Viewport refresh

I just installed instaMAT and have been testing it. I have the following problem: when I modify something in the layers or add a new one, the content of the viewer is not updated. It only does it when I change the seed.
I don’t know if I have to configure the software in any way.
My laptop has Windows 11 and an nvivia geforce 3050Ti video card. I have 32Gb of RAM and a 12th Gen Intel(R) Core™ i7-12700H 2.70 GHz processor.
I appreciate your help in advance.
A cordial greeting.

Welcome to the community @jmm00114 !

Does the viewport update correctly when you preview materials?
Is it possible that you have the render lock enabled?

If the lock is enabled, InstaMAT is now allowed to render.

Thank you! :partying_face:
It would be nice to have the lock icon red when locked. I’ve spent almost half an hour trying to figure out why the viewport isn’t updating, and it wasn’t evident immediately, even with the illustrated answer. However, I’m just passing through my first Atom/Elements tutorial, so that’s probably normal to be confused by the small things.
