(The text animation assumes that setting all of emissive/ambient/diffuse/specular works on an osgText, and it no longer does - for some cases we could map the emissive color to the text color, but this would break some other cases…. and text still won’t receive normal lighting in that case)<ref>https://sourceforge.net/p/flightgear/mailman/message/36703340/</ref> | (The text animation assumes that setting all of emissive/ambient/diffuse/specular works on an osgText, and it no longer does - for some cases we could map the emissive color to the text color, but this would break some other cases…. and text still won’t receive normal lighting in that case)<ref>https://sourceforge.net/p/flightgear/mailman/message/36703340/</ref> | ||

{{Note|As a workaround, using a canvas for this is actually not that bad - it eats some memory equal to the size of the canvas (so make it as small as possible) but in terms of performance, it will end up about the same. <ref>https://sourceforge.net/p/flightgear/mailman/message/36113197/</ref> To be clear it’s 100% a bug that can be fixed, just that given the effort to fix it, I’d recommend going with the canvas solution instead.<ref>https://sourceforge.net/p/flightgear/mailman/message/36113508/</ref> }} | |||
The osgText is probably (or at least, possibly, there’s a few other options besides) being ignored by the effect system, this is fixable but fairly unpleasant work. <ref>https://sourceforge.net/p/flightgear/mailman/message/36113197/</ref> | |||
Back in 2017, the issue seemed that we now set a shader program on the font state-set, which is tripping up something (the effects system or otherwise), but we need to investigate further to fix anything. <ref>https://sourceforge.net/p/flightgear/mailman/message/36141064/</ref> | |||
James tested current OSG (3.7.x) and we still have the same issue to fix on our side. | James tested current OSG (3.7.x) and we still have the same issue to fix on our side. | ||
