OK, this is weird and been going on for a while but I waited until 7.51 to see if it was fixed...it is not.


I am working on the little cloud but cannot continue using Vray as it crashes doing the same thing.


I am trying to paint to floor plane with a beach/sand texture but after I paint the object tS crashes out every time on two PC's; Vista and XP.


As you can see in the shot below I have managed to paint the plane without a crash but ONLY if I scale it down small enough to fit within the frame of the image.

Every time I scale it up bigger than the window size (400x500 here) tS crashes out.

I have GI on and soft shadows but cannot yet find a way of stopping this rather than keeping the plane as small as the image below.


Am I going mad...anyone else able to repeat this...is it something in this scene?


I really cannot move on with tS if this is a Vray bug....:(


Nor am I happy to move all this over to workspace if it turns out to be a bridge/model side problem....

I cant get it to crash however if using the paint brush tool in the material editor the object gets painted but renders blank. I mean blank. Nothing there. if I use the fill tool instead then it renders ok.

Don't know if that helps to point to what the issue may be for you but it does seem that there is an issue.

edit: I re-read your post and you seem to be saying you do the texturing in modeler then move over to vray to render. i tried to carefully follow your steps but could not crash Truespace doing it. Did it ask to create a dump file for the Caligari folks? Thats supposed to be enabled by default now.

Cheers

Nope, everything here is done in model side although the bridge has to be enabled to render Vray from model side.


No dump file being requested here in Vista either....:o

Right with that clarification I understand fully what your doing and It doesn't crash for me. I assume you tried another texture to paint.

And thanks for pointing me to the ability to render Vray from model side of things.

Cheers

I have tried a few textures and it always crashes but only when the object is scaled up but not always in a new scene...just this one...:o

Okay, I can repeat with a new scene now;


1. Open a new scene in model side

2. Open a new 3D window and set it to 400x500

3. Place a plane in the scene but make sure it is small enough to be seen within that small 400x500 window.

4. Ensure Vray is selected and that DX render mode is off for both main window and small window (all this is still in model side)

5. Open the old style ME and load a texture then paint the plane using the Paint Object icon. As you are in wireframe display mode you will see the object rendering in the working window if in DX mode you might not.


Everything might be fine here but...


6. Scale the plane up in all directions so it is much bigger than the view in the small window. Now use the Paint Object icon from the ME...


Crash every time for me.


need a big plane for the base of my render so I cannot see any way around this without switching back to LW...:mad: :mad:

Hi Splinters,

I know this is going to sound kind of stupid (I usually do anyway) but I have an idea it may be some bug with the mathematics of rendering that specific sized window.

For instance...

Set up your scene completely for render with the painted beach scene already scaled as large as you need it to be. Now render that scene in a larger aspect, say 800x600.

If that works it can be postwork cropped of course, and I've had that same render window size problem with other 3D Apps in the past, so it could just be that.

Hope this helps,

Does it crash if you are in solid rather than wireframe? My first thought is the crash is caused by V-Ray being asked by the system to render the object alone without the rest of the scene, which happens with a material repaint is used in wireframe mode.


If you switch to solid and paint the texture, no render of the object is called (as you can see the update in realtime). Could you try that and see if it causes a crash?


Also, could you try painting it so you get the texture applied succesfully, then try rendering using Render Object, see if the result is the same as when the ME calls the render for the object? (testing with object smaller than window and larger than window would be good there, to see if it too shows the same difference in results).


Thanks!

Tom

Thanks 3DVD, I had a feeling it might be that but when you have GI, SSS and soft shadows on a crummy laptop you try to be conservative with what you render.


hang on a mo....I rendered a standard window and all was fine, changed window to 400x500 hit paint object....crash.


Cheers then 3DVD, I can work once more but what a stupid little bug...:(


I have always used this method with LW but I really want to use Vray with this project.


oh well, render large and crop it is.....

Great!!!!

Well... the problem with the window size is still there though...

I'm really happy my advice actually worked though, come to think of it this may be the very first time my advice helped anyone! :D

Glad to hear it worked... but now you still have to play with the camera to reset your aspect the way you first intended to view the scene. That's always fun too!;)

Check Tom's advice here... it sounds like it may be more accurate to the problem, and he is after all a hell of a lot smarter than I am!:o


Glad to help tho -

Here is the dump report if it helps. I will try those variations Tom...cheers.

Ok here goes, with a window of 400x500;

DX mode does not crash when using paint object but it does crash when I render the object in this mode.
So you are right Tom, it is the realtime updating of the texture that causes a problem in this window format but I am also seeing it crash when the object is rendered...
:o
Guess I just have to change render size (format) until the culprit is found here....or be very careful to work in DX mode.
