I have been having a really hard time dealing with display modes and transparency materials in Rhino.
I want to be able to control the amount of transparency of my objects in Arctic mode, but it looks like no matter the settings the only options I got is: Transparent or not Transparent.
So this is Default Arctic. The cone has Default Material applied to it, but with 40% transparency.
How come 0% look exactly the same as 40%?!
Now this is with 41% transparency:
So an increase of 1% goes from fully opaque to fully transparent.
And this is with 85% transparency:
Meaning and increase of more than double the transparency (from 41%) has no noticeably change.
I can’t understand how this even gets past devs, but worse, released. Don’t devs check things?
I should be able to control the amount of transparency of my objects with this slider right? Or it just just some of those things that the user can configure but actually is not meant to? It is my understanding transparency is ‘supported’ in Arctic mode right? If this is what you guys mean by ‘supported’ it clearly is not…
I tried fiddling with Arctic shadow settings and I got even more confused.
This slider basically seems to control at which transparency percent objects are actually transparent. Which is already super confusing. Add to that the ‘Never cast shadows’ and ‘Always cast shadows’ key which does not correlate with what the slider controls, at least not with the effect one sees in the viewport.
-If I select ‘Always cast shadows’ my objects will never be transparent no matter their transparency percent set in the material, even when I set their transparency to 100%.
-If I select ‘Never cast shadows’ my objects will always be transparent not matter their transparency percent set in the material, except at 0%.
How is this consistent? If a 100% transparency objects has no actual transparency, it follows that a 0% object be transparent…
Now, when colors of material change, everything seems to just get upside down.
To do this, I simply change the ‘Color material usage’ setting to Rendering Material, from the default Custom.
First, having different colored materials should not have this drastic effect on transparency:
Default Arctic, rendering material, 40% transparency on cone. Red plaster on cubes
Default Arctic, rendering material, 40% transparency on cone. White plaster on cubes
So by just changing the color you get to see transparency.
Except, it has not shadows.
Now one will think, maybe if I set that Arctic setting to ‘always cast shadows’ I will get shadows in my object. But no… Its the reverse, you have to set it to ‘never cast shadows’ to get this:
No matter the counterintuitive logic behind it, both red results still look horrible. That is not how transparency is supposed to look.
And I can’t even control it. When I change the transparency percent of the cone, I just get less or more saturated red on the inside…
I am at a complete loss when it comes to transparency in Rhino materials. At least in Arctic mode.
