Issues With Rendering and Raytracing White Plastic Material

Hi All,

I’m having some issues when raytracing this object. When I render it (image white 1), it seems fine - although, I’d like to have the shadows on the inner parts of the extracted part of the white part of the pendant.

But, when I raytrace it, it just goes completely white. (image white 2)

I need to raytrace this for my portfolio, because the pendant will be added to 3 other pendants, which are glass effects and they need to be raytraced to be viewed properly.

Does anyone know if/how I can change the settings so this looks more life like when raytraced.

I tried to change the rendering settings to help adjust this but it changes nothing.

Can anyone help me with this?

Can you post the file?
In real life, there are no materials that are 100% white, so if you make your objects 100% white, it will bounce light infinitely, and by result wash out shadows.
Try making your whites RBG 240,240,240 max and then tune your lights to make the object appear white.

Apologies Gijs - here it is.

Something like this would be my suggested approach:

It looks like you have a geometry problem in your model, where you have tried to use FilletEdge, and it has caused all sorts of conflicts on the back faces.

It should be simple to fix. If you want to revisit these in the future, especially if you change renderer or want to 3D print you may find that this will cause problems.

Additionally, you can likely make some tweaks once you have correct base geometry that may help you on your quest to make portfolio renders.

Hi Gijs,

First, of all - this is amazing. Especially because you managed to put it together in about 2 seconds.

I don’t think it’s for this portfolio page. But, selfishly - I’m going to use it for the next one. And, I thank you so much for that.

For the issue on this thread, I changed the settings in the rendering panel because I had to add this object and 3 others, which were glass and the lighting you’ve given this didn’t work. But you were not to know that as I didn’t include them in the file attached. Overall, I was only able to get this right because of the info you and others have given on this thread and previous threads and I’m really grateful for that.

Thank you so much!

Hi David,

I was aware of this fillet error. It’s okay though as this side of the object isn’t going to be shown and it’s not being 3D printed, it’s gold and perspex only.

I really appreciate your support and concern though.

Thank you,

Ashley

actually it took me 20+ years

Totally Gijs. Like the Picasso napkin story.

I really do appreciate all of your support.

Best wishes,

Ashley
