Emitters + Framework

[macklebee]

The Pointlight + Waterplane issue:

 

Simple scene with 1 pointlight, 1 waterplane, terrain, and 1 directional light.

 

Plight.zip

 

Use bmax to load the scene and the program will crash if you try to view the pointlight and water at the same time.

 

Remove one or the other and all is fine.

SetWorld(fw.transparency.world)
then create the emitter
and set its properties
...
SetWorld(fw.main.world)

 

But there is a bigger issue happening here. Any emitter created and saved in an Editor scene will crash a bmax program. Same thing happens with pointlights and waterplanes. Both emitters and pointlights were worked on during this update. So I am hoping Josh just forgot to upload some new files...

 

Thanks thats got it working. I was so close last night just didn't get the right words in setworld.

 

By doing this I can now have a directional light + a emitter and no crash. I haven't tried doing any tests with pointlights + water yet.

you have emitters working from LoadScene() on an sbx? odd .. as it will still crash for me when there is NO light of any kind in the scene ... or for that matter anything else, even trying to load a scene that contains only a single emitter causes the crash to.

What I have working is the code above now. The sbx contains the scene + lights but no emitters. The emitter is just the snow effect. I think that I am still using 2.3 the version.txt says 2.3 if I run the updater it doesn't say there is any files that need to be updated.

[carlb]

you need to to get the latest version of the downloader from the download section to get 2.31

and it will say 2.31 in the version.txt

 

hope that helps

[macklebee]

heck... that explains it! if I was you quan i wouldn't bother with downloading 2.31 until these issues are fixed. right now the version you have doesn't have these issues. What we have been referring to are all issues that belong to 2.31

[Marleys Ghost]

Aha .. I'll stop wondering why emitters not loaded with loadscene work in 2.31 then ..

[Quan]

Ok will do. I'll wait until things have settled down before upgrading. Still I have learned a lot more from this thread even if my problem was a bit of a wild goose chase in the end.

 

Btw, I am making a space game but got obsessed with trying to make snow, but it doesn't snow in space

no, i wouldnt say a wild goose chase... it made us take a look at emitters and pointlight/waterplanes in 2.31 and find that there was an issue now. the only thing that was confusing was your ability to get something to work when it just failed no matter what when we would try it in 2.31.

 

who says it doesn't snow in space? you are mighty quan, the creator of your game's world. if you want to make it rain guinea pigs that shoot lasers out their eyes that is your decision.

[wh1sp3r]

i tried all your examples .)

 

Quan's example is not working for me, still stupid zero message error and crash, lol.

[Quan]

Have you tried it with:

 

SetWorld(fw.transparency.world)

 

Before the emitter and

 

SetWorld(fw.Main.world)

 

After it ?

 

That is what I did in the end to get it to work but I am still running 2.3 and haven't upgraded yet.

[Marleys Ghost]

i tried all your examples .)

 

 

 

In Bmax or C++ ?

[wh1sp3r]

c++ of course

[Marleys Ghost]

c++ of course

 

And you can't load the example emitter scene?

[wh1sp3r]

everything crashes with zero messagebox.

In editor, emitter is ok.

[Marleys Ghost]

odd, I had no issues with C++ and emitters and the test scene above loads fine.

 

 

It would crash an app in Bmax, but thats fixed now. The only issue is the waterplane one as outlined by Mack.

[Marleys Ghost]

everything crashes with zero messagebox.

In editor, emitter is ok.

 

 

hmm, well I am using a basic scene loader in both Bmax and C++ and can't get Bmax or C++ to crash I even went as far as adding 3 Directional lights, 4 emitters of varying type and threw in a spotlight and a point light oh, and an ambient light just for chuckles sake ..

 

 

no errors.

 

I should add, also enabled in each app was: SSAO, AA, HDR, Grays and Bloom.

post EXE

[carlb]

or sample code please

[Marleys Ghost]

post EXE

 

 

Why an exe ?

It works for me in C++, now as i use

 

SetWorld(transparency)

CreateEmitter (...)

SetWorld(main)

 

Creating the Emitter in the main world results in a crash and the "0" message.

I only have so far used loadscene.

 

The Code I have used for testing:

 

Bmax

 

C++

[macklebee]

The emitter lua script uses:

SetWorld(transparency)
CreateEmitter (...)
SetWorld(main)

[wh1sp3r]

no no, It still crashes .. no without 0 message I tried example from wiki too.

 

There is something wrong, because my demos from 2.27 2.28 works absolutely fine with emitters ...

 

+, you have NVIDIA cards ;-)

[Marleys Ghost]

I think carlb's using an ATI card .. maybe he can confirm an ATI issue?
