Title: Cloner/Formula effector change shading
Post by: LeSill on 2023-07-31, 17:41:46
Hi guys,

Applying the effector formule to a cloner causes me problems. Each clone was to be rotated 180 degrees. With every subsequent clone, Corona changes color/shading. Any ideas as to why this is occurring?

Kind regards

Hi there,

A few questions if I may? ;) Can you try this with a standard c4d material? Are you certain it's a Corona issue? Have you considered using the Corona mapping randomizer for this?

Hi,

I have made a test with C4D material and it works well. The problem is probably related to the Corona material. I will test the randomizer as well. Anyway it would be good to solve the problem with Corona material.

Hi there, are you able to share a test scene for us so we can look into it further? If so, please use the link in my signature below. :)

When I click on the link UPLOAD and try that I get message "The person you are attempting to send files to is not eligible for this feature."

Uploading these days is done through ticket, so that's the "Contact Us" link then you can attach any files needed (there is no separate uploader any more). As a note, worth including the link to this forum thread in the description of the ticket :)

I've noticed a similar issue. I merely used cloner, transformed it to an editable object, and then made UV. The same/similar issue occurred. Take a look at the pictures. The first is with basic C4D material. This is somewhat bothersome because I need to submit the proposal very soon.

I HAVE noticed a bit later, that it was caused by the normal map with LINEAR gama. When I uase a normal map with gama 2.2 the problem was gone. ARE WE SUPPOSED TO USE GAMA 1 FOR A NORMAL MAP?

Hi there @LeSill,
I've replied to the support ticket you submitted.
Looking forward to hearing from you.
