is this an 8-bit, 16-bit issue?

Read about it a little bit here

Bump map looks ok on phong material, has stair step effect on physical material - Questions - three.js forum (threejs.org)

Hi,
Could you share a link to a scene with this effect (either here or via private message)?
I will take a look and see if there is anything that can be done about it.

Indeed the problem would be resolved if 16-bit texture would be used for the bump map. But unfortunately currently we don’t support such textures.

We could also do a more advanced filtering of the bump map, but it would be very costly.

I’m wondering if using a normal map would work for you in that case? We are considering adding support for normal maps (maybe even in the next release).

Maybe to have these features as options, which u can maybe turn on and off, but with a warning about scene size/tax, like I need the quality Bump/Normal for only 1-3 materials only, looking forward to Normal maps :D.

In the cloud editor, normal maps should be working now.
We are planning to release them in the desktop app next week.
