Here's the texture atlas of a very large pack (HermitPack).

As you can see, Blood Magic takes up a large amount of space.

Here's the new mod to dump textures if you want to try it out: https://github.com/mezz/TextureDump

Another example with All the mods 9

@WayofTime Is it possible to add your own atlas for the mod?

I am maybe going to rewrite the routing nodes in JSON and compress some UVs. :)
Also, would it be that bad to render the Table / other models in TESR @WayofTime / @TehNut?

I talked to mezz about this last night and knew he was going to submit the issue. I will replace the image with one from just Blood Magic when I get home tonight.

@Yulife It would be bad, yes. TESR's should only be used in the case of animations. The Altar probably doesn't need one, tbh. In fact, I'm 90% sure it could be done completely in the Blockstate using a submodel.

Just an FYI, some of the other things in that image you posted aren't from the mod (such as the big textures that aren't the alchemy table). Not sure which mod those are from. Posted are the big ones I'm actually responsible for: http://imgur.com/a/EOw44

@Yulife I do not want to move .json models to TESR. They redraw every tick.

Thanks, I mistook those for being from BloodMagic because of the ones nearby. The new TextureDump mod gives information about the textures (you can hover over them to see details) and I found that they are mostly from Mekanism so I'll report there too.

Looking at it all routing nodes could become two 16x16
