Thanks for the reply:
I sell my kidney(not) and bought a 3080 and the Electric Dream demo run 30fps 1080p. It’s super slow and make me wonder will future project really use that kind of technology? My guess to that answear is yes but in a version where it scale down a lot. The performance is a huge issue but I guess the UE dev are focus more on the feature set first, performance second.
Back to the topic on should people learn houdini, I dig around more and I guess Houdini is still the king of the VFX and important to the tech artist toolset.
