Is Blender good with UE4 ?
Yes. You need to use unit scale 0.01 metric though for skeletal meshes to work properly.
If you need a good rig you can use UE4Tools: http://www.lluisgarcia.es/ue-tools-addon/
I use Blender exclusively when creating models for my UE4 projects. Blender can definitely do the job it just takes some tweaking to get everything in scale. I’m also only a one man show so the cheaper the better and Blender wins in that category.
Not yes but hell yes!
