been a while. Was a bit crunchy here the last weeks. Anyways i am in the middle of using Krakatoa to retime a bunch of fluid sims.
And i am experiencing crashes when switching to Playback Graph mode. It seems to be related to display tho as it doesnt crash if
i turn off display completely. I am still trying to track down the exact problems as i did manage to get it to work with one of the Simfiles
that i dont get to work now in a different scene.
Anybody been facing that already ?
Workflow:
Simulate in Realflow
Load the Bin into an empty scene
Add a MagmaFlow to compensate for Simualtion FPS and fix the velocities (Thanks again Bobo and Darcy !)
Save out to a new PRT
Load PRT in a new scene
Enable “Playback Graph” -> Crash
In an empty scene i once managed to get it to work by turning of display, enabling the Graph and then turn on display again,
but i cant reproduce this now in the production scene.
Damnit. Just after posting it i found out why i got it to work once.
The Problem is dependent on the renderer. When i switch to Krakatoa it works.
If i switch to krakatoa, enable playback graph and display and then switch back to vray it doesnt crash on switching,
but as soon as i move the timeslider
Thanks, we will try to reproduce this. We have heard from at least another source (Chad Capeland of Anatomical) of a similar crash related to PRT Loaders, but we have never experienced this. If we cannot repro with our own PRT files, we might have to ask you to send us some.
Launched Max 2008 64 bit in WinXP 64, running DirectX 9 viewports.
Assigned VRay (1.60.35) as the current renderer (startup default was Scanline).
Created a PRT Loader
Selected your sequence
Enabled Playback Graph
Played with the Time Slider and with the Graph spinner
RESULT: No problems.
Keep in mind that I used the current build (nearly Beta 7), although that might not have anything to do with the results.
Also from Chad’s reports we know that the problem is not necessarily fully reproducible. We use Krakatoa in production a lot and we would have hit this problem long ago if it happened on our machines, so it might be computer or installation specific. Any additional info about Max version (32 or 64 bit), video drivers and so on might be helpful.
Max config is same as yours. x64, 2k8, DirectX9. Driver Version is 182.06 on a Geforce GTX 285 1GB in a corei7 with 12GB Ram.
I’ll try updating the drivers asap. So it might take me a while as we’re in the middle of a production.
Don’t touch the drivers yet.
Wait for Beta 7 (SOON!) and see if it still behaves the same.
We will look through the code and try to figure out what could be going wrong in theory.
