Render fire in Redshift for Max?

[Fabrice]

Sorry but same newby problem again (trying to render smoke in Redshift):
- I create a FumeFx + SimpleSource and sim it
- I set its Volume shader shading to "Arnold/Redshift volume
- I set RS to brute force GI
- I assign an "RS volume" material to FumeFx001 (with Smoke assigned to emission channel)
- I create an RSphysicallight and set its "Volume contribution scale" to 1
...and nothing renders...
