This is the same scene from my shadow catcher post, but Now I have different questions so here's a new thread. As you can see in this image, I have added all the cars on the left. The background image is from Google Street View (Street View Download 360 app). Just find a location and it gives you an equirectangular image. Good resolution too, 11835 x 6656, RGB (8 Bit). One thing is the background/shadow catcher image is very soft compared to the actual image file I'm using. Why is this?
The Honda CR-V's passenger door (middle vehicle) is supposed to be white. After much trial and error, I cannot get that material to look white and reflective. It's based on the blue material, but white. In this image, I have applied a chrome material to the rest of the car, as well as, the sphere on the road. The chrome material's Reflection tab has 999 in the Fresnel IOR and 1 in the Glossiness. I figured this extreme would surely give me a mirror look. Nope. Why am I getting that look even with chrome? There are no Post settings turned on. I even cooled the Corona Sun down to 5500k.
Another issue is the extreme hotspots on the front of the cars. No amount of passes or denoising smoothes this areas out. How can I fix these areas? If need be, I can simplify this scene and upload it, but right now its too large to post.
Thanks for any tips.
