Re: [Flightgear-devel] Random Buildings improvements - phase 1
I've just checked in a change so the buildings now use the Effects system properly, which includes a global cache of the textures. This might help. Nice - have to try this. Btw - could you take a look at the ambient value of the material declaration? I have the feeling it is very low, I'm getting very black shadows for low sun, much more than for the typical static building. * 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.

It is configurable in the data/Effects/buidling.eff file under parameters/material/ambient if you want to have a look yourself. I'm happy to accept a change to the value - I haven't spent any time tuning it. -Stuart -- 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.

I think it should be in the range 0.7-1 - our ambient light is about half of the diffuse light (0.5, 0.5, 0.5) vs (1,1,1) - if the material declares ambient to 0.3, you get shadows which are then 0.15 times the base color - which is way too dark as compared with how terrain or most of the models are shaded in indirect light.

James Turner - I'd be very interested if this change improves your framerates. Sadly no (I already tried 3 to 2 and 10 to 2 - the number of drawables and primitive sets drops, but that's clearly not the bottleneck in this case). So I still go from 50fps to 33ish over EGPH with density = 1 not great (but flyable) One thing I did notice - you're creating a state set for each bin, based on texture. I think you want to globally cache those by texture (all the other parameters are fixed anyway, right?), so that OSG can see that all the prim-sets in different bins share a state set, and hence reduce state changes.
