( open ) [ HOU-2564 ] Houdini 18.5.408 with Vray 5.00.50 crashes

[creac]

Hi, I get a "19196: Fatal error: Segmentation fault" error when using Houdini 18.5.408 and vray_adv_50050_houdini18.5.408_9ea6717_13034 build.
It happens when trigger the render from the vfb icon.
I also noticed the Vray shelves are visible but empty.
Anyone had similar issue?

I'm not 100% sure, but wasn't 18.5.408 the houdini version that had issues with packages? Might wanna try 18.5.499 and up.

[creac]

ronald_a Thanks, indeed I didn't see the recent 18.5.499 build.

[creac]

Still have the same issue with build 18.5.499
Fatal error Segmentation fault..

Get back to build 408 and everything works good.
I guess something is wrong with build 499...

[ronald_a]

you need the appropriate vray build for 499 as well btw.

I installed the following:

houdini-py3-18.5.499-win64-vc141

and

vray_adv_50050_houdini18.5.499_9ea6717_13036_windo ws

[ronald_a]

not sure about the py3 version of houdini and that build. I believe python 3 is only supported with the latest (5.1 core) build. I could be wrong.

[chakarov]

Python 3 versions of Houdini are supported in V-Ray 5.10.x and up /27th April/.

creac , 18.5.408 with V-Ray build 13034 is working fine on my side.

[tzoil]

Hi!

Sorry for the question but should the 5.10.x beta be seen among the nightlies by the licensed user?
Should I write to support if I don't see it?
(I really want to try the houdini 18.5.408 python 3 with vray but the vfb is always crash for me as you wrote above)

[creac]

My mistake, as ronald_a mentioned I first installed two incompatible versions mixing Houdini Python with unsupported vray release.
chakarov I don't any issue with 18.5.408 and V-Ray build 13034 which I have been using for quite a while now and is very smooth.
However I have some issue with 18.5.499 release.

Here are the version I tried
houdini-18.5.499-win64-vc141.exe
vray_adv_50050_houdini18.5.499_9ea6717_13036

I noticed some issues with the menu that doesn't work properly. Also some weird behavior with camera that doesn't update correctly in the VFB..
I will stick to 408 for now waiting for the next stable release.

thx

[chakarov]

Hello creac, I've reproduced the IPR issue where camera is not properly updated. But can you be more specific with that menu which doesn't work.

Hi chakarov , here is attached a screen capture. thx

[chakarov]

First three menus should list the existing V-Ray ROPs in the scene, otherwise they are empty because there is nothing to be listed.
