Does RT respect Turbosmooth render iterations?

V-Ray V-Ray GPU Issues

I have some objects with Turbosmooth modifer applied on them. I’ve disabled the Turbosmooth iterations in the viewport and have set them to “2” so the objects are subdivided only in rendering. However, the objects render as if there is no Turbosmooth iterations applied. I tried both CUDA and CPU mode. Please check the screenshot below:

My guess would be that since you have RT in Activeshade it isn’t seen as a render per se, it reflects your viewport, i.e. it looks just as it does on your screen. Set iterations to 2 for screen as well.

Sounds logical to me. Thanks.

Yes that’s right. In fact almost all preview options (the way you see them in the viewport) are those who are valid for RT. For example RT will render the view count (and not the render count) of most 3rd party hair plugins (Ornatrix, HairFarm ..).

This is only when used as an ActiveShade renderer though; if you set V-Ray RT as a production renderer in 3ds Max, it will take the render version of the geometry.

It does work when RT is in Production mode, just tested it. Good to know! :slight_smile:
