Title: What would be reflect map over here?
Post by: GraceKellyPerfect on 2021-07-14, 23:52:27
Hello, new user here. I m downloading one material from quixel megascans but don't know what represents reflect map on their downlaod list (picture attached)?
Normally when I use Corona I only use bitmaps for diffuse/albedo, reflect, gloss, normal and displacement. Their download list is either missing reflect map or is it called something else over there?

I've generally found that the best place to start is by using the Quixel Bridge 'Export to 3DS Max' - and then tweaking the material if needed after that.

This only currently supports the Corona Legacy material, but hopefully there will be a route to Physical Material after the full release of Corona v7.

In answer to your specific question, the exporter usually puts nothing in the Reflect slot, Glossiness to Glossiness and sometimes the Specular map to the Fresnel IOR through a series of corrections...

Cavity map. Although not always necessary.

That would be a specular map but it needs some treatment in order to be used for IOR, I would suggest using their bridge plugin it does a pretty good job converting their presets into Corona legacy material. If you are considering on using CoronaPhysical then the entire process is much easier with a single roughness map or Spec to IOR mode.  If you require any further assistance on this please don't hesitate asking.
