[Max] I need help! / CoronaPhysical Mtl & Physical Mtl Questions
« Last post by Jpjapers on Today at 17:21:21 »Recently ive been confused by a few things in the the Corona Physical Material that over the years ive learned to live with. Its possible im completely using the physical material incorrectly and im just used to the simplicity of the corona material.
A few questions;
1. Why does inverting a map in the bitmap node result in a different result than if i invert it within a corona colour correct node?
2. Why do the same PBR maps connected to both a corona physical material and an autodesk physical material render very differently to each other? Ive attached an example compariso_galv.jpg. On the left is a physical material, the right is a corona material.
3. Why do PBR maps appear different when rendered in corona vs the previews of the material? See the attached material preview from Poliigon and the render from corona comparison_galv.jpg
5. Physical Materials also appear to render faster than Corona Physical Materials or at the very least the gpu denoiser handles them much faster and much better. See passes comparison.jpg for both materials after 5 passes and the gpu denoiser has kicked in.
6. Finally, To get a similar result with metals in the physical material vs the corona physical material it appears that i need to connect the diffuse map to the base weight, base color and reflection color slot. Why? See attached passes comparison for the result of this and the material graphs.
Ive never really questioned these things before but just learned to live with them.
