Cloud Shadows Coming to FSX/FTX

Featured Replies

I forgot, there's people out there that are nay-sayers at every turn. Put your product out and let the public decide. Don't let people who have less acumen than you take your drive to deliver. It sounds like a great product and if you deliver, the market will reward you for it.

Ed,What product do you represent? IF you do work for an addon...then a full disclosure is in order!;)MannyPS: I actually concur with your overall premise of the potential problem you highlight!

Your suggesting we would release a product that will automatically conflict with any number of other addon's. Rest assured if that happened we would not continue the products development, because we are as much simmers as developers ourselves.In respect of how it is achieved and what parts of FSX would be effected using certain FEX/FTX features we will disclose this fully, and furthermore we will take full responsibility for supporting that code, as we have done for FEX.Regards,Chris

Lots of software won't reveal their algorithms and neither do they have to.

Chris, you guys need to be commended at FE. I have your product FEX and really enjoy it. One request: in addition to the clould shadows that would be excellent, could you tweak the FSX engine so we would no longer be plaqued by the BLURRIES.Thanks a Bunch for your efforts.Jim Allen

does the recent release of FTX Blue include cloud shadows? if so, can we see some screenshots please? thanks.

Chris,If a photo says 1,000 words, a video says a million words.Screenshots are passe.I would encourage you to show some video. Moving cloud shadows don't come across in a screenshot the way they would a video.I'm psyched that you've solved this problem. Should be a fantastic improvement in realism.

The FEX guys and the FTX guys are no longer in partnership hense FTX has no cloud shadows.Peter from FEX has hinted that their new ground texture addon that he just announced on FSW will have cloud shadows generated by their upcoming environment simulator (thats me reading beween the lines though).Paul

Hello Ben,sorry, FTX doesn't contain dynamic cloud shadows. The code to enable this feature was supposed to be provided through the integration with the FEX weather engine/environmental simulator: http://www.flightenvironment.com/ However, the direct cooperation between ORBX (FTX) and Aerosimulations (FEX) was ended a few months ago. The FEX weather/environmental engine hasn't been published yet and we don't know whether it will include cloud shadows. If it does, we also don't know whether that feature will be exclusive to ground textures Aerosimulations publishes itself or applicable to ground textures in general. Perhaps Chris or Peter will read this thread and can speak to that.For FS9 many of the more exciting add-ons didn't show up until late in the cycle. With FS11 at least two more years away there's still hope that one day we will have at least the beginnings of dynamic cloud shadows ;-)Cheers, Holger

If FS11 ships with absolutely no aesthetic improvements other than real time cloud shadows then I would be perfectly happy with that. It would do wonders for the visual realism of the sim. I understand that it's a difficult thing to add given the structure of the FS graphics/scenery engine, but it's seriously long *long* overdue. Lomac's had them since 2003.Here's hoping.-mike

Some talented script guy should be able to enable cloud shadows quite easily. All you need to do is take the environment cube, filter the clouds and map that onto the ground. In theory, I'd know how to do it, but I've never done any dx shader programming...What sort of performance penalty you'd get I don't know though.Christian

I disagree, the environment cube cannot be projected onto the terrain to achieve realistic cloud shadows. The environment cube is in no way related to the sun's position - rather the camera's position!What you need is a projection of the clouds from the sun's vector onto the terrain mesh. This projection could modifying the already existing shadow map textures. These currently appear to have 256x256 pixel resolution. So the shadow edges unfortunately appear somewhat blocky.Fly at sunrise or sunset in mountaneous terrain and you can see these shadow maps. They're updated in "almost real time", a bit too slowly for moving clouds though. I just wish the light/dark contrast of the shadow maps was much stronger.To generate the shadow projections, one also needs the cloud positions.One could hook the DirectX API to get these cloud positions. Hint... Tileproxy already has some DirectX9 hooks - grab the source code if you want to try this yourself ;)

Well, I have to say I wouldn't really care about sun direction. Are you really going to notice that when flying? While this is a quick and dirty hack it's still better than what we have now -> no cloud shadows!Christian
