[Flightgear-devel] 'Black model problem'
So far we had: start with skydome shader on and landmass set to 4: - models appear black and are not shaded properly Click on landmass slider without changing the value: - modelss jump to proper shading I've made one more observation: Do the above at noon. Then change to dawn - models remain stuck with bright daylight shading It seems to be a problem in passing parameters to the shader, apparently at least some of the parameters aren't updated by frame but only when specifically triggered. As to the underlying cause, I remain in the dark though... * Thorsten -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Using tied properties as uniforms? I don't think so, because the same parameters do get updated per frame just fine when shading the terrain. * Thorsten -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

That's actually how terminator-relative-position-m (the sun position for shader purposes) is done - see Environment/local-weather-rules.xml * Thorsten -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Flightgear-devel] 'Black model problem'
Sorry, was looking at the wrong shader. You don't assign the terminator to an uniform in the technique n=5 in the model-default.eff.

Re: [Flightgear-devel] 'Black model problem'
What I think happens, is that, without the detail option on, the same shaders are used for terrain and models (terrain-haze), thus they get the terminator assigned from the teerain-default.eff. Once you enable the detailed shading for the terrain, that uniform is no longer assigned, since in terrain-haze there's another technique active, assigning the property to the terminator uniform in the terrain-haze-detailed shader, thus the terminator value seen by the terrain-haze shader active on models remains at the last value it had. This would explain why the lighting gets fixed momentarily when you move the landmass slider back and forth. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
