Is there a solution for double-hung windows?

OMG - you are a genius! Thank you!!!!!

Ted,

Here's the packed scene - thanks for the tip!

Ted,

I've exported VRMesh from 3DS Max, loaded the VRMessh into SketchUp, and used the Vray material editor to re-map or, as with your Oak leaves, import the materials. In addition, I've erased all of the VRMesh geometry and replaced it with a 2D always-face-camera image of the model. The tree file is apparently too large to attach to this post (15MB). Thanks for your help!!!

Here's the result using the Oak leaves shared by Ted. What the heck?

I would suggest not using refraction at all but rather a V-Ray two sided material instead. Two sided materials allow for light transmission with out having to use opacity settings or refraction settings.

Take a look at the leaf material I've attached here and test it out in a sample scene. I think using a material like this will give you the desired results.

Thanks Ted! I'll give it a shot and report back!

Thanks for the thoughts and suggestions for things to look into. I haven't gotten the issue resolved, yet. See this image for a close up of the phenomenon.

I was initially concerned that the issue had to do with materials not being mapped on both sides of surfaces, and it may be just that, but I have no idea how to map materials on specific sides of a VRMesh.

Hi everyone - this is my first post after many months of reading the excellent posts here!

I'm posting because I cannot figure out what's going on with this one particular tree type! It seems that the edges are almost transparent.

Here's the back story:

Exported tree model as VRMesh in 3ds Max
Imported VRMesh into Sketchup and re-mapped materials

I have experimented with refraction and transparency/alpha to no avail.

I'm using SketchUp 2013 Pro and Vray 2.0.

See image of straight rendering. You can see the issue at the top where the white background is showing through the leaves. Looks like fog, but there is no fog (multiplier set to 0 in refraction layer for leaf material).

Please help!!!
