What you would have to do is take the oil materilizer textures and resize them to the size of the HD textures then copy them into the HD texture image, in the same row and column they are in, in my mods texture file. I think that will work, it's really not a supported feature while it's just a placeholder texture.
Scooby-Do mystery solved. I discovered that somehow I pasted into the wrong row. As usual, another problem accounted for by user error.
Now, if I can just figure out why my redstone transport pipes are invisible...
3x more coolant compared to a fuel burning combustion engine.
It uses more EU.
Yes it is for batteries, currently you can only use Tier 1 batteries (RE and such). I have to ask the IC2 team what their stance is on using crystals in machines. The code supports it but none of their machines use the crystals directly; you have to have a MFE or MFSU.
Thanks, that's about what I thought. As for crystals, I know that the Advanced Miner that F4113nb34st did uses crystals - and it's one of the main mods I use. But for something like this, where a more widespread integration is desired and necessary, it would help to know what the "official" stance is.
