Hi....try turning color to value and keep it at 0% and in your transparency put the orange color.....I think this will do it..I do not have Carrara open to try it.....but if it does not work....I will open up carrara and find the right way. kirk saavedra www.shaders3d.com

In the render room.. have you made sure that 'transparency' and 'light through transparency' are checked?...

This just all seems wrong to me...?
If i want the "color" of the item to be orange.. well then I should set "color" to orange?
If I set the Trans to a color... how do i adj "how" transparent the item is?... if trans is a "color" then how can I make it very clear? or adj it to something that is only slightly clear?
did that make sence?

Can you attach your .car file to a message? This is a curious challenge.

you also might try increasing your ray depth... with all those rays trying to bounce around in there, maybe none are getting back out

After taking a quick look again at your first post, you do have some orange showing up in it which makes me think it's not a shadow catcher deal. If you're comfortable with it, send me the file. -Kix

The problem is in everyones shader tree it shows the reflection way to high.....this will not look good....turn it down to 3%.....trust me the color goes into the transparency section...not the coler section...the color section gets a value...and that is where you control how much the pumkin will look transparent. thanks kirk

Kixum, about the 11%, I think the 'value' value of the color in the transparancy channel is above 90%, so it adds up to more then 100%. Which is forbidden by the laws of nature, if I understand correctly.

Right. If 10% of your light bounces off the object, then you have only 90% left to either be absorbed by the surface, or to continue through the surface by transparency. To use an extreme example, you can't have an object that's 100% transparent and 100% reflective. That would mean that all of the light is passing through and all of the light is also bouncing off. I was never a Ray Dream user, but I played with it years ago and it handled this issue nicely - if I remember correctly, reflection and transparency were handled with a single slider control with two little arrows, one for transparency and one for reflection, Since they couldn't pass each other on the slider, it was impossible to get the percentages to overlap unrealisticallly. If you wanted more transparency you'd have to reduce the reflectivity. It was slick. I'm sure many of you are more familiar with this feature of Ray Dream. Still, in a more-strict physical model I would think that absorption of light should be handled in the same way, but as I recall it wasn't. - Joe
