New openBVE release–v1.0.6.0<\/span><\/strong><\/p>\n

A new version of openBVE is now available, version 1.0.6.0; head over to the \u00bb openBVE homepage \u00ab<\/a> to download the latest stable release. One of the three most noticeable improvements in this version (the other two being time acceleration<\/strong> and the ability to mute sound<\/strong>, more below) concerns the Smooth Transparency<\/strong> feature, which has been dramatically improved. If you’ve enabled this option in openBVE previously, you might have noticed that while the quality of the rendered scenes was much better with Smooth transparency enabled, occasionally, unsightly fringes appeared around some transparent textures, where translucent pixels were rendered. This was problem was also more pronounced on Cross-City South v1.4 due to the frequency with which texture transparency is used in the new scenery. This issue concerning texture transparency and the z-buffer is a complex topic which I gather not all OpenGL developers adequately address, however Michelle has found a way of solving the problem, and while the performance is a little lower than with the previous implementation (especially on routes where a very high number of polygons use texture colour transparency), the visual quality is far better, as the following comparison screenshots demonstrate (along with the new X-City South v1.4 screenshots below).<\/p>\n

On the left, we have the \u00bb ATS-Sn\/P Test route \u00ab<\/a> in openBVE v1.0.5.0; click the thumbnail and note the fringes around the catenary gantry texture. On the right, we have v1.0.6.0–no such issue can be observed, and the end result is superb:<\/p>\n\n\n\n
