FSWC's back in progress!

[Flying Mouse]

I tested the file you posted, works fine on my system  ;)

[Ashton Lawson]

Hey guys,

Okay, these'll be my last comparison shots for a month, since I'll be working hard on the main program code.

[Ashton Lawson]

Hey guys, this is gonna sound silly, but I just found out we can change shaders during runtime.

Don't kill me...

[J.]

love the rig shot, water fits in really well with the situation!

so if you can change shader while in game, would it be possible to make the water stormy if a storm started?

[pwheeler]

Hi guys,

just to let you know the eye op went well. Still having a bit of trouble looking at a monitor and its still a bit sore.

I'll probably be able to get back into things in a day or two.

Speak soon,

Paul

P.S. interface is looking great!!!

1. you are alive
2. you can see
3. you are healing

Thats great to hear!

if u mean seamlessly, like the program detects it the slowly blends into stormy-type water, no.

the only advantage is, u can pause, switch to another profile, or preset, apply, then when u go back to the game, the setttings have changed.  that's the best we can do at the moment.

having that done automatically would take a plugin for FSX, and I dunno how to do that.  yet...

lol, that was funny.

get well soon paul, we'll be glad to have you back .

ive got some kinks to work out of the interface, but otherwise all is fine.  in fact, the only kink i can think of is the combo box button not changing the status label at the bottom.

but still, im' working on registry key detection and stuff, so this program should be able to work standalone.

i'm also going to add a tree view type folder explorer, in case the program can't find the fsx registry key, or the registry key being wrong or something.

instead of plus and minus signs, or arrows on the tree view, i'll replace the vista-styled arrows with airplanes, lol.

but first things first, registry stuff.  annoying, but essential..

[pwheeler]

Hi guys,

In my half blind state I've done a few comparison shots with FSWC and default. These are around Seattle to tie in with Ashtons'.

Shader settings in use - fresnMin 0.03 - FresnMax 0.4 - frdot to the power of seven - colorbase * 1.8 - no moonglow - sun specular * 0.5

FSX with Acceleration, FEX, GEX, UTX

Hope you like...

[Ashton Lawson]

already replied to the screenie thread in FSW, but still, great shots.

Another thing, I'm curious about this colour multiple thing, is it what you've added or something?  I can't find mine (copied pasted from Nick's latest config after a request).

And your eyes can take the scenery, that's great.  Soon, (or maybe even already) you'll be back up to speed.

[J.]

good stuff, could you post your entire .fxh file please paul in a code box, beacuse those looks ace!

loved the way on sunrise/sunset shots, the suns reflections isnt a solid block, you can see the water riplling through it

good stuff

[Ashton Lawson]

yeah, sun reflections are good.

It's just a shame that the terrain doesn't cast any real shadows.

Hi guys,

glad you like the shots.

I use the 'medium mediterrainian' wave animation in FEX with my own custom water and sky textures.

It is a shame about the terrain not casting shadows onto the water. It does cast shadows onto itself though. I wonder why this is...


Paul

[pwheeler]

By thw way, how do you get FSX to change the shader while its running Ashton? I tried but couldn't figure it out.

Do you realise that this may mean that the settings could be tied in with a weather engine... e.g. reduce reflections when its windy...

Well, if you normally have terrain texture res set to 60cm, it'll be regular.
