Need Assistance: Materials Not Showing Up in Rendered Mode?

Hi, I’ve added material to specific parts of my 3D model but for some reason when I have them in rendered view it does not show up. It only shows up when I do actually render the image, but not in the viewport. I am trying to render something as colored glass, but it only shows its color after I render it but not in the rendered viewport itself. Is there a way I can work in render mode and still see these colored window effects and not have to render an image everytime I want to see how something looks?


Hi there.

May be useful to show a screenshot example and your SystemInfo.

and attatched are screenshots of my issue colored glass effect can only be seen once i actually render the image, but in viewport render mode it doesn’t show. appreciate any and all help! :slight_smile:

Rendered mode doesn’t do well with transparent materials like glass. Raytraced will be better, as it uses the same engine as Rhino Render.

Ahhh, okay thanks I’ll try this. My only concern is that I will have to eventually use grasshopper to animate the geometry. Do you think that it will be a concern?

To be honest I don’t know what the state is of creating animations through Grasshopper and render them out with Raytraced or Rhino Render. Maybe @Japhy knows more about that.

No worries, thanks for your help so far! Trying out raytraced view and I can see the colored glass now…just taking a while to render. Hopefully it works out when it comes to using grasshopper. Thank you!

That’s a reasonable amount of individual glass to raytrace. Your 3050Ti mobile will take a while to process that, being a mobile solution with lower numbers of CUDA cores and OptiX RT accelerators.

Hi @Stella_Gonzales
If you are looking to make a material that works better than the built-in glass for the rendered viewport, try making a PBR material with opacity around 40-50 and the specularity F0 turned all the way up to 1 - see screen grab for reference. It will, on the other hand, not render correctly in raytraced AT ALL! So this is solely for the rendered viewport.

HTH, Jakob

Hi Jakob,

Will definitely try this out! Thanks for the tip!

Also, keep your drivers up to date. Though mostly its small, sometimes they actually make good differences in speed. Your current Nvidia drivers are from last year.
