Only assigning a material to an object -> crash |

It would be nice, if I could read something like:
Ok we, the developers, read your message and took
the dump file. We will look for the bug and try to solve the problem
I do not like to be disregarded :mad: |

Wigand, does it do this 100%, can you post steps to duplicate?

Thank you Jack for responsing.
I am sorry, 3 days are gone, therefore the scene is already discarded.
What I can say is this:
I created an object in Silo
It had very much vertices.
I used LUUV to import it as *.obj
I assigned a vray material.
Crash.
I do not know what is inside of the dump file.
So I do not know what else the developers need.
Not everybody likes to post the scene or object
to the forum. |

That's helpful info though Wigand.
My guess is that it could be a bridge issue. Or a memory issue if the geometry was high density...
Hopefully the devs will come up with something.

Amazing I can confirm this I just had exactly this crash under Vista, dragging a Vray texture on to an object and an application hang and Vista needing to close TS7.51 down - no crash report offered sorry support
I immediately loaded XP and ran the same scene and dragged the Vray material and- a pause of almost 30 seconds and then all was ok and no more problems

Wigand,
Took a quick look at your Pilz model. Certainly no explanation there. The geometry looks excellent, no overlaps or artifacts that I could see (many 3D programs will crash in dealing with bad geometry), so the issue seems firmly in how trueSpace handled it. Best of luck.

PS. Just read weaveribm's post. Vista? From what I've read, very few applications are stable on Vista, with both M$ and the application developers still scurrying to improve things. (I am certainly in no hurry to even contemplate getting Vista, maybe in a year or two when the stability is improved and I have no other options, and then probably only on a new PC pre-installed -). |

Tag Wigand,
this is a bit mysterious object you got there, wonder if there is a reference to the other error where parva said something regarding the UV map
It was impossible to assign a material with a texture to this object. If I took for example the green leaves from the VRay mat lib the mushroom became completely silver, no green or sign of the leaves. Same by the way for DX material, colors yes, but textures never were shown.
Managed though to assign the orange glass without a crash after working a bit with it, let's say I made it a bit "passend".
Attached the object now with orange glass, please try it if it works I'll reply what I did, if not the real experts have to give their coments;) |

It is possible the polygon normals are just coming in inverted/reversed?

I wonder if this is an issue with drag'n'drop. Do you get the same problem if you assign the material from the ME?

This happened again last night under XP Home
But at the end of a long successful animation render so not too annoying
Thanks Jack will try the ME way if I can find out how to do that, drag and drop yes a Windows function so could even be graphics card drivers... perhaps we should add our drivers' info to our sigs that might help Caligari support - ta for noting the possible workaround mate

Nah the drag and drop code is part of TS but it's likely handled seperately from the ME implementation so it's possible that there could be a bug in one without being a bug in the other.
The materials in the vray material library are just presets using the built in shaders. You should be able to make any of those materials by using the built in shaders and textures via the ME.

the drag and drop code is part of TS
Are you sure Jack? I'm reasonably confident :) that TS windows are Windows windows. Or TS is not an integrated application, this is why Ctrl+c and the other standard Windows functions work in there
Best always to use an operating system's basic functions than to write code that bypasses the standard Windows functions. It takes more time, is less portable, can be a maverick and so on. Can't see 7.51 being other than a forward-looking application which means an integrated application under Windows
Of course if TS code bypasses standard Windows functions then that would explain why dropping an icon on to a window crashes the application... :)

Yup. Buttons are windows controls for example and the programmer codes what happens when they are clicked. It's the same way with drag and drop. Windows just passes the information about the dropped object, it's up to the app on how that's processed.
Windows is just an event and graphical system, the programmer has to implement window functionality. Even handling CTRL-C as you mention has to be coded by the programmer. There are libraries like MFC, .NET etc., that provide standardized components for the programmer to use and save him work though.

-Jack.
Yes I get the same problem.
It is important to simplify the mesh and then assign the material.
Both , drag and drop and ME bring crashes.
I assigned the material to a TS-Sphere then used the pipette to get
the material into the ME then drag and drop to the object, crash.
And the same by assigning the material direct from the ME to
the simplified object. |

Same result with clicking on the Funnel (assign material) icon on the material editor as well?
There's also the posibility that this could be a DX shader issue as well since a DX shader is created to mimic the Vray material for the realtime display.

Just a remarc, in the sample I provided above I used drag and drop with positiv effect, so should that really be the only point to focus on ? |

to
the simplified object.
This step is the important step. You have to simplify the object
before assigning the material, to get the crash. |

Hi Wigand, thanks for these reports , I had reported a similar issue to this a few weeks ago, but I think your one is related to the same problem.
I'm sorry I missed your original post here , its easy for them to get buried here and overlooked .
You could send your dumps and a description directly to support and they will be sent along to the respective developers in a timely fashion .
the forums are good for things like this but the reports sometimes although very infrequently though get missed and are not picked up by someone and sent to the beta for the developers to see , or they could be reported already and an answer or update gets overlooked and isnt posted back to the original threads here.
be assured this is being looked into. |

Not in my case no the object was not simplified first.
Sorry if I'm missing your point there Wigand but to pass back info to Caligari support, maybe our crashes are not related to the same function or something
