Terri Brown Posted March 9, 2016 Report Share Posted March 9, 2016 Hi guys, I've just started experimenting with this great plugin, so I know I'm probably missing something obvious here, but I can't seem to create leaves that have different colours on their front and back (see image attached). I'm a vray user - used to using Vray2Sided Mats for leaf translucency. Is this a geometry issue or a material issue? Here is a basic test render & leaf mesh properties attached too. - as you can see I can't get the purple back to show. Thanks a mil, Terri Quote Link to comment Share on other sites More sharing options...
Eduard Posted March 9, 2016 Report Share Posted March 9, 2016 Hi Terri, To fully understand the problem, I need to see the structure of your material. I also need to look at the settings on the Chaos material ID window. To do this, click the Chaos mat ID button, shown in my screenshot... Thanks!

Terri Brown Posted March 10, 2016 Author Report Share Posted March 10, 2016 Hi Eduard, Thanks for the speedy reply. Settings attached. My materials are nothing fancy yet - mainly just a bitmap plugged into the diffuse slot plus a bit of reflection. Do you need me to expand the materials? Thanks for your help.

Eduard Posted March 10, 2016 Report Share Posted March 10, 2016 Hi Terri, Oh, sorry I didn't notice that you have enabled the 2-Sided leaves option at the bottom of the Leaves mesh settings. Turn off it please. Thanks! Quote Link to comment Share on other sites More sharing options...
Terri Brown Posted March 10, 2016 Author Report Share Posted March 10, 2016 I did have it turned off previously...it was the same result (just slightly more transluscent. I can try again... A question: In what situation would you turn on 2-sided? Thanks Quote Link to comment Share on other sites More sharing options...
Eduard Posted March 10, 2016 Report Share Posted March 10, 2016 A question: In what situation would you turn on 2-sided? It's mainly used for game engines. Someone of the customers requested us to add this option. If it's on, the system creates 2x polygons on the same vertices, but with different normals.

Terri Brown Posted March 10, 2016 Author Report Share Posted March 10, 2016 Ok great, thanks for clarifying. Here's the new test with 2-sided switched off. Not much difference I'm afraid. Quote Link to comment Share on other sites More sharing options...
Eduard Posted March 10, 2016 Report Share Posted March 10, 2016 Please send me your scene file, I hope it will be faster to understand and solve this problem... Thanks! Quote Link to comment Share on other sites More sharing options...
3DMK Posted March 14, 2016 Report Share Posted March 14, 2016 You need to use Vray 2-Sided Material to achieve this. Set the Translucency to black. Quote Link to comment Share on other sites More sharing options...
Terri Brown Posted March 15, 2016 Author Report Share Posted March 15, 2016 Ok Eduard, will do. What is your email address? @3DMK: I have already assigned a vray 2-sided Mat, but if I set the translucency to black how will I achieve the effect of translucency when light shines through the leaves?

Eduard Posted March 15, 2016 Report Share Posted March 15, 2016 Eduard here is the scene file... Thanks for the file! Your Back material was disabled in the Vray 2-Sided Material settings. Please see below: Turn it on for both materials leaf A and leaf B. Cheers Quote Link to comment Share on other sites More sharing options...
Terri Brown Posted March 16, 2016 Author Report Share Posted March 16, 2016 Awesome thanks. I also lowered the translucency to a darker grey (as suggested by 3DMK) and it's definitely looking better. There are some issues I need to fix with intersecting leaves and strange 'angle across' features, but other than that am quite happy for a first try. Thanks for the help!!

Eduard Posted March 16, 2016 Report Share Posted March 16, 2016 I configured a little bit your plant, you can see: 20160316_Roheo_GrowFX.max (max 2014) Cheers Quote Link to comment Share on other sites More sharing options...
Terri Brown Posted March 16, 2016 Author Report Share Posted March 16, 2016 Thanks Eduard but I can't open it - it seems you're working on a later version than me. Please save it as a 3DS Max 2014 model if possible. Thanks Quote Link to comment Share on other sites More sharing options...
Eduard Posted March 16, 2016 Report Share Posted March 16, 2016 Ok, I updated my previous post. Please try again. Thanks! Quote Link to comment Share on other sites More sharing options...
Terri Brown Posted March 16, 2016 Author Report Share Posted March 16, 2016 Awesome thanks. Having a look at it now. I also changed my paths and distributors to something similar after sending you my file - it works much better. And good to see use of the Object React modifier - I was using the Object Slice one instead This plugin is really fun. I think I prefer creating plants to architecture at the moment!
