I want to make a car tire shader however, I am banging my head on how to make it more procedural. I want to drive sidewall via the vertex map and dirt on the main surface via another vertex map How do you set up vertex maps in corona c4d Ideally, I want to be as procedural as possible so I can reuse it on different tires. I made one for octane but struggling for Corona any ideas/recommendations or examples I could follow? Thank you ---

Take a note: Always show your current W.I.P along with visual references of your intentional goal and, if possible provide your “look-dev” scene. Otherwise we’re all wasting time with guessing… and merely expressing personal opinions. Also, check “Cosmos” library and other resources… e.g. [https://www.corona-materials.de/en/material-library/-](https://www.corona-materials.de/en/material-library/-) ---

Basically here is what I did in Octane some time ago. Basically, the idea is to make the same in Corona. I have piped in a ton of different noise maps to generate various different layers of dirt and linked gradients to them to have variation in dirt Currently, in corona I have bog standard tire material with nothing fancy attached image ![12312312.JPG](https://europe1.discourse-cdn.com/chaosprd/original/3X/1/7/17b7100bf9fdc5dd92386143a6844c4d3cbd8f5c.jpeg) ![123312231.JPG](https://europe1.discourse-cdn.com/chaosprd/original/3X/a/7/a74906073c31ebaec86bb8b29e3c797391168d45.jpeg) ![Default.JPG](https://europe1.discourse-cdn.com/chaosprd/original/3X/6/7/6798989b254b04dcf84d24b7a81d23db17046811.jpeg) ---

I was hoping to avoid doing that with decals but looks like it will be he way
