Title: Fabric Material Playground!
Post by: maru on 2025-08-25, 17:08:18: We’ve added something exciting in the latest Corona 14 ~~Daily~~Preview — the Corona Fabric Material!
It’s designed to make creating woven textiles easier and more realistic than ever, giving you physically-accurate shading for all kinds of materials.

Think clothes, blankets, and bedsheets — but also wicker baskets, woven bamboo, ropes, translucent lampshades, and more. Basically, if it’s woven, this material can help bring it to life.

At first glance, the parameters might feel like a lot, but don’t worry — we’ve put together a handy guide with clear explanations and examples to get you started:

We’d love to see what you create with it — so go ahead, experiment, and share your results!

I guess that would be a pretty niche use case, so please log it in the Ideas Portal. :)

Did you make a typo here? ;]

Looking forward for C4D preview...

Post by: maru on 2025-08-26, 18:31:03: Some more shenanigans. To get this effect, you first need to downscale your bitmap to the "resolution" of the fabric. For example, if you are using 100x100 wefts x warps, then your bitmap has to be 100x100px. It's best to use nearest neighbor filtering when downscaling. Additionally, once you load your bitmap as Corona Bitmap, set its filtering to nearest neighbor too. Optionally play with mapping to center your logo/texture and disable tiling. I also masked the logo with a procedural checker map to get interlacing.
