material preview quality

[marcatore]

Searching the forum I didn't find a thread about this.

My question is: is it possible to increase (or set by rendersettings) the quality of the material preview??

I found the preview isn't helping, at the moment, overall when you have a reflection/refraction glossiness.

Currently nowhere (only inside script actually).

Re: material preview quality

is it possibile to know where we can find the settings fo the material preview render??

In this way everyone could set the best settings related with CPU performance and needs.

Or add the preview render settings into the render global settings

Thanks in advance.

As I said you could edit the script. Its pretty easy to find preview sections in render.py

Or add the preview render settings into the render global settings

This is currently impossible.

Thank you. I'm not sure but I think that preview settings starts at line number 579 and finish at 603.
Is it right?

I've changed in this way but it seems it doesn't use this parameters

I've found good settings in quality/speed
