Scott Davidson replied to Justin Desilva's discussion Seamless Texture Patterns"This is actually a tough mapping to solve. I use Rhino 5 and many of the new mapping tools. The process has many steps. But, from I can tell, this is the best we can do.
Here are the steps I take:
1) We will use a Custom Mapping…"
Justin Desilva posted a discussionSeamless Texture Patterns
I am trying to create seamless texture patterns on forms with rounded edges. When doing so, the pattern does not look seamless on the rounded edge unless I move the objects in Rhino. Shown above, you can see the original object (bottom) and shifted object (top). The top shape has the same pattern applied, but looks more seamless…See More

Scott Davidson replied to Justin Desilva's discussion How to render aluminum texture"There are many ways to go at this. I agree with Laurent, using even slightly curved surfaces makes a big difference.
Here is a quick try for me.
I used a metal with low sharpness (0.23) and high intensity (0.89). I also used a…"

Justin Desilva posted a discussionHow to render aluminum texture
Hi Everyone, I'm trying to render a painted aluminum texture, similar to the previous generation apple macbooks. Shown below are some iterations I've developed but they don't quite have that aluminum feel. I've noticed that aluminum itself should have high contrast, and show slight definition of form, without hard edges. Does anyone have any advice?…See More
Justin Desilva replied to Justin Desilva's discussion Material texture transparency"Thanks Scott, >Flamingo nXt Control Panel>Environment Tab>Deselect >No Transparent Object Alpha (Located at Bottom)
Materials with transparencies now render using the background type or color.

Scott Davidson replied to Justin Desilva's discussion Material texture transparency"At the bottom of the environment tab there is a switch titled "No Transparent Object Alpha" Give that a try and see how it goes. It is possible the Alpha channel is dropping out the black."
Justin Desilva replied to Justin Desilva's discussion Material texture transparency"Yes, I'm using an HDRI for the sky. The current background color is set to white. Thanks for the suggestion but still no solution."
A Smith replied to Justin Desilva's discussion Material texture transparency"Are you using a HDRI for the white background?
My suggestion would be to go the the environment tab and change the background colour. Default is black, that may be it.(Click the long black bit and select white)
but thats may have been…"
Justin Desilva posted a discussionMaterial texture transparency
When rendering textured materials with a transparent mapping, the negative perforations are rendering as black, opposed to white. Only when an object is behind the texture will the texture render out correctly. If no material is located behind the mapping, the negative (perforations) will default to black. Is there a work around?…See More
Scott Davidson replied to Justin Desilva's discussion How to create default nXt lighting scheme"Currently you can use the disk icon to the right to save out a lighting scheme. You can use the icon of the folder next to it to read in a scheme previously saved. So you should be able to get your default from there.
You can save into a…"
Justin Desilva posted a discussionHow to create default nXt lighting scheme
I often use nXt to quickly render out snapshots. When doing so, I use a custom set of preferences and would like these to be the default when opening Rhino, or nXt control panel. How can I create a custom set of nXt options so they load each time Rhino opens?Does nXt offer an option, or must I save out a new set of default Rhino…See More
