Version 3.00 - Alpha10.1 (30.04.2016)

[aoktar]

hello,

I dont understand, why octane suddenly doesn't show anything in the live viewer at frame 377 (everything works well till frame 376). I want to scale a cube in the z dimension with blackbody emission texture on 2 polys, but after a certain value (around 65) somehow it doesn't work anymore.
Log shows

Singular matrix:
-0.000 -0.000 -65.208 0.000
-0.000 1.000 -0.000 0.676
0.010 0.000 -0.000 -0.000
plugin already locked the result!

I kicked everything out of the scene, there is nothing really in it. Could be a bug?

sorry: win 7 64, r17.048, alpha 6 both plugin and standalone. latest cuda 7.5.18, 780ti and 780 3gb

frame 377 disappear.rar

Thx for very informative post!!! Please try to post somethings better, some images or scenes for next times. But i see there is an error message about singular matrixes. Always try to be away from using Scale=0 for any axis of scaling.

Oh, I've edited my post 3 times after posting the original one, please look again Somehow it didn't take my scene.

Got it! Anyway would be nice to see a sample scene maybe to fix it. Here is added a warning about possible same issue. It's a Renderer related topic and i'm not sure that's possible to fix without loosing performance.

At the bottom line.

Thank you.

I found out something (and there is a sample scene attached to my first post, I don't know if you have seen it).

Always try to be away from using Scale=0 for any axis of scaling.

No scaled dimension is ever 0 (x scaling goes down to 0.01 though). And the error appears when scaling Z - somewhere in the area around value 65. Strange!

Just confirmed (changed the scaling to 2 instead of 0.01): It seems 0.01 is considered 0 and outputs the singular matrix and "plugin already locked the result" - why this occurs at frame 377 and not earlier, I don't know.

why this occurs at frame 377 and not earlier

Post a scene if you want to know. So we can check what happens. But that's clear matrix has strange values.

I still don't know if you have seen it:
Sample scene is attached here viewtopic.php?f=85&t=51856&start=220#p268415 (it is in your first quote already, too - I edited the post immediately after realising that it didn't attach the scene).
and changing the x scale value from 0.01 to 0.013 or something bigger changes the frame number, where the render disappears (so it's not 377, but a few frames later).
I attach the scene again here

Thank you very much!

I'm checking...

Alpha 6.1 build is available. Enjoy it!

[Yambo]

YES!

BTW - Just so you'll know, i'm working with those alpha versions on production and it''s pretty stable.

Also, what is the problem on mix materials that been fixed?
