Ok, @VertexMachine apologies I’m stressed, and as people asked me to stop promoting the plug-in…
I hope this ends the discussion in my case:
1.- Makes no sense at all to have a model in unreal that you can use random artists, the idea is to train the model in your own style
EXAMPLE: Imagine you are making a new Resident Evil and generations are Pokémon 
2.- Which artists? And don’t tell me Batman…
3.- Yes I’m training the model and I’m paying
- All training for metahumans is dreamahuman and is mine, I decided to paid for sets of pictures with models, results are better
Celebrities etc… no need to explain
- All training for assets is quixel, because is the default…
