Hi,

The GTX 660 Ti is not in the machine anymore, still black material.
Have the latest Modo 10 version and 2.25 (2250000) version of Octane.

Tested with a random jpg and now a modo-udim, both show the right UV map.



Am I doing somthing wrong?

Did you check the Modo Event Log and the Octane Log?

Also - it is worth trying the latest Octane 3 plugin, since it has some additional fixes for Modo 10.

Can't find the Event log

Update: Found it.

Uninstalled everything and installed Modo 902 sp 3 and Octane plugin 2.25 (OctaneRender_for_Modo901_2_25_0_99_64bit).
Still the same error.

This is starting to get frustrating.

CUDA error 719 on device 0: An exception occurred on the device while executing a kernel. The context cannot be used anymore and must be destroyed. All existing device memory allocations from this context are invalid and must be reconstructed.
-> kernel execution failed (pt)
device 0: path tracing failed

Can you pls have a read of the link in my signature - particular reading nvidia driver versions and checking for a hardware fault. And it would be worth sending me the scene that is giving you problems pls.

Paul

Sorry Paul,

Have now done all those steps and here are some screenshoots.




If you want I can send you the scene, how do you want it?

Thanks for the additional info - and sorry you are having problems. The Cuda error is completely separate from the texturemaps not rendering. It appears the cuda errors how now been resolved?

If you want I can send you the scene, how do you want it?

Yes, pls send it. Dropbox is fine, or any other file share system.

Paul

You got mail.

Haffy - thanks for sending through the file. There are a few issues...

1) Your UdimGraph node has 28 UDIM texturemaps in it. It looks like Octane has a limit of 25 texturemaps in this situation - and if you go over 25 Octane will throw a range of Cuda error. I have reported this to Otoy - so perhaps they can fix this. I have also updated the plugin to give an error message if you try to create a UdimGraph with more than 25 texturemaps.

2) The .lxo you sent me loads into Modo without any UV's. For example, selecting the Chassi No Dupli mesh item has the UV Vertex Map OFF. So Octane is not receiving any UV's.

3) If I set the UV Vertex Map to Texture - Octane then gets UV for the hotrod geometry, however all the UV's are in the range 0 to 1, so they are not setup for UDIM's.

So it looks like something has gone amiss when you imported that geometry into Modo, or when you prepared the scene for me.

I hope that helps.

Paul
