OTOY Forums

Hi.
I really love using Octane. Achieving realistic result is faster with Octane than with any other renderer.
But I'm always facing the same issue : turbulence scale / power limits.
The typical example is the simulation of plastic body noisy bump.
I prefer to use a tiny bump on reflection to achieve the best looking reflection diffusion on plastics.
The issue is that when I use real scale models, I'm always working with turbulence scales at 0.002 or 0.001 .
The same issue applies to the bumps power, but I can use the multiply map to reach lower values like 0.0005 .
Unfortunately, I found no way to divide the scale:

Hey cmatias,
try this and tell me if it helps.

Damn ! You save my day Lixai !
Entering smaller values with the keyboard now work as expected. I'm a long time 3dsmax user, but never thought about this setting.

Thank you very much Lixai.

glad to be able to help
now go back to work

This decimal issue has been there from the beginning.
Most of 3dsmax values are above 0
It´s much quicker to enter numbers above 0 than entering decimals!

Why not scale the octane values by 100x or 1000x?

since we work most of the time in cm, spinner precision needs to be 1-2 decimals maximum.
If we extend precision to 4 decimals this can become very unhandy for most other things......

That is also my point of view.
