Houdini to 3ds Max USD workflow

[frodopytlicek]

Hello,
can someone help me with this topic? I have no luck to transfer data correctly from Houdini to Max via USD. I tried Max USD Stage and VrayScene loader and its without materials or it not render at all. Is there some tutorial for this? I found only 3ds Max to Houdini official Chaos tutorial. I'm using Max 22 with USD 0.4 and VRay 6.1 and Houdini 19.
Thanks

Dear frodopytlicek, hello.

I have tested some USD files exported from Houdini and they worked.
On this topic very important is to define the following:

• exact V-Ray for 3ds Max version (screenshot from Render Setup > Settings > About V-Ray)
• exact V-Ray for Houdini version (V-Ray > About V-Ray > Copy to Clipboard and paste here)
• will you be able to share with us an example file so we could take a look closely

Please be aware that support for USD 0.4 was introduced in V-Ray 6 Update 1.1, so you will need at least this particular version or the next one (Update 1.2).
The file could be shared here in a .zip or via our contact form if you prefer.

We will appreciate to take a look at the file and investigate is there a still non-supported workflow or what in general could be involved as a reason in your complication.

Best regards,
TS

Can you check this? We eventualy got material working but now we have problem with animation.
Houdini 19.5.435, Vray 6.00.21
Max 24.3.0.3404 (which is 2022 update 3), Vray 6.10.20

Thank you!

Interesting scene indeed.
In Houdini the files works pretty well, tested with V-Ray for Solaris.

Your observations about the animation are right, will share my results with V-Ray for 3ds Max team.
And you will be notified by any news.

Reported for further investigation with VMAX-13637 number.

Thank you once more for the provided scene!

Thanks. Can you provide some time estimations or description why its happening?

[tsvetomira.girginova]

You are welcome.

The current suspicion is a relation to Instancer and its implementation.
VMAX devs could share more specifics and possible estimation.
Will keep you posted.
