I just put together a 1.10.2 pack the second time and am running into the same issue as always: As soon as it hits ModelLoader: baking .... (see picture below) it will slow down until it stops responding.
At one point, aprox 10 minutes later, it will just run out of memory. Used the Curse launcher to put the pack together and the legacy mc launcher to start it.
Not sure if this is an issue with forge and the right place to ask but I hope someone already experienced or saw such an issue.
