[Max] Bug Reporting / Bump changes strength depending on pixel size of the object on screen
« on: 2021-10-06, 20:22:45 »
Software: 3ds max 2021, 2022, Cinema 4D R20 with Corona 6
Corona version: latest 6 version, and 7 version
Hi all, I recently started using Corona for 3ds max, and I've come across this strange behavior, maybe this is normal?
Bump changes intensity depending on the size of the object or resolution.
In my scene I have a sphere, 1 light, and a black material with reflection on and glossy at 1.0. + a bit of self-illumination texture to show the shape of the sphere
When I'm up close, dispersion of reflection is all over the place because of bump, but the more I zoom out it gets sharper and sharper, far out and it feels like there's no bump on the material at all, it's pure sharp reflection.
I've tested this with Max's Noise map, bump map in bitmap form, and normal map, but it's the same.
I've noticed this in Corona 6 and 7, and also noticed it in Corona for C4D. I've made a test in FStorm, V-Ray and Scanline, and there's no bump scaling/weakening due to object size on screen, dispersion of reflection on bump looks the same up close and far. Here are a few screenshot showing and comparing the effect in FStorm.
Vertical red line shows where the dispersion is visible in closeup, and that same line is marked on the same position on far version.
This is causing me a lot of trouble when I'm tweaking a material up close, and when I render a full resolution image, everything looks different.
I've attached my test scene in max 2022
Thank you for your answers
