Hey all, I'm currently doing my first "photomatch" job in corona render, previously i used to be a v-ray guy for this sort of stuff.
I find the coronashadowcatcher almost unusable, the rendering times are absolutely atrocious.
-I'm using perspective match on top of a photo to get the persepctive right.
-Then I'm putting the photo into this  material tree and applying to my geometry.
- I made sure to override the direct visibility to black, as mentioned in the shadowcatcher
- The initial render pass takes forever, 10+ min and rendering is then extremely slow
- Corona tonemapcontrol doesn't do much to the rendering time. I've tried bypassing it.
