alphaThreshold, rendering issues Software: Away3D 4.x

_kihu, Jr. Member Posted: 01 February 2012 11:38 AM Total Posts: 43 Hey, I’m developing a project with loads of plants and trees on stage. Due to the known z-sorting problem with alphaBlending involved, I’m using the alphaThreshold property. Currently, it’s set to 0.35. The problem is, with alphaThreshold set higher (e.g. 0.5), many leaves are missing. On the other hand, with lower setting, the colors are different than original. See images below: original render: http://imgur.com/nhSpF Away3D render: http://imgur.com/sPq7a Notice the bright edges of the leaves in Away3D version. I was wondering if there’s a better way to render this kind of materials. Maybe some sort of alpha map or other material properties? cheers, kihu

I also had this problem, I created a new class that could ever disable the AlphaThreshold of texture, only DepthMap. `// Basic material.alphaThreshold = .5; material.alphaBlending = true; // Correct Render material.diffuseMethod.textureThreshold = false; // Away3D4 Version material.diffuseMethod.textureThreshold = true;` Only to the classe attached.
