Hi There,

So, I have seen a few posts stating the same issue but not seen a solution, or at least I haven't found one!
Everything else works fine, USD imports/lights/loading the plugin etc(or at least I think it does). Licenece states it is active but it doesn't render via the viewport or to disk, and all the logs do not have any errors, it just sits there saying "Generating scene".

I did this with a USD asset and then tested it with just a sphere and same result! Is there something really obvious I am doing wrong!

I have also got Maya installed on the same workstation, would this cause the issue?

The consensus seems to be that SideFX changed the licensing requirements so you can no longer use Arnold in Render View with Houdini Indie. https://forums.autodesk.com/t5/arnold-for-houdini-forum/cannot-render-houdini-20-5-332-htoa-6-3-4-1-quot-no-valid/td-p/13103126 [forums.autodesk.com]

Hi Brian,

I hope all is well, thank you for getting back to me. Yes, that is what I was seeing/reading, the odd thing was I wasn't getting any render using the "render to disk" - or at least I thought I wasn't!

I could see it was generating an image file, but then it was stating that the file was broken....

Then, just tried it again and realised it was a complete noob mistake!! So the issue was, I was setting the filename to .png as a quick test, but I left the file type to exr, so the image format was broken - DOH!!! So I now have made sure the below items match up!


Now I just need to work out how to render the Arnold USD files, the .ass files render but not .usd - next hurdle
Also need to figure out shaders, as everything is grey at the moment, except when I loaded the .ass export from Maya - lots to do!


Actually, I have got usd working, it just didn't have a shader attached, just need to figure out shaders with usd within houdini, I created an arnold surface shader and assinged it to the usd and it showed up etc!


OK last bit of waffle from me! It turns out that the USD file I was loading didn't have textures working, or they were broken etc, I loaded in two other usd assets and they are fine and load!


I would say this is sorted now!!

Thanks again for the help.
