Hi All,
I’m having trouble removing/changing the black lines/light reflections on this object to white ones.
I’ve tried changing some of the environment and material settings but I can’t seem to get it to ‘shine’ line it would in white light/sun light as I’m still a novice at this stuff.
Can anyone help please?
I’ve attached a screen shot.
Any help would be appreciated,
Ashley
It would be useful to see the actual file. But it looks like you have intersection of geometry here?
Check that there isn’t two of these lip-like objects in the same place.

Hi David,
I’ve reduced the file so it can now be attached. Just the lips pedant on this one.
It’s not duplicated in the same place. I did think that but that wasn’t it.
If you’re able to take a look at the file, I would really appreciate it.

Those dark spots are due to internal reflections. They bounce so much inside that at some point the limit is reached.
You can decrease that from happening by increasing the bounce count. You’ll have to do that until you don’t get the black spots anymore.
In the Rendering panel go to Rhino Render Advanced Settings, and bump the different bounces to some higher number. Here with the relevant bounce limits set to 256:
it looks like glossy is making the most impact, changing the others does not make much of a visual difference as far as i can tell.
also how does the maximum bounces work? does it sum up in relation to the settings underneath the max bounce? if i set all of them to 300 each (not sure what the max is) it will still only create 500?
If you set them all to 300 then in total there will be 300. Depends really on how the bounces split on each time.
Hi Nathan,
Thank you for this, really helpful.
I can’t seem to get the black lines to go with your suggested settings, and when I raise it to 500 and then to1000, instead of 300 - it remains the same.
Do you know of anything else I could try?
Also, your image seems to have a think line/shadow over the pendent - what is this?
And, the material on your image seems better/clearer/more reflective. Do I need to change other settings to achieve what you have?
I think what you’ve got is just about what I’m looking for.

I just added a box under the pendant to show that it is transmissive, in favor of the ground plane.
Those dark lines are probably due to reflections going on still. Maybe move the groundplane a tiny bit down, like 0.01 units.
Nathan - thank you! I now have this how I want it for my portfolio.
Ashley
Enjoy creating your portfolio!
I’m getting there with it, i hope!
Nathan - I have may have spoken too soon. I want to add all 4 views to the portfolio page.
The top view doesn’t seem to show the same reflections/environment as the other views - is this usual? I’ve never even thought of using the top images for a final presentation piece before.
So, I wondered if there is a way to make the top view have the same light/reflections/ as the other views.
I’ve added an image to show how is currently looks. Are you able to give advice on this also?
I’ve tried changing the environment/sun settings but it just goes really light and 2D.
Any help would be appreciated.

Not my expertise, but perhaps it would look better if you didn’t have it on the “floor”. I think many jewellery photos and renders have necklaces either mounted or “hanging” just off the floor. You should hopefully get the light through the whole of the material then. At the moment, it seems a little wasted, or muted, to use a better term.
@user1381 as @David53 suggests you could rotate the pendant instead so that in the perspective view you can almost view it from the front of the lips.
The Top/Bottom, Front/Back and Right/Left views are parallel projections, they won’t look the same as the perspective view. Of course additionally you are looking from different angles regardless of the projection, so things will look differently.
Thank you Nathan and @David53 - this worked. I really appreciate all of your support with this!
I have another issue with another render but I’ll start a new thread for that.
Thanks again.
Ashley
