGenDay=32
I:HybrydSPGenNight=4
I:HybrydSPStorage=100000
I:HybrydSPTier=2
I:UltimateHSPGenDay=128
I:UltimateHSPGenNight=16
I:UltimateHSPStorage=1000000
I:UltimateHSPTier=2
I:QuantumSPGenDay=128
I:QuantumSPGenNight=128
I:QuantumSPStorage=10000000
I:QuantumSPTier=2
}
Now, with the current recipes I would build one Adv. Solar Panel, then build one Ultimate from the Adv. one. After that simply convert the Ultimate back to 8 hybrids.
So, maybe the recipes need some work there. I may use Minetweaker to adjust the recipes, but other may no do that.
