Parameter expressions not evaluating in vrayLightDome

[Hannes Drossel]

Hi!

Im trying to reference a texture from one place in Houdini into the texture parameter of the vrayLightDome using an expression.

The expression looks like this:

`chs("../../myNode/file")`

I can see that the string evaluates correctly in Houdini and I can see the texture on the dome in the viewport but I cant get the texture in the render. It appears to not evaluate correctly on render.

Cheers!

Ok so I narrowed it down a bit. It turns out that it was the path in myNode.file contained an environment variable, $SHOT_ROOT.

Like I said. the path is evaluated in Houdini but not when rendering.

Attaching a simple scene:
vray_expression_evaluate.zip

Everything is exported correctly. Check your file path.

Got it working now. Not sure why it wasnt working before. The path was indeed correct in the vrscene.
We had a frame number in the filename. removing that from the filename solved the problem.

Thanks for looking into it!
