Wish: disable all auto thumbnail updates of materials

Rendering
1

Hi,

it slow down to work with the material editor if every time all material thumbnails are regenerated. At the moment I’m fighting with the update of the “replace” function. A lot of object lost the connection to the V-Ray materials (by sending my scene file to a client and back to me) and every time I start “replace” than the replace UI open and start to recreate all thumbnails. It’s nearly not useable by the slow down. I wished I could work without thumbnails.

Here a screenshot of the UI with the slow down. Also I don’t understand the order at the left side.

I also find Material Editor UI slow and frustrating at times. I second your wish. There must be some performance optimizations done in that area.

I think this exists, at least for the material list, but as far as I have seen it has no effect

I personally find previews to be mainly eye candy and not very useful for actual work, and I don’t like the cpu getting hammered just to render them, so quite early on I added a preference in my plugin to disable rendering previews entirely, in which case they just get the “rendered” viewport (opengl) look, like you see before the render plugin is asked to render them

The problem gets much worse with the use of SBSAR materials, which can add literal minutes to simply scrolling through the materials tab - you scroll, suddenly it wants to update the materials thumbnails, so it bogs down, then you scroll some more, it bogs down again, and so on and so forth.

I only have 7 materials and the material panel becomes unusably slow. this is pretty crazy and I hope McNeel can solve it soon.

Some people in my office including myself thinks Rhino8 isn’t an improvement. Rhino7 seems to do a much better job.

would you please share with us how you did it? I also want to stop the thumbnail preview rendering

sorry if I was not clear, I meant that this is an option I added in our render plugin, I don’t know if it is something that exists yet in rhino itself

You can set the advanced option EnableRenderedPreview to false.

Hi Nathan, thanks for the reply.
Disabling totally helps a little bit but did not entirely solve the material tab issue.
It is very weird.
