Just some subtle lights and a Vinaigrette dressing, yummy. Looks good with a 2d light on the portal. I can’t think of one portal that should ve shiny.
Looks very cool, maybe some effekt behind the portal, so the hero is stepping into the portal without standing begind it before teleporting.
That is a good idea.
A little particle effect when he enters the portal and stop all movement when not visible as if he has already left this dimension
Two choices, disable render momentarily or disable movement.
