Build in render engine made great improvements but still could use some further work to get more usable.
Real lights:
only hdri based lighting works for basic quick renderings but is not sufficient for the need of a CG professional.
i mix hdri ibl and lights always together
With lights I can set reflections and contrasts etc in away not possible with lazy ibl workflows 😉
Often only one to two lights are needed
Camera position:
For designing shots and later revise them after model changes it is useful to be able to jump back to previously used camera positions.
Render speed:
even with only hdri and transparent backgrounds render speed is relatively slow.
Thea render got licensed by solidThinking and the engine blasts key shot in terms of speed.
online rendering can help here speed wise but this costs money and is time wise not efficient
