🌈circular rainbow🌈 (challenge : light model)

3D ModelNoAI

This model is the same that https://sketchfab.com/3d-models/rainbow-challenge-light-model-3d4dedc95b744adb8b35b158ec2d6fc8

just a few changes on 3D Settings from Sketchfab

This is a very light model ( only one triangle, the obj. file has 27 characters ) sufficient to create a rainbow with visual effects that are applied from Post-Processing Filters in Sketchfab.

There are no texture, no light and no chromatic aberration.

So, will you be able to make the same rainbow without texture , light and chromatic aberration ?
