Steel Grating

[gain-concern]

Hello everyone

I'm currently trying to create a grating in C4D.

When building the 3D model, I thought that I could create the grate using a material so that my file wouldn't be too heavy. That's why I built the grate in a simplified form as a cuboid. Unfortunately, the rust now only appears on the outer edges of the rectangle and does not become a grating as hoped.

Is it possible to create the grating using C4D and a material or do I have to build the grating directly in the 3D model?Bildschirmfoto 2023-11-21 um 10.27.59.pdf

Hi gain-conern,

The pdf is not uploaded. Have you tried to use a Bevel on your model?
Images, like screenshots, are best as jpg and below 500 pixels in height.

If you can, share a cube (to scale) of your model with the material you have so far. Any c4d file below 1MB will work here as an upload.

Cheers

Hello Dr. Sassi

In the attachment I am sending you two pictures for explanation.

Attached is the link to the grating in question:

Attached is the link to the perspective:

The file with the block and the material is also attached.

I am wondering whether it is possible to create a material that ultimately looks like this:

Hi gain-concern,

Perhaps use the RS Object Tag> Particles, with the MoGraph Matrix, to get these detailed results without any render bottleneck.

I have used a simple material, but the key is that the Noise is set to World like the Zink-coating would look with that Grating.

Render the scene, and you should notice how fast it is.

Two objects are available, beveled or simple.

As a side note:
My initial tip with Bevel was based on the guessing (missing the image) that it was perhaps based on the German term "Grat" (English Burr). Before I studied Architecture, I went to a Metal/Electric school, and in our practical assignments, we had to get the Grat (Burr) off the Steel edges. (entgraten).
Since I have gotten questions from all over the world in the past two decades, I often have to go with a guess. But yes, your term was absolutely correct.

All the best
