<html><head><meta http-equiv="Content-Type" content="text/html charset=utf-8"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">I’d like to be able to control the default background alpha in gltransformation, in particular i’d like to emit textures with transparent backgrounds. I’d suggest adding a property to control the background alpha, and then replacing the alpha arg in the clear color call in gltransformation.c:600 with this property value. Is this something that would be generally useful?<div class=""><br class=""><div class="">
