I was wondering if there is a way to change whole block model on condition. For example, if a chain block is standing on magma, the model is changed to some other model where the chain is looking molten and stuff but on other blocks, the model is the same.

I've found info on Wiki on connecting textures based on blocks around but can it be done with models as I described above?
If it's not possible right now, then this is my feature request!

I was thinking of something like this in terms of code:

{
"loader": "fusion:model",
"type": "connecting",
"connections": [
{
"hot": {
"type": "match_block",
"block": "magma_block"
}
"cold": {
"type": "match_block",
"block": "ice"
}
}
],
"models": {
"hot": "chain_tall",
"cold": "chain_cold"
}
}
